Cryptoscammers everywhere rubbing their hands together. There's so many ways this could go wrong. Everything from prompt injection, to being tricked in running a specific scammers setup, to which they can pump and dump specific stocks, and all sorts of other manmade horrors.

Hello $claw, i'm a Nigerian prince..

This is wild. I nearly got banned from Robinhood for just running DCA using an unofficial python api. Crazy how times change.

The world where people used LMMs to make deterministic programs that would trade via API is the relatively saner one that ought to have been.

How come you used robinhood unofficial API instead of say alpaca markets, ibkr, or td ameritrade?

I don’t understand this constant fascination with having language models trade stocks. Language models are very useful tools but not aligned at all with generating alpha.

The usual question: what's "aligned with generating alpha" that a human stock trader can do, but an ai can't?

That is sidestepping the point: 70-90% of retail traders lose money. The question should be: is AI trading enough of an improvement to justify its non-subsidized costs?

Just like any useful tools, there would be an expert super tool user who could probably generate enough profit based on the tools. The majority would not profit from it in the long run (the monopolistic tool makers would reap any profit from the value chain.)

The humans can't either

I don’t understand these arguments. You have to realize anything an LLM does has been exploited for decades by well funded shops.

AI agents for trading, as well as 24/7 trading are no different than offering sports gambling and prediction markets to the masses; it is a vacuum for the fiat of the unsophisticated. The goal is more trading volume to generate more fees, similar story with private equity wanting access to 401ks to unload PE at peak valuations to bag holders.

https://en.wikipedia.org/wiki/Parable_of_the_broken_window

well said truth

Maybe synergistic with tokenmaxxing. You should be burning more tokens, and you should also be making more trades.

The only way to win is to not play.

https://www.bogleheads.org/wiki/Getting_started

Bogleheads are still playing.

Bogleheads is maximizing potential economic gains from investing in the capital market while minimizing costs from the exposure attempt.

The results from dollar cost averaging into VT or a target date fund for the next 30-50 years is likely superior to gambling on single named securities or options, for the unsophisticated.

Right. But you're still putting your money at risk seeking reward - aka playing the game.

Outside of FDIC insured cash accounts, the most anti-gambling way to play would be to buy nothing but TIPS. But even those have a (small) risk.

They’re great at generating alpha, just not for these users.

They’re possibly great at generating alpha in highly complex systems that compose LLMs with tabular machine learning and other analytical techniques at a large scale. So yea, certainly not for these users.

I use the Interactive Brokers MCP pretty heavily. I don't do any cool automatic fun "trading", but instead I use it to have "pseudo-QQQ".

I didn't like the relatively high fees for QQQ, and I realized that Invesco releases the weights for QQQ for free. I also think Tesla is too overvalued, and I want to avoid the SpaceX IPO. With the Interactive Brokers MCP, I just feed it the CSV of QQQ's weights, tell it to remove and redistribute Tesla, and then I tell it to buy "$1000 of pseudo-QQQ", in the form of raw stocks.

Doing this, I still basically get the same exposure as QQQ, without any fees.

EDIT: Some of the responses here were right; this is a actually a bad idea, at least with the naive way I was describing it. There's a lot more tax stuff that you avoid with ETFs compared to the makeshift thing I'm describing.

This is fair use, but an average person will just spam LLM with "give me money making strat"....

QQQ gets the leverage from, among other things, swap agreements and futures. I don’t think what you have could be reasonably considered “pseudo-QQQ”. It’s like copying a cake recipe, but leaving out the flour and eggs because they are too expensive.

Even given that, I don't see any reason I couldn't also just mimic what QQQ does with the MCP.

Real question, where are you going to buy the swap agreements?

If you're asking about the average person, no.

I am in the "false confidence" stage of Dunning Kruger Syndrome for finance stuff, so I personally would do swap agreements, but I'm not an average case.

I realize I might have been mixing up QQQ with ultra pro QQQ… anyway, yeah, you can replicate QQQ. I was thinking of Ultra Pro QQQ.

I mean, even still, my point stays the same; if you have access to their strategies, I don't see why you can't just get the MCP to directly mimic that.

Because it is not possible for you (personally) to buy the underlying components of leveraged ETFs.

Yeah, actually I think I was getting confused on some of the terminology. It looks like you're right.

Still, as you said, just mimicking regular QQQ is achievable.

It’s achievable. It’s called “direct indexing”, and there are some extra costs associated with it, so for most investors, I think it is cheaper to get QQQ. You can flip that around with tax loss harvesting but I don’t understand that strategy and I can’t explain it.

You also don’t need AI to do this. Before AI, the main barrier to direct indexing was the amount of capital you need. That is still true.

I have enough capital to where I can do everything with the incremental share threshold of Interactive Brokers; as such I don't have to deal with the fees associated with normal direct indexing.

Sure, but I wasn’t thinking of the brokerage fees. Things like the spread.

I feel like you could probably have the AI write a script that uses the API to do the same thing, except this time you have code you can test rather than relying on the probabilistic machine every time you do a trade.

I did that first actually.

I don't let it buy anything without confirming, and I will load the CSV into Google Sheets to make sure that the numbers more or less correspond to what I think they will. It's just easier to directly use the MCP and set up some custom skills for what I want to do.

Dunno, it seems to work fine.

I have thought about this but snag on rebalancing, because it would create a taxable event, or be drawn out over months/years.

Although maybe a bit spicier, VGT is half the cost of QQQ, so that is what my "NASDAQ" has been. I also blend in VTI to cut the volatility a bit, which is 1/3 the cost of VGT.

I'm doing the same strategy for rebalancing that QQQ does, and I figure that the headache of tax time is a "Tom in 11 months from now"'s problem :)

Some tax software nowadays will allow you to simply upload the tax documents with all the transactions and it will tabulate everything for you, so I don't think it will be too hard for me.

I'll admit that there's primarily just kind of a coolness factor to be able to say that I ripped off and copied QQQ without any fees, but I do genuinely like the idea that I can avoid companies that I think are terrible in the process.

You don't need AI for this though. I was doing something like this with a python script and a crypto meta etf I created years ago. I even had some simple heuristics for selecting what coins and quantity to purchase given trading volume and spot price. Its like 175 lines of python. Probably could be a lot leaner too.

I agree I don't need it, I actually wrote a program to automatically buy and sell stuff years ago using Alpaca [1].

I just found it a bit of a pain in the ass to manage a service to do that automatically, vs thirty seconds of chatting and getting results immediately, and having something that can be supplemented by RAGs in the process.

[1] I swear I had a blog post about how I did it somewhere but I seem to have misplaced it.

It sounds like you are just pulling weights of qqq and buying based on that though. What more management do you have to do? Just pull and parse the weights wherever they might be stored, break the investment up based on that weight. Should work until the heat death of the universe.

and then you want to track orders states, and then you want to track exit strategies - trailing stops that are sometimes internal, sometimes sent to the order book - profit targets, and then you want to track settlement statuses as balances change on margin, and how you get filled

all while dealing with different and complex broker APIs and routing to different exchanges that have their own rules and limitations

on the other hand, agents just do it and handle edge cases themselves

Right, AI agents famously never make any mistakes.

So does procedural code, the architecture supporting it and the humans writing it. I am capable of playing devil’s advocate as well

Do you have an actual strongly held opinion or counterpoint on what I wrote?

Time to market, covering bases, lower maintenance and things to keep track of all represent the utility

Have you actually put together trading strategies by having the agent drive? I've never trusted it that far and I use agents a lot at my job right now. The way I usually do it is, I break out pen and paper to do an analysis of what I want mathematically. I then have the agent build out some Python that lets me backtest and analyze my work. I read through the code (which is usually fairly compact since numpy/scipy and various finance libraries do most of the heavy lifting for me), make any changes as needed, then run my analysis. Then I run it in a production setting if I like it. But the actual strategy is something I come up with on pen-and-paper.

I have, and agents come up with the strategy and execution based on my contribution of what sectors to look at and alternative data sources I tell them to look at a certain way. My time horizons are quarters, as well as signal conversion into a variety of single and multi leg options trades

I am not sure I would trust a LLM agent to do this either. I would use an LLM to help write the script but not execute the trades.

This is absolutely and unfathomably terrible to such a great degree that I think it reinforces OPs point. It seems like using an LLM has given you the confidence to make an incredibly ill-informed decision that will cost you dearly.

Every single time you rebalance your portfolio, you will need to pay short-term capital gains taxes on any gains, as opposed to an ETF in which you simply pay for the gains when you sell your stock which can be years/decades from now. This alone will reduce your average expected earnings by 20% over a 10 year period eviscerating whatever tiny advantage you think you'll get from saving a few bucks in fees.

Furthermore, assuming you rebalance your portfolio monthly, which is the minimum you need to rebalance in order to remain even somewhat aligned with QQQ, you're basically going to be paying a MINIMUM of 30-40 bucks a month in commissions to Interactive Brokers, or 400 dollars a year. And on top of IBKR's commissions you then need to pay the pass through fees of about 5-10 dollars a month for a total of around 500 bucks a year.

Compare that to QQQ which only costs you 18 dollars a year for every $10000 invested.

I've read some incredibly foolish investment advise on HackerNews, but I think this one just about takes the cake.

But he avoids SpaceX and Tesla, which I think is probably the driving factor in not using QQQ. Maybe he values that more than $500

tombert should instead long QQQ and short the bits they don't like

You pay interest on shorting, and it requires trying to time the market, which people are famously bad at doing.

If that was his genuine concern, then instead of trying to balance a portfolio of 103 stocks... you simply buy QQQ and short Tesla at 3.53% worth of your QQQ holdings.

You pay interest when you short stock.

And if we want to talk about "bad financial advice", I think telling people to try and time the market with a short is considerably worse than "buy the same shares that QQQ does".

You pay interest on the margin you put up for shorts net profits from the position itself and cash or other assets you place inside investment accounts. You're also usually being charged interest at only a few basis points above the RFRR so this isn't "interest" in the sense of a loan.

> I think telling people to try and time the market with a short is considerably worse

Nobody is trying to time the market. If you want QQQ but don't want the Tesla exposure in it, it's a lot cheaper net to simply hedge against your Tesla exposure with a short position counteracting your long position. If you're worried about margin rates interfering with your profits, you can model all of these and come up with the optimal short needed to hedge your risk. This is standard financial practice.

Shorting doesn't have anything to do with timing the market, the reason why pop investing communities think that shorting and timing the market are synonymous is because as a whole asset prices are expected to keep pace with the RFRR assuming they at least hold their value, so taking a short position is going against the "default" market direction.

Its not timing the market if it is exactly offset by the position in the etf

Yeah, I guess this entire thread has been an inadvertent exercise in Cunningham's Law, and maybe Dunning Kruger as well.

I thought I understood this stuff more than I actually do. Guess I have some stuff to learn over the weekend!

The GP did not try to time the market. He suggested a sensible strategy to exclude a tiny subset from an index (less expensive than maintaing the alternative index yourself).

I'm unsure what SpaceX's weighting would be in QQQ but with Tesla being <3.54% weighting it would take both companies being 0s within a year to offset the cost in taxes from reweighting...

Everyone keeps saying this but I'm a little confused; you're still paying the reweighting taxes with QQQ, it's just rolled into the management fees.

https://www.fidelity.com/learning-center/investment-products...

Yeah I just looked it up myself. I was wrong; taxes are definitely more efficient with ETFs.

Now this idea is sounding pretty stupid. Damn.

IBKR has payment for order flow if you use the Lite service, so it actually wouldn't be $30-40 a month.

You still are paying the capital gains taxes with the ETF, they are just rolled into the management fees.

You can avoid a lot of the short-term capital gains taxes by only rebalancing within certain thresholds and being ok with being "close enough" to QQQ instead of being completely aligned with QQQ.

ETA:

Looked it up, looks like I was wrong about the taxes being rolled into the fees. There's some extra weirdness associated with tax efficiency of ETFs.

I still think some of the numbers the parent provided were a bit handwavey and bullshit, but I'll acknowledge I was mostly wrong in my response.

>You still are paying the capital gains taxes with the ETF, they are just rolled into the management fees.

There is just so much wrong with this statement and several others that I don't even know where to begin.

At the end of the day... if you are having fun doing what you're doing, then by all means go for it, my main concern is that people might read what you're saying and actually get misled by it or believe that you're saying something that is true. Your statement seems sophisticated enough that someone could read it, think you have actual knowledge of this topic, and come away with the idea that this is actually a remotely good idea.

For those people... please understand that tombert has no idea what he's talking about, his reasons for what he's doing are not actually because he's trying to save any fees, or because there is anything optimal or rational behind it or he's in anyway outsmarting actual institutional ETFs.

His genuine reason for this appears to be entirely whimsical and for his own amusement and enjoyment, and honestly that is fine, people can do what they want with their own money and there is nothing inherently immoral about this. My main issue is him not being upfront about his actual incentive and instead misleading people into thinking that there is some kind of economic advantage behind this.

Yeah I was wrong, I actually updated my comment right before you posted your response so I understand why you didn't see it.

I was definitely wrong; I misunderstood something about ETFs. ETFs probably are more tax efficient after all, or maybe some kind of direct indexing thing if I want to avoid Tesla and/or SpaceX.

I'll acknowledge that there's some validity in "doing things for my amusement". I do think that if I avoid selling things and instead only buy to rebalance, that could avoid a lot of tax bullshit, but that's definitely not what I was suggesting before so I'll acknowledge that I was absolutely in the wrong.

ETA:

I actually think I agree with you for the most part. I don't think it's the worst financial advice on HN but it's definitely not good financial advice either.

It's too late to edit the root comment directly but I did email HN support to ask if they could amend it for me.

If short-term capital gains taxes are the main concerns, perhaps this pseudo QQQ strategy can be done in a Roth IRA account using brokers that offer free commission?

The poster was mostly right, and I was mostly wrong, I don't like admitting that but that's just what it is.

I updated the skill I wrote to make it so that rebalancing is "buy-only", as in rebalancing will just buy shares for the underweight things instead of selling the overweight. I don't think buying is a taxable event so I don't think that's going to make me have an absurd tax burden then.

I will say that I think Maxatar was a bit misinformed about Interactive Brokers though; they've had PFOF/"commission-free" trading with their free Lite package for awhile. Of course you still pay the bid/ask spread, but if something is popular enough to be on the NASDAQ-100, the spread is usually on the order of a cent or two.

It was a creative use of AI to essentially fork your own version of QQQ, which is definitely interesting! It probably doesn’t work with a US based retail account but some Roth IRA account holders or expats in Hong Kong trading US stocks might appreciate your idea

> you will need to pay short-term capital gains taxes on any gains

Stating the obvious here, but only in a taxable account.

I rebalance frequently and on small divergences in the IRA, which has no trading fees and obviously no tax consequences.

In a taxable account I try to favor growth over dividends and rebalance very rarely.

QQQ?

NASDAQ-100 following ETF. Until recently, the only one that tracked the NASDAQ-100, which is a tech heavy index.

Too late to edit my comment, but some of the responses here were right; this is a actually a bad idea, at least with the naive way I was describing it. There's a lot more tax stuff that you avoid with ETFs compared to the makeshift thing I'm describing.

@dang if possible can you add this to my comment because I genuinely do not want to mislead anyone and have them repeat my mistakes.

I love how you needed an LLM to remove "passive" from "passive investing".

On a more serious note, why do you need an LLM for this at all? It's an excel spreadsheet difficulty level task.

As much as I hate the idea of enabling the desperate masses to gamble like this, LLMs are very aligned tools for sentiment analysis, which can be the foundation of a trading strategy. I think it's extremely irresponsible to use them for execution, though.

Sentiment analysis has been done programmatically for at least 2-3 decades. Retail using an LLM will have no impact.

Alpha is ultimately the result of analysis, of better analysis than others.

LLM's can actually be exceptionally good at research and pattern recognition, i.e. analysis. And while they aren't great at running numbers themselves, they can do exceptional work passing off Python scripts to an interpreter to generate the numerical results they need.

I'm quite sure the Robinhood AI is going to be trash, i.e. just a gimmick.

But, it's not crazy to think that with the right harness, there are big opportunities for identifying profitable strategies. Especially relying on unparalleled and essentially unlimited research capacity based on public information. More analysis than any single firm could ever hire.

And even for Robinhood users, it's entirely plausible that AI-traded stocks will perform much better than the trades a majority of users would make, since most investors are really unsophisticated.

>LLM's can actually be exceptionally good at research and pattern recognition, i.e. analysis.

No they aren't, they're good at imitating analysis based on representations of analysis in their training data. Also, Its likely that out dated techniques would over represented in training data.

Do you think Jane Street would have the returns they do if they just imitated all their competitors and everyone was using the same strategies?

This is essentially what AlphaZero is doing: https://nof1.ai/

Heh if you look at the Sharpe Ratios of the strategies/models, they're all terrible. The best performing regime there is still a Sharpe of 0.019

Yeah it looks like what uneducated retail traders would find interesting.

> LLM's can actually be exceptionally good at research and pattern recognition, i.e. analysis.

Sure but knowing where to start research is also a problem. Just saying “do research” isn’t going to work even with volumes of public information.

Well said. Lots miss this key point and it’s what I mean by alpha. Where to start, what the angle is, and LLM can help develop though I would of course argue it’s a fools errand with how crowded the space is but you could still develop an idea but it’s not going to create the idea for you.

Yeah if you have an actual really good idea for a certain kind of under analyzed data that could give you an edge but it would take too much effort or time to compile or analyze the data, an LLM has potential to make a viable strategy out of an otherwise correct but unuseful insight

I mean sure an LLM can indeed have useful ML functions BUT it is a fools errand to think an LLM at the retail level is generating any alpha. Help build a model sure. Whatever these weird mechanism of agents trading, no.

An LLM may be bad at trading stocks, but an LLM may be good at analyzing the wider context, like the news feed, to inform automated trading driven by a more sophisticated model, called by the LLM as a tool.

I don't think that this contraption should necessarily perform tolerably, but the use of an LLM is not necessarily a wrong move.

You know what they say, you make money off people chasing alpha poorly (I say this. I am they)

I think it comes from decades of fear mongering over how "dangerous" stocks and options are. If you can, instead, explain to an llm what your goals are, it can set up a simple buy-and-hold for you.

Basically what investment agents used to do in the 80s-90s where the only way to make a trade was to call someone at the broker and explain what you want.

Taking a step back, I see this as what llms are actually useful for. Empowering people to do things they might otherwise need to study and research for a few weeks to do. When ultimately, that research is just unnecessary gatekeeping.

Fidelity makes you wait a short period of time after turning-on the “stock options” setting. They also give you documents about options and how to trade them and what to look for. They also ship that same information in a booklet in the mail to you. They make a best effort to inform you of the risks and benefits. I wouldn’t call randomly placing an options bet something you would want to bypass research on…and I frankly think your line of thinking is a dangerous way of operating in the financial space. Especially where it’s critical to understand how moving your money around penalty-free works with different types of investments.

And it shouldn’t take you weeks to understand how to trade options or any of the myriad of ways you can invest.

And I don't think any of that documentation or warnings should be applied to covered calls.

Robinhood allows you to trade on the margin by default IIRC.

Also the only fear mongering I can imagine is if you were someone who thinks learning things sucks. Otherwise I’m not sure what fear mongering you’re talking about. I have never heard or read any advice to not trade options because they are dangerous. Just that you should understand what you are doing because there is risk involved.

I'm trying to see how this could be net positive.

it's a net positive for robinhood, not the trader necessarily

Net good is kinda uncalculatable here because many of the negatives are a little subjective (I'm thinking AI stock traders x-risk) imo

Sounds like a feasible world economic collapse scenario.

Original press release: https://robinhood.com/us/en/newsroom/robinhood-is-now-open-t...

No thanks. I prefer artisanal financial ruin.

Will we start seeing stock market dips and spikes correlated to model releases?

Perhaps even something like the Opus 4.7 token cost would become correlated with the market fluctuations...

No, we will not, because LLMs are terrible at trading and if they weren’t would have been adopted by professionals long ago.

They were adopted by professionals long ago, and those highly tuned and validated proprietary models are going to kick the butt of the models that you have access to every day of the week.

Those are not LLMs

Machine Learning != LLM

Maybe if we all set the model temperature to 0.

I’m using Hermes Agent and this MCP to orchestrate 5 models (DS4 Flash, GPT 5.5, Opus 4.8, Grok Build, Gemini 3.5 Flash). Basically these 5 models are making mock trades every day and keeping track of their potential losses and profit. Hermes keeps them going and making trades throughout the day.

After a month, I’m going to check their mock trading sheet and see which one was the most “profitable” and then give that agent $500/day to make trades.

You can use backtesting instead of waiting a month.

Yes but there’s many reports of agents getting back testing to work but it never translates to real trading. It seems they tend to overfit to back testing so I’m just giving them access to Twitter sentiment, other trading data thru tools and not necessarily an algo that’s been back tested. It’s why the flash models are doing better image they have faster tps and can call the tools faster.

Alas, many financial models do well in backtests and then fail in the real world. You have to expose them to all kinds of market conditions and not just the recent one. Good luck out there!

Yes even before AI, backtesting was a crapshoot. But AI adds another crease because it might have knowledge in its training. If you’re training an LLM model on backtesting, it might know that Apple crushed a certain quarter and knowing that, it buys shares before that Q earnings.

>they have faster tps and can call the tools faster.

This is like going to war with the HFT firms armed only with a stalk of celery ("it's much pointier than the tomatoes, even though those are more expensive").

Flash vs non-flash models are more about letting me know if model intelligence or model speed (with powerful tools/MCPs) are better for trading. I’m not telling the model to be fast as possible because HFT firms are already arbitraging those mini seconds to make pennies.

I wonder how much Robinhood will profit from this change.

Obviously how much the average user will profit / compile debt from this change is a lot more variable.

I was definitely wondering this. As I understand it they make money on order flow and don't charge for transactions (is that right?). But allowing LLMs to trade dilutes the true information in the order flow.

On the other hand maybe it's just chasing trends, like their previous forays into blockchains. It pays because it keeps their name in the news.

Robinhood (and retail in general) order flow is valuable precisely because there's already no information in it. It's assumed to be more or less random.

Institutional order flow can move the market, or be an indicator that the market is going to move in that direction. So executing against it a worse bet than executing against retail flow.

My bet is they won't. It's hype driven development. I work in the space(we build one of the bigger exchanges based on Hyperliquid) and our design/product people are spasming at the thought of releasing MCP/Openclaw skill for trading. I'm 99% sure it will all be a flop, month from now noone will ever know these exist but this is what everyone in that space is doing right now, quite literally, everyone. Not a single sane person will give meaningful amount of money to LLM for actual trading.

> Not a single sane person will give meaningful amount of money to LLM for actual trading.

r/wallstreetbets enters the picture... it will happen. And if it's not the "well-regarded" WSB people, it will be someone who drank way too much of the AI kool-aid.

So one of the ways Robinhood makes money is payment for order flow (PFOF).

One lens to view PFOF is that it connects the most sophisticated traders (HFTs, etc.) with the least sophisticated traders (retail).

Inventing a new, even less sophisticated class of traders seems like exactly the kind of thing that makes sense for their business model.

I was a fan of Robinhood's mission of democratizing finance and prioritizing UX for casual traders. They seem to jump on every hype train though, crypto, prediction markets, now agentic trading, whether it is ethical or not or good for their customers or not, and it seems like the distance between "democratizing finance" and "finding new suckers" is closing. Disappointing but not surprising.

I want to trade whatever I want. Why would I want them to place limits on my choices? I don't need them to be my parent.

Robinhood's crypto offering is extremely deceptive. They offer "commission-free cryptocurrency trading" but don't make it clear that you pay a 0.95% fee[1] on every trade (technically a 'spread' and not a 'commission' but there is hardly a difference). They also take 25% of staking rewards. These are absurdly high fees.

I don’t understand why anybody would use LLM:s for trading (other than some narrow speed trading news)

even in that case I would have an LLM analyzing the news trigger a deterministic API call. I can't imagine the use case for this besides vibe-trading

Totally.

Even with trading news, slop generators are way, way too slow to be useful.

Probably.

There needs to be a ton of regulation of this eventually. this will not be a problem from a safety perspective today, but a smarter-than-human agent trained on long-horizon tasks should not be given access to influence the market unless this is done very carefully.

You already could trade stocks algorithmically for decades. I don't see the value in letting the AI agent trade completely autonomously though.

This feels like when everything became webified for no reason, or everyone added features like 3D TVs that were clearly not necessary.

If you know how to trade stock algorithmically, then this "letting" part don't really apply.

This is only about removing friction for the non-professionals to rapidly burn their money...

What can go wrong? How many humans will take responsibility when they lose it all?

Robinhood didn't implement an API for users for a decade, even hindering and banning users who used an unofficial API, and now they do this. All they had to do is have a clean API.

This will completely mess up technical analysis to the point where stocks just follow a random walk.

Entering the SmarterChild economy

BonziBuddy says buy Dole and Chiquita stock now!

This is going to change investing forever. No opinion from me on good or bad though.

If there was anything missing from the average American’s economic wellbeing, it was the ability to create bespoke financial products to scalably make bets against informed professional traders while they sleep.

Quite ironic. The original Robin Hood took from the rich and gave to the poor. Robinhood, the app, seems to do the exact opposite: it helps the rich get richer at the expense of regular folk.

They turned Robin Hood to Robbin’ the Hood

This was always the Robin Hood play (versus being a grown up brokerage), they are simply griftmaxxing now in a "low regulatory environment". Like Coinbase, they need volume to succeed economically, not buy and hold investors. Crypto volume is down, so Coinbase revenue is down. Young people have little to no cashflow, but they have high intent to gamble in a crushing and financially nihilistic macro, which Robin Hood serves.

Well, have your seen the current size of Sherwood forest

I believe you’re confusing access with outcomes. Giving people access to markets isn’t exploitation afaic.

If you’d like to make dubious trades that’s your prerogative and who am I to stop you.

You are a member of society. Society stops people doing harmful things to themselves all the time.

This should be limited to giving advice (education, warning, explicit consent), unless there's harm to third parties.

Because, you know, certain actions and even thoughts can lead to eternal damnation in Hell, according to what a society may think. Would you prefer the society to hold you off from that?

People claim this all the time to win internet arguments but the truth is we all have a moral code.

If you see a child playing with a loaded gun, you won’t stop it?

A child is not a fully autonomous person. I would of course take the loaded gun from the child, unload it, and explain its dangers to the child.

Money, in any form, may be as dangerous as a loaded gun, trading stocks or not. Most adults are careful with money, as they are with loaded guns. The problem is that some parties may try to make trading stocks (even leveraged) look much easier and safer than it is. It's like giving somebody a real loaded gun, while making it look like a toy gun, safe even for a child. And this of course needs to be regulated: not the trading, but the disclosure. This is not a toy.

Who are you to decide that a child is not a fully autonomous person? Sounds like you're imposing a normative rule based on societally derived presuppositions of right and wrong, which is exactly the point. We're just haggling over where the line should be drawn and you think it should be drawn somewhere further back than others do, but there's no truth to be found here.

Harm to others includes cost to society in general.

I have access to a car and bottle of bourbon, but there are laws that restrict me from drinking and driving.

they don't restrict you, you can always drink and drive. you may or may not, depending on your luck, suffer the legal consequences of your actions.

tell that to the cops that’ll pull you over.

ignition interlock device market continues to grow, as some states are attempting to require them in all new cars.

And the one time an internet meme exploded a stock they literally hid the buy button from their UI. At least they have confetti animations.

This was not due to malice but instead, incompetence. They didn’t have enough cash to clear their trades.

I have ranted on here before about the SV startup mindset of “I don’t need to know anything about the industry I’m ‘disrupting’ nor do I need to play by their rules” and this was an example of that. On that day, everybody who was actually in capital markets went, “what f-ing idiots those guys are”

Especially because it will reduce the entropy that constrains the big guys from building a Dutch book (money pump) against the little guy.

I am sure there are some very happy people in the larger firms due to this news.

And not just informed professional traders -- also insiders with privileged information about world events that let them trade before the news hits. Now AI agents are going to be chasing phantom signals that look like they might be evidence of an insider's move.

I disagree, AI agents could help level the playing field. Citadel doesn't have any AI models that are better than what you or I have. Market data is more accessible than ever. As LLMs get better at trading, the difference in capability between you and a professional trader gets smaller.

Also, Claude knows about a lot of the traps that consumers can fall into: spread, execution, risk concentration, etc. -- high chance that if I tell Claude I'm thinking of going all in on AMC because some Reddit post told me to, it'll say "slow down cowboy"

Maybe if you prompt it to be highly critical of you, the user.

Otherwise it will absolutely right you out of money.

Could this be a good thing - yes

Will it be is a different thing though. And if it’s not, who exactly is accountable?

With funds and portfolio managers that run them, there’s a clear accountability model (if the fund sucks, the manager loses their job and the company loses credibility)

With AI agents doing the management, who is accountable when the fund sucks? If it’s the customer, we’ve moved accountability from someone who at least in theory, knows what they’re doing to someone who has little to no clue.

You have to be accountable for what you have the model do on your behalf. I hear what you're saying, but there are also issues with the hedge fund accountability model. There are certainly swaths of fund managers who are only there because they got lucky or had the right pedigree, and more that are better traders but never became a fund manager because they got unlucky or had other passions.

An individual investor can invest with their risk appetite on their time horizon and not be subject to Citadel's "5% draw down in a quarter and you're fired" culture which can be toxic to returns over time.

I believe that your individual ability to execute an order is constrained such that some of the difference is removed. On the other hand, the overall thesis has merits IMHO

What is the point of having a speculative market if everyone has access to the same information and capabilities? You might as well just direct deposit a proportional share of all economic growth relative to investment into every citizens account and be done with it.

That's kinda the point of total stock market ETFs lol

LOL. This is the outcome when a Product Manager sits there and says "You know, people just aren't losing enough money on sports betting and gambling apps. How can we fix this?"

Even better for America's well being will be if thousands of individual investors have identical or near identical bots for sophisticated financial institutions to exploit while they sleep.

I have no reason whatsoever to think anything could go wrong with this idea.

Is this an improvement over the full port 0dte trades you see on WSB?

Another way for retail to get themselves and their AI agent wrecked.

Will be waiting for the notice to say that 70% of users lose money to now 90% of users lose money.

"Diversify my portfolio. Lose no money."

This sounds like a great way to go bankrupt.

Yo dawg, I heard you like gambling.

Robinhood is named ironically. It's where retail joe six pack goes to lose their money to the rich.

What could possibly go wrong?

I suspect that the folks that get it right, will do nicely.

But not everyone will get it right...

Great! Now, the remaining thing we need is the ability to declare an AI agent a legal person, and then we're off for some very interesting times.

don't forget to let them vote.. "algorithms are people too"

Someone, somewhere spinning up ads telling me about Mr Average Person who made millions with this nonsense...

awesome, now you can spend your money burning tokens to enable burning your retirement

Imagine the possibilities with prompt injection.
