Charlie Munger: Turning $2M Into $2T

> In short, academic psychology departments are immensely more important and useful than other academic departments think. And, at the same time, the psychology departments are immensely worse than more of their inhabitants think.
In effect, much of the story is merely to illustrate that we're bad at learning from history, because we aren't very good at understanding how we think about things.
Ultimately, he's an uber rich guy who got lucky getting rich. Why should we listen to him about anything?
I read bits of the posted article. It's about what I would expect from Munger, and most of it isn't worth quoting and arguing against.
These guy are in the business of investing, not trading. A lot of people don't understand the difference and that is part of their advantage.
A better example of Buffett's obsessiveness is that he used to pick up discarded race track tickets. The overwhelming majority were no good, of course, but you might find one in a thousand where a winning ticket had been absent-mindedly discarded and you could cash in on the bet.
But, well, the fund management industry do work hard, yet have little to show for it. An old investment classic (can't remember which) put it this way: a guy new an analyst that could tell you everything you wanted to know about every railway company, except which ones to invest in.
I think many good investments rely on just a few simple arguments. For example, back in 2021 I learned that the price of Shell shares were at their lowest point for a decade or so, oil was at a low, and the US strategic oil reserves were at their lowest level since the 80's. I figured, Jeez, how much lower can then stuff go? So I bought shares. They've nearly doubled. There's no guarantees with this stuff, of course, I've made plenty of mistakes. It also requires the availability of opportunities, naturally. Sometimes my primitive monkey brain can spot them. No guarantees, there never are, but sometimes you can spot opportunities where the odds are stacked in your favour, and those are the ones you want to dabble in.

Jim Simons has mentioned explicitly about how most people underestimate the role of luck in success, and he attributes quite a bit of his success to luck.
I hope UCSB backed out of building one of these monstrosities.

Students pay several tens of thousands of dollars to go to universities these days. That's not remotely begging.

In other words the whole game of corporate planning is fairly pointless imho and merely a shell game around market growth.
There's so much in the article that fundamentally knows what the future is. The most egregious point for me was disussing Pavlov in an 1884 context. (His discovery of classical conditionings dates to 1890 and later)
Assuming a four cent profit requires assuming large inflation over the intervening time span. (It's been ~3000%). Inflation in 1884 was barely understood, and mostly treated as a devaluation of currency, not an increase in price.
Population growth to 8 billion people required modern medicine and modern agriculture at the least. (World population less than doubled over the 19th century - assuming it'd quadruple again, especially given that the Malthusian trap was a prevailing thought concept, would be an extremely bold assumption)
And so the entire pretext that you could've predicted this path kind of falls apart. We can retcon an explanation, but we can retcon an explanation for any success easily. So easily, we have a picture of a bullet-riddled plane to handily explain it.
The key to exploiting LLN is to avoid “game over” scenarios. You have to survive and stay in the game in order for LLN to converge.
If let’s say your expectation of winning in the long run is 0.7, you’ll only achieve this if you don’t get wiped out anywhere in the process (if you do your expectation drops to 0 immediately).
I have often wondered why the price of the option does not naturally find a level that exactly cancels out the trade?
Edit: Sounds too challenging - I am interested in your take on risk management, please expand. Esp with red to why options are priced at a level where they make a profit? (my perhaps limited understanding of options is I am betting A will go up 10% but if A goes down 5% I can buy an option to purchase A at the lower price. My instinct is at some point there is always a losing side. Why enter?
Kind of. Fundamentally risk management comes down to bankroll management. And one workable general approach is the Kelly criterion[1] or something like it. However, unlike casino games, with options we don't know the true odds and have to estimate them in most cases. And there are other risks like theta, which is how all else being equal an option loses premium value as expiration approaches. Therefore we can't just use Kelly directly. A trivially simple strategy that is suboptimal, but is good enough for learning is to never risk more than 1% of your trading bankroll[2]. The end result is that as you make winning bets your bet size increases and as you make losing bets your bet size decreases. Remember your goal at this level of knowledge is hands on learning with some skin in the game to sharpen your attention.
In the prior paragraph the trivial basic risk management strategy is "never risk" more than 1%. The reason I say never risk rather than never bet is because when trading options you can lose more than you bet! In fact you can potentially go to zero. A simple example is selling an uncovered call, that is to say selling someone the right to buy some multiple of 100 shares of a stock at a fixed price while not actually owning the stock to sell to them if they exercise the contract. Therefore, if the contract is exercised you have to go and buy however many shares are needed to cover the call. Since there is no limit to how much higher the market price can be than the call's strike price, you can lose an unbounded amount of money from a bet that actually increased your cash on hand when you entered it. Most (all?) trading platforms have some notion of options levels. I highly advise not requesting the level that lets you make such bets. I personally don't see any good point to them[3] and for a slightly increase in premium you can make very similar bets without the unlimited downside by using spreads.
If you are unspeakably unfortunate or otherwise consistently make losing bets, then even solid risk management can result in your ruin. However, it will be a slow process and hopefully somewhere before disaster you will conclude that trading derivatives isn't where your gifts lie and preserve what remains of your capital.
> I have often wondered why the price of the option does not naturally find a level that exactly cancels out the trade?
Options markets aren't perfectly efficient. Furthermore, the typical leverage is 100:1, which magnifies even small pricing inefficiencies. In fact, there isn't even agreement on how to price options at all. The Black-Scholes model[4] is just one popular model and many traders think it has problems.
> My instinct is at some point there is always a losing side. Why enter?
Yes, derivatives trading isn't investment, and there is always (usually?) a winner and a loser for every trade. However, there are market participants that make trades that set out to make a loss. For example, A trader may need to execute a hedging strategy and one leg of it will lose money if his primary trade goes as he hopes. Nevertheless, the opportunity remains to potentially be the counterparty on hedging leg. This is a pretty complicated area and I don't pretend to have a deep understanding of it, but if you dig in you'll find plenty of discussion.
There are also market participants who are just making bad trades. When you start you'll probably be one of them, which is why I emphasize risk management. Their counterparties also have a good opportunity to profit.

[2] And that bankroll itself should be less than your total financial net worth (IE paper assets like cash and stocks and so on, not real estate). Don't bet your emergency fund and so on. How much less depend on your own circumstances and is more a general matter of savings allocation than anything derivatives trading specific.
[3] But as I said I'm not an expert, just a dabbler who did OK. Perhaps some sufficiently advanced trader can come up with a good reason to make such a bet that isn't just based on hubris and wishful thinking.
Also known as "it's easy to become a rich man, if you start out as a rich man".
Realizing a positive real return is not very hard - just buy the index or some real estate. If you start with a large amount of capital, you can simply watch it multiply, and, for the adventurous, maybe risk some of it into more speculative deals.
If you start out with just the human capital of your hands and brain, any reasonable rate of return will be squashed by living expenses and basic quality of life, dependents etc. You will need many decades to build enough wealth using the same methods a rich man uses, and by that time your own human capital starts to depreciate and you are forced to move to a capital conservation strategy.
So, to make it big as a poor person, you always have to take on crazy risks that the rich never would and/or be exceptionally lucky, or be extraordinarily talented and hardworking - to an statistically implausible degree - so as to make your starting human capital much more valuable.
You will always find the rags to riches story presented as a tale of hard work and determination, but rarely will any "self made billionaire" acknowledge their immense luck. The entire VC space is basically an attempt from capital owners to cash in on this statistically rare phenomenon, by hedging their bets on the destinies of many many people attempting to make it big.
Maybe you meant "and possibly", since otherwise the 'or' there detracts from the point I think you're trying to make (that ludicrous amounts of wealth requires luck regardless of what talent, skill, or determination you bring).
You have 15 doubles between 1884 and 2034.
So you get 2^10 * 2,000,000 or 2,048,000,000 - just over 2 trillion dollars.
I read through parts of the article - I have no idea what point is attempting to be made. It all rambles quite a bit.
"""This brings me, at last, to the main purpose of my talk. Large educational implications exist, if my answer to Glotz’s problem is roughly right and you make one more assumption I believe true – that most Ph.D. educators, even psychology professors and business school deans, would not have given the same simple answer I did. And, if I am right in these two ways, this would indicate that our civilization now keeps in place a great many educators who can’t satisfactorily explain Coca-Cola, even in retrospect, and even after watching it closely all their lives. This is not a satisfactory state of affairs.
Moreover – and this result is even more extreme – the brilliant and effect executives who, surrounded by business school and law school graduates, have run the Coca-Cola company with glorious success in recent years, also did not understand elementary psychology well enough to predict and avoid the “New Coke” fiasco, which dangerously threatened their company. That people so talented, surrounded by professional advisers from the best universities, should thus demonstrate a huge gap in their education is also not a satisfactory state of affairs."""
That is not true at all. "Percentages are reversible" means that 30% of 50 is the same as 50% of 30, so 15. It does not mean that anywhere you see a percent related to another number, you can just switch them around.
Easy counterexamples:
At 100% annual interest, you double your money every 1 year. At 1% annual interest, you double your money every 70 years.
At 41% annual interest, you double your money every 2 years. At 2% annual interest, you double your money every 35 years.
100% interest (compounded monthly) doubles at about 0.75 years, and 0.75 interest doubles at around 100 years.
41% interest doubles at around 1.75 years, and 1.75 interest doubles at around 41 years
When talking about stock market returns, people are talking about year-over-year returns. There is no "compounded monthly"; 41% interest "compounded monthly" is actually 49.7% interest. Everyone would call that 49.7%, except credit card commercials that are trying to trick you.
The point is that GP presented the %-switching thing like a rule, but it's not. They've confused how that rule is applied.
Edit: I tried compounding every second. The rule works exactly. e is just such a magic number that continuous compounding is exactly the point at which this rule becomes true. So the more often you compound, the better this rule is. Wild. I still don't recommend using it for annual percentages.
Glotz wants to use a name that has somehow charmed him: Coca-Cola.
Just why was Glotz charmed by that name? Ctrl-F "cocaine" - 0 hits
Oh. Charlie is telling a just so story that doesn't comport with the facts. Confederate Colonel John Pemberton, wounded in the American Civil War
and addicted to morphine, also had a medical degree and began a quest
to find a substitute for the problematic drug.
Like sure - a cocaine tonic sounds just the thing to help an alcoholic doctor kick a heroin habit. Pemberton claiming it a cure for many diseases,
including morphine addiction, indigestion, nerve disorders, headaches,
and impotence.
Oh yeah, baby! Dude was selling coca-wine, and then temperance kicked in and he had to de-wine the wine. Here's Munger talking about adding colour: For similar Pavlovian reasons, it will be wise to have
our beverage look pretty much like wine, instead of sugared water.
And so we will artificially color our beverage if it comes out clear.
Lol, no. The color needed to emulate wine because his current users were used to a wine cocaine tonic. Got the bring the exiting user-base along.The technical term for Munger's story is bullshit. He doesn't consider it a lie, because the facts are unimportant to his story.
Honestly, reading this diminished my opinion of him. To talk the whole time about pavlovian and operant conditioning without once mentioning drug tolerance and withdrawal discomfort is just beyond. He can't be that stupid, so I must suspect dishonest motive. Or even worse: obscurantic Straussianism.

Sadly, more often than not, someone else has to do it for them.
Yes, in general, we are not great at learning from history. How does blending academic psychology with other departments change that? Like how will that information disseminate *through/permeate society?
“This brings me, at last, to the main purpose of my talk. Large educational implications exist, if my answer to Glotz’s problem is roughly right and you make one more assumption I believe true – that most Ph.D. educators, even psychology professors and business school deans, would not have given the same simple answer I did.

Yep.
As a former academic (left precisely due to this sort of absurdity), I largely agree with his view.
If 100 million people flipped 20 coins, 95 would get 20 heads.
There are approximately 25M millionaires in the US.
2^20 = 1048576
So roughly 1 in 1 million.
You're off by 100x.
Now suppose of all the crazy investing philosophies in existence, you learn that all N greatest investors (or "N luckiest coin flippers" according to you), suppose you learn all of them have the exact same investing philosophy.
Would this make you reconsider whether your "investing is coin flipping" model is a useful model?
"The Superinvestors of Graham-and-Doddsville"

You can just carry any non-100% gain/loss "swimlane" as a game still-in-progress. Eventually on larger time scale, puchasing power adjusted or not, a swimlane of an investment will certainly hit one of those outcomes.
The outcome is a function of time but a large number of swimlanes guarantees that you can sample any time and observe the same distribution of settled outcomes. You can reasonably assume that the probability of transition from unsettled to settled state at any time is constant. You could model it as markov process. In fact there are many economic agent models doing something like this (OLG models where generations of economic agents overlap in time as child/worker/retiree). Even though these models make sense only on generational scale, with enough agents you can see the micro-structure being consistent in smaller time scales by "ticking" or sampling at smaller time steps the markov process.
The spending power issue could be ignored as "without loss of generality" in most cases or the thesis could be restated in terms of something that preserves purchasing power as part of the coin toss game.
Investment returns mean-revert only if allowed to by policy. Policy can override economic forces for very long generational time scales, thus making it still relevant for individuals.
And I personally don't agree with (or don't understand) these models being used for micro-structure analysis, but I think macro-level interpretations such as wealth distribution may be valid.
Great! Then you will have no problem accepting the following offer: you give me $1000 today, I will give you an arbitrary amount of money that you get to specify (so it has to be computable -- no busy beavers allowed). The catch is that I get to specify when the payout happens (of course with the same proviso: the payout will happen after a computable amount of time).
What a surprise.
> this is the game that represents the economic reality
No, it isn't. Economic reality is nothing like flipping coins, neither for individuals, nor in the aggregate, except insofar as both contain a random element.
> it is still a markov process
So what? Saying "it's a Markov process" is simply making the observation that there is a random element. Yes, flipping coins has a random element, and yes, the market has a random element. It does not follow that flipping coins is a good model of the market. On this logic, coin-flipping would be a "good model" of any non-deterministic process.
The interesting thing about Markov processes is not that they contain random elements. The interesting thing about Markov processes is that you can make reliable predictions about some of them despite the fact that they contain random elements. But coin-flipping is not one of those processes about which interesting predictions can be made. The economy is.
Really? Population of the US is like 350M. Is 7% of US population millionaires? Like, one of out every 14 people out there? I guess that's believable but counter-intuitive.
"The median household wealth in 2021 was $166,900. The 10th percentile of household wealth was zero dollars, meaning 1 in 10 households had wealth of zero dollars or less. The 90th percentile of household wealth was $1,623,000, meaning 1 in 10 households had wealth exceeding $1.6 million."
If they were starting out with $2 million and betting it on a coin flip, they would owe 37% income tax on the winnings of each flip.
And try finding someone to bet you $1 trillion on a coin flip.
Charlie Munger's strategy was not to start out with $2 million and bet it with a 0.0001% chance of winning $2 trillion and a 99.9999% chance of losing it all.
Some people invest money out of each paycheck, study how to best allocate that money between the investment options available to them, do that for many decades, and become millionaires. Some people buy a $2 lottery ticket and become millionaires that day. They both just got lucky, am I right?
It's important not to "diagnose" people. But these patterns are real and shed light on logics we operate with.
A little understanding goes a long way.
It makes sense that our brain, like any device class, has common patterns of high/low performance and failure.
I don't know where in education exposure to practical psychology makes sense. But a formal psychology class is too late, too narrow, too short, and too segregated a context: as the article points out.
We don't want to interrupt children's development with psychological concepts they are not ready for. But it would be nice to understand each other better, earlier.
That is an interesting education problem.
--
A related thought. There are so many areas of vitally useful knowledge, but turning each area into a formal subject isn't possible or necessary.
All that is needed for many great ideas is exposure.
Many geniuses' benefited as children from frequent informal discussions with knowledgable curious persons.
Perhaps a daily open discussion lunch hour could provide that exposure. Where all manner of subjects are discussed, and all kinds of questions are welcome.
It could be the easiest most impactful class of the day.

First, the price of a 6.5 fl. oz. bottle of Coca-Cola was set at 5¢ in the 1880s and remained 5¢ through the 1890s, the 1900s, the 1910s, the 1920s … all the way until the 1950s when the price was finally raised. The dynamics that led to this remarkable phenomenon is described in a Planet Money podcast [1] and on Wikipedia [2].
Second, “starting in Atlanta, then succeeding in the rest of the United States, then rapidly succeeding with our new beverage all over the world” is much easier said than done. Coca-Cola somehow hit this jackpot, but Munger himself would cite See’s Candies as a counterexample of a brand that, for whatever reason, does not travel as successfully from its place of origin.
[1]: https://www.npr.org/transcripts/456410327
[2]: https://en.wikipedia.org/wiki/Fixed_price_of_Coca-Cola_from_...
No, that's explicitly mentioned in the story:
> And thereafter the real Coca-Cola company did lose half its trademark and did grant perpetual bottling franchises at fixed syrup prices. And some of the bottlers were not very effective and couldn’t easily be changed. And the real Coca-Cola company, with this system, did lose much pricing control that would have improved results, had it been retained.
Irony.
But according to the link below, "3.1% of all beverages consumed around the world are Coca-Cola products" :
https://www.businessinsider.com/facts-about-coca-cola-2011-6
This is supported as follows:
> Of the 55 billion servings of all kinds of beverages drunk each day (other than water), 1.7 billion are Coca-Cola trademarked/licensed drinks.
> Source: Coca-Cola 2011 SEC Filings, Coca-Cola
So that 3.1% apparently excludes water and would be even smaller if water is counted.
That doesn't work because look at all the companies selling generic cheap soft drinks, competing for the lowest cost, and not being anywhere near 150 years old or $2TN. Munger's talk is about what Coca-Cola would need to do over and above ordinary "selling a soft drink" to achieve such a thing.
The important points to make, are that it's far more important to maneuver oneself into a position where you can see the landscape clearly, deliver the power to make moves, and then just use uncluttered thinking to chose those moves but chose them you must as the more moves you make, the faster you learn. As opposed to lingering in the ivory tower devising ever more ingenious strategies to excuse weak execution.
Charles Munger is such a smart man in many ways, and it is sad to see his thinking get muddy in his old age. I am surprised he falls for 'Survivorship Bias` in his own thinking.
The funds were intended to be loaned to aspiring tradesmen, who would repay their loans with interest over ten years. The two cities would receive some of the funds for public works after 100 years and the balance after 200 years. Both cities failed to manage the funds as Franklin intended.
From Meyer's book, I learned more about Benjamin Franklin's life, about the challenges of fund management, and about the difficulty of controlling events from beyond the grave.
