It's sustainable with small numbers.

That is to say, 213% gains from trading $2000 on JNUG/JDST is a lot more feasible than 213% gains on $75,000,000 USD worth of AMZN calls

View on HN

Agree that it is far more likely to do that with small numbers rather than big numbers. But that is something entirely different than finding a sustainable scheme giving 10% per month returns.

Sustainable should mean that 500 readers of HN each individually managing their little $2000 nest egg ($1 million aggregate) making independent decisions should be able to collectively be sitting on $3.13 million after a year.

You don't get sustainable 213% returns without a commensurate, sustainable level of risk to go with it. But if you're able to do it sustainably with 3x ETFs, congratulations.

Why do you say that? Yes, $75M poses liquidity issues, but that doesn't mean that a smaller amount is easier. I'd wager that a smaller portfolio is harder because you can't diversify to mitigate your risk.

It's really hard to find 75m worth of buyers. You can't buy and sell as freely as you please, like you said, because of liquidity.

I can buy JDST at 9am for $60 and sell at 9:45am for $60.60. On a balance of $2000, this is an easy $20 for basically no risk, imo.

That's pretty cool that it never goes down and you don't ever buy at $60 and sell at $59.40.

Agree, if you are buying only on days where RSI is extremely low (below 30) then you can be much more confident you won't sell at a loss compared to buying when RSI is above 50
