Idk man. I had P=1 that I would have another one of these to read during my morning dump today, but my inbox is empty. I have attention to give, and no one to take it.

What If: Jack Kerouac had been born 2-3 decades later, survived psychedelics, and studied / traded the markets.

Lol, Reading SBF's opinion now is just hilarious and sad

What's EV (from SBF's tweet)?

I would think the "Kelly Criterion" is a good formula to use to size your bets. So in your first example: with these assumptions, there's a 95% chance of making +86% (0.45*80 + 0.5 * 100), and 5% of making -20%, so using the Kelly Criterion, you'd bet 469% of your portfolio (0.95/0.2 - 0.05/0.86). Does that make sense, or am I being stupid? 😂 Fits with what SBF is saying.

Expected Value. And yes the Kelly criterion is a good tool to use. Your example follows, one would have levered up and be set.

Thanks for this article Cobie. I applied your ideas to a trade idea and managed to 2x my portfolio. Applied similar thinking on whether to stay in the trade or not and got 47/53 split. Guess I'll just have to flip a coin. Cheers mate!!! Keep writing
