The Kelly bet size is found by maximizing the expected value of the logarithm of wealth, which is equivalent to maximizing the expected geometric growth rate. The Kelly Criterion is to bet a predetermined fraction of assets, and it can seem counterintuitive. It was described by J. L. Kelly Jr, a researcher at Bell Labs, in 1956. For an even money bet, the Kelly criterion computes the wager size percentage by multiplying the percent chance to win by two, then subtracting one. So, for a bet with a 70% chance to win the optimal wager size is 40% of available funds. The practical use of the formula has been demonstrated for gambling and the same idea was used to explain diversification in investment management. In the 2000s, Kelly-style analysis became a part of mainstream investment theory and the claim has been made that well-known successful investors including Warren Buffett and Bill Gross use Kelly methods. William Poundstone wrote an extensive popular account of the history of Kelly betting." - Wikipedia ( ## Kelly Criterion Calculator Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource114/v4/3c/cc/ed/3ccced56-f46d-7da9-1dfc-12d786b106b0/2dd71df7-e23a-465b-8a12-8ba486798131_Simulator_Screen_Shot_-_iPhone_12_Pro_Max_-_2021-03-10_at_13.21.29.png/1284x2778.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource114/v4/d3/b8/c4/d3b8c4d0-6a73-036c-82ec-7d23abf07e68/3fe76699-c049-49f9-a027-739d364e9328_Simulator_Screen_Shot_-_iPhone_12_Pro_Max_-_2021-03-10_at_13.21.12.png/1284x2778.png) ## Kelly Criterion Calculator Rating Breakdown in United States - 5 stars: 2 (50%) - 4 stars: 0 (0%) - 3 stars: 0 (0%) - 2 stars: 2 (50%) - 1 stars: 0 (0%) ## Kelly Criterion Calculator Reviews in United States ### **--- "lacks explanations for user variables" Up front, I am a novice, so maybe this app is targeted to a more learned user, but to make this more helpful for everyone interested, it would be nice to understand what the user variables are.
