What is Kelly Criterion?
The Kelly Criterion is a mathematical formula that helps determine the optimal size of a series of bets to maximize long-term growth while managing risk. It was developed by John Kelly at Bell Labs in 1956.
The formula balances the potential for growth against the risk of loss, helping you find the sweet spot between betting too much (increasing risk of ruin) and too little (missing growth opportunities).
