(Optimal Fraction). Rooted in John Kelly’s 1956 Kelly Criterion—which was designed for maximizing capital growth in gambling and information theory—Vince adapted and expanded this math specifically for the asymmetric payoffs of the futures, options, and stock markets. The Problem with the Standard Kelly Criterion The classic Kelly Criterion formula is elegant but limited:
