The Investment Strategy of Kelly Criterion Based on the Stock Price Following Lognormal Distribution
Abstract:Based on the idea of centralized investment strategy, we combined the stock price following lognormal distribution with Kelly Criterion, so that it can be used in stock investment more effectively. In order to achieve the fastest wealth growth rate, we deduced the mathematical relationship between the optimal investment proportion and the expectation return and standard deviation of a stock.
