This paper shows the results of using Kelly criterion in a gamble of bidding T steps, and derives the relation of profits between using p and W/T as the winning probability in the Kelly test.dedingenfabriek.nl formula, respectively. But as always, the dots connect and your circle of competence will play a major role in determining the probabilities of outcomes. Let’s take it one step further and apply it to a stock portfolio.
