The first 100 periods of bets forces us to hold a counterintuitive idea in our minds. While the population as an aggregate experiences outcomes reflecting the positive expected value of the bet, the typical person does not. The increase in wealth across the aggregate population is only due to the extreme wealth of a few lucky people. How can we reconcile this expectation of loss when looking at the time average growth with the continued growth of the wealth of some people after 100 periods? It does not seem that everyone is “almost surely” on the path to ruin. Kelly’s original paper made the point that the criterion is only valid when a series of bets are made.

And “f informative post ” is the fraction of our bankroll we wish to put at stake. John Larry Kelly, Jr. was born in Corsicana, Texas on December 26, 1923. He devoted four years of his life in the US Navy as a pilot and served in the World War II. Kelly studied at the University of Texas at Austin and earned a PhD in Physics in 1953.

Your estimates of odds and edge are most likely inaccurate and off. Your objective function and utility may require a different mindset. While we often see statements indicating that a Kelly strategy will outperform all other strategies over time, the required time duration for Kelly to outperform other strategies may surprise you.
Bet Sizing Using Kelly Criterion
The fact that Black-Scholes has only one unknowable parameter makes it quite usable, more so than more complicated option pricing models. You can work backwards from the market price to solve for the implied volatility, treating it as a generalized ‘price’ for the option after factoring out things that are easily adjusted for. You can also abuse the implied volatility to account for factors outside of the idealized model. Professional gamblers don’t play pure random games for a living. They play games where they feel that knowledge/skill have some influence .

It is important to note that the formula assumes that you invest in a similar manner now than you did in the past.

It turns out that the best bet is exactly the advantage that you have in the game. To simulate that I ran a python program through a couple million people betting different percentages of their bankroll. You can download that python program, the one that generated the charts below, and the associated Excel file here. This chart shows how much money the 50th percentile person would have depending on how much they bet as a percentage of their bankroll. On the first bet, if you bet 100 dollars, you have a 50/50 chance of winning vs losing.
I look for a place where I’m wise, and they’re stupid. Last but not least, never apply the Kelly Criterion to short odds wager or all-in type of wagers. A good idea would be to implement the progression element, where you would increase or decrease your stake based on your results going forward.
