Money Management with Fractional Kelly Criterion – Trading as a Business (Part 8 of 8) The Kelly criterion is a formula used in estimating the growth of capital, it also calculates the expected value of wealth over a long period of time. The Kelly criterion was developed in by John L. Kelly, Jr and since then has been a strategy used in betting to determine the amount individuals should stake. Because the Kelly Criterion seeks to calculate the optimum stake for any value bet so as to maximise that value as well as maximise the growth of your betting bankroll. In other words, the Kelly Criterion takes into account both the size of your advantage (I.e the value available) and the size of your bankroll, so as to minimise risk and maximise your advantage. In probability theory and intertemporal portfolio choice, the Kelly criterion (or Kelly strategy or Kelly bet), also known as the scientific gambling method, is a formula for bet sizing that leads almost surely to higher wealth compared to any other strategy in the long run (i.e. approaching the limit as the number of bets goes to infinity). The Kelly Criterion is a useful tool for assessing the qualitative shape of risk versus reward and understanding boundaries of what is rational. Although it is limited by the exclusion of risk pricing, Kelly can be an excellent tool in the wider arsenal of a quantitative trader. The Kelly criterion is a mathematical formula relating to the long-term growth of capital developed by John L. Kelly, Jr. The formula was developed by Kelly while working at AT&T's Bell.

Kelly, Jr in , the Kelly criterion was applied in the betting world as a strategy to determine the probability of winning and the maximum growth of capital over a period of time.
Later on, the theory was applied to investing, it was used for portfolio selection in order to maximise wealth over a period of time.
The Kelly criterion tells an investor how much to stake in a trade or bet. The first is the win probability or the probability that any given trade will return a positive amount.
This ratio is the total positive trade amounts divided by the total negative trade amounts. These two factors are then put into Kelly's equation which is:.
Gamblers can use the Kelly criterion to help optimize the size of their bets. Investors can use it to determine how much of their portfolio should be allocated to each investment.
Investors can put Kelly's system to use by following these simple steps:. The percentage a number less than one that the equation produces represents the size of the positions you should be taking.
For example, if the Kelly percentage is 0. The portion of bankroll to bet is 0. Example 2: A casino in town is offering a 5X points promotion in video poker.
So at 5X, the slot club pays 1. After the slot club points, the return is By the way, this exact promotion is going on at the Wynn as I write this, for September 2 and 3, The advantage is 0.
The optimal Kelly wager is 0. Following is the exact math of example 3. Let x be optimal Kelly bet, with a bankroll of 1 before the bet.
Probability of winning. The Kelly criterion returned a value of Some corrections have been published. The resulting wealth will be:.
After the same series of wins and losses as the Kelly bettor, they will have:. This illustrates that Kelly has both a deterministic and a stochastic component.
If one knows K and N and wishes to pick a constant fraction of wealth to bet each time otherwise one could cheat and, for example, bet zero after the K th win knowing that the rest of the bets will lose , one will end up with the most money if one bets:.
The heuristic proof for the general case proceeds as follows. Edward O. Thorp provided a more detailed discussion of this formula for the general case.
In practice, this is a matter of playing the same game over and over, where the probability of winning and the payoff odds are always the same.
In a article, Daniel Bernoulli suggested that, when one has a choice of bets or investments, one should choose that with the highest geometric mean of outcomes.
This is mathematically equivalent to the Kelly criterion, although the motivation is entirely different Bernoulli wanted to resolve the St.
More recently, the strategy has seen a renaissance, in response to claims legendary investors Warren Buffet and Bill Gross use a variant of the Kelly criterion.
The formula is used by investors who want to trade with the objective of growing capital, and it assumes that the investor will reinvest profits and put them at risk for future trades.
The goal of the formula is to determine the optimal amount to put into any one trade. The Kelly Criterion formula is not without its share of skepticism.
Although the Kelly strategy's promise of outperforming any other strategy, in the long run, looks compelling, some economists have argued strenuously against it—primarily because an individual's specific investing constraints may override the desire for optimal growth rate.
In reality, an investor's constraints, whether self-imposed or not, are a significant factor in decision-making capability.
