Note that there is a misprint in the formula for approximating average growth rate on p 2nd edition and the approximation also assumes that your advantage is small.

There is a short list of corrections which can be found through John Haigh's web page. Note that although the Kelly Criterion provides an upper bound on the amount that should be risked, there are sound arguments for risking less.

In particular, the Kelly fraction assumes an infinitely long sequence of wagers — but in the long run we are all dead. There's an interesting discussion of this not aimed at a mathematical reader in Part 4 of the book Fortune's Formula which gives some of the history of the Kelly criterion, along with some of its notable successes and failures.

Jeffrey Ma was one of the members of the MIT Blackjack Team, a team which developed a system based on the Kelly criterion, card counting, and team play to beat casinos at Blackjack.

He has written an interesting book The House Advantage , which examines what he learned about managing risk from playing blackjack. He also covers some of the measures put in place by casinos to prevent the team winning!

Heuristic proofs of the Kelly criterion are straightforward. This gives:. For a rigorous and general proof, see Kelly's original paper [1] or some of the other references listed below.

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. Petersburg paradox.

An English-language translation of the Bernoulli article was not published until , [14] but the work was well-known among mathematicians and economists.

Kelly's criterion may be generalized [15] on gambling on many mutually exclusive outcomes, such as in horse races.

Suppose there are several mutually exclusive outcomes. The algorithm for the optimal set of outcomes consists of four steps. One may prove [15] that.

The binary growth exponent is. In this case it must be that. In mathematical finance, a portfolio is called growth optimal if security weights maximize the expected geometric growth rate which is equivalent to maximizing log wealth.

Computations of growth optimal portfolios can suffer tremendous garbage in, garbage out problems. Ex-post performance of a supposed growth optimal portfolio may differ fantastically with the ex-ante prediction if portfolio weights are largely driven by estimation error.

Dealing with parameter uncertainty and estimation error is a large topic in portfolio theory. The second-order Taylor polynomial can be used as a good approximation of the main criterion.

Primarily, it is useful for stock investment, where the fraction devoted to investment is based on simple characteristics that can be easily estimated from existing historical data — expected value and variance.

This approximation leads to results that are robust and offer similar results as the original criterion. Considering a single asset stock, index fund, etc.

Taking expectations of the logarithm:. Thorp [13] arrived at the same result but through a different derivation. Confusing this is a common mistake made by websites and articles talking about the Kelly Criterion.

Kelly Criterion: Bankroll Size for Blackjack Card Counting The algorithm for the optimal set of outcomes consists of four steps. Suppose you're horse racing, and you think that 2 of the horses are priced wrong, how much should you bet on each? Note that there is a misprint in the formula for approximating average growth rate on p 2nd edition and the approximation also assumes that your advantage is small. Investors can put Kelly's system to use by following these simple steps:. Worse yet, mathematicians have a number of terms they use, and none of them are exactly what gamblers need.

We can certainly see why the Kelly Criterion Katana Forest strategy is so popular. In a sports betting sense, it can therefore be used to calculate how much you should stake on any wager you place. The other is that the Kelly formula leads to extreme volatility, and you should underbet to limit the chance of being badly down for unacceptably long stretches. Worse yet, mathematicians have a number of terms they use, and none of them are exactly what gamblers need. Sollten Sie damit daneben liegen, wird die gesamte Formel unbrauchbar und rät Ihnen dazu entweder zu viel oder zu wenig Anteile Ihres Wettkontos einzusetzen.

A positive percentage implies an edge in favour of your bankroll, so your funds grow exponentially. You can also test the criterion for different values in this online sheet by using the code below.

Ultimately the Kelly Criterion offers a distinct advantage over other staking methods such as Fibonacci and Arbitrage methods as there is a lower risk.

However, it does require precise calculation of the likelihood of an event outcome, and discipline of this method will not provide explosive growth of your bankroll.

For even-money bets i. In this case, as is proved in the next section, the Kelly criterion turns out to be the relatively simple expression.

Thus, using too much margin is not a good investment strategy when the cost of capital is high, even when the opportunity appears promising.
