Value is, of course, subjective in sports betting terms, as different people will have different views on the probability of any particular wager winning.

The Kelly Criterion will help you avoid doing that. Your preferred bookmaker is offering the following odds. The required calculation would be as follows.

As you can see, the formula has returned a negative value. We can certainly see why the Kelly Criterion betting strategy is so popular.

It clearly makes sense to stake higher amounts, relative to your bankroll, on good value wagers. Any technique that can help you to do that must have some merit.

The Kelly Criterion also takes the size of your bankroll into consideration, which is another advantage. With that being said, any staking plan you choose to use should be based primarily on the amount of money you have to bet with.

This is a fundamental principle of bankroll management. In fact, this is probably the biggest advantage of the Kelly Criterion. Staking more when the theoretical value is high and staking less when the theoretical value is low, should maximize profits in the long run while reducing the chance of going bust.

This serves as a useful warning to avoid such wagers. There are two main disadvantages of the Kelly Criterion. The strategy does nothing to help you find profitable betting opportunities, which is disappointing.

The second disadvantage of the strategy is that it could be considered overly aggressive. This is a very high percentage to risk under any circumstances.

A lot of bettors use what is known as a fractional Kelly strategy, where they bet a fixed fraction of the suggested stake.

This can be any fraction, but half is common. When it comes to what bettors and betting experts think about the Kelly Criterion, their views seem to be split from one extreme to the other.

Many people firmly believe that the strategy is extremely useful for calculating the optimal stakes to place, while others believe it serves very little purpose at all.

Some even consider it to be completely useless. We are among those who see both sides of the argument. It clearly makes a lot of sense to stake more money on good value wagers and the Kelly Criterion can help bettors to do this with some degree of regularity.

In our view, the Kelly Criterion has limited use as a betting strategy. We strongly recommend using a staking plan and practicing good bankroll management when betting on sports : the Kelly Criterion is a viable option for this.

Key Takeaways Although used for investing and other applications, the Kelly Criterion formula was originally presented as a system for gambling on horse races.

The formula is used to determine the optimal amount of money to put into a single trade or bet. Some argue that an individual investor's constraints can affect the formula's usefulness.

Related Terms Enterprise Value — EV Enterprise value EV is a measure of a company's total value, often used as a comprehensive alternative to equity market capitalization.

EV includes in its calculation the market capitalization of a company but also short-term and long-term debt as well as any cash on the company's balance sheet.

Kelly did not, of course, use those precise words — the paper being written in terms of an imaginary scenario involving bookies, noisy telephone lines, and wiretaps so that it could be published by the prestigious Bell System Technical journal.

Assuming that your criterion is the same as Kelly's criterion — maximizing the long term growth rate of your fortune — the answer Kelly gives is to stake the fraction of your gambling or investment bankroll which exactly equals your advantage.

The form below allows you to determine what that amount is. Unfortunately it is now defunct, and only contains adverts for an online casino.

However, you can find much of the content through the Wayback Machine archive. If this link breaks — as it has done several time since this page was written — try searching for the article title.

We based the above calculations on the description given in the book Taking Chances: Winning With Probability by John Haigh, which is an excellent introduction to the mathematics of probability.

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.

The Kelly bet size is found by maximizing the expected value of the logarithm of wealth, which is equivalent to maximizing the expected geometric growth rate.

The Kelly Criterion is to bet a predetermined fraction of assets, and it can seem counterintuitive. It was described by J. Kelly, Jr , a researcher at Bell Labs , in For an even money bet, the Kelly criterion computes the wager size percentage by multiplying the percent chance to win by two, then subtracting one.

In recent years, Kelly-style analysis has become a part of mainstream investment theory [5] and the claim has been made that well-known successful investors including Warren Buffett [6] and Bill Gross [7] use Kelly methods.

William Poundstone wrote an extensive popular account of the history of Kelly betting. The behavior of the test subjects was far from optimal:.

If losing, the size of the next bet gets cut; if winning, the stake increases. For simple bets with two outcomes, one involving losing the entire amount bet, and the other involving winning the bet amount multiplied by the payoff odds , the Kelly bet is:.

If the gambler has zero edge, i. There is no explicit anti-red bet offered with comparable odds in roulette, so the best a Kelly gambler can do is bet nothing.

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.

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.
