Kelly Criterion Other Betting Calculators VideoKelly Criterion Trading Strategy : Used by Buffett, Munger, Pabrai 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. 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. 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 bet-sizing technique which balances both risk and reward for the advantage gambler. The same principle would work for any investment with an expectation of being profitable. For the gambler/investor with average luck bankroll and a fixed bet size, the expected bankroll growth after one bet is. The Kelly Criterion is a mathematical formula that helps investors and gamblers calculate what percentage of their money they should allocate to each investment or bet. The Kelly Criterion was.
A 3, 4, 9, 10, or 11 still pay 1 to 1 and every other total loses. Then the expected bankroll growth per bet would be:. This product is maximized by Kelly betting.
Kelly betting also minimizes the expected number of bets required to double the bankroll, when bet sizing is always in proportion to the current bankroll.
The Kelly bet amount is the optimal amount for maximizing the expected bankroll growth, for the gambler with average luck. While betting more than Kelly will produce greater expected gains on a per-bet basis, the greater volatility causes long-term bankroll growth to decline compared to exact Kelly bet sizing.
Betting double Kelly results in zero expected growth. Anything greater than double Kelly results in expected bankroll decline.
What is more commonly seen is betting less than the full Kelly amount. This system will help you to diversify your portfolio efficiently, but there are many things that it can't do.
It cannot pick winning stocks for you or predict sudden market crashes although it can lighten the blow.

Taking expectations of the logarithm:. Thorp  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.
Without loss of generality, assume that investor's starting capital is equal to 1. According to the Kelly criterion one should maximize.
Thus we reduce the optimization problem to quadratic programming and the unconstrained solution is. There is also a numerical algorithm for the fractional Kelly strategies and for the optimal solution under no leverage and no short selling constraints.
Although the Kelly strategy's promise of doing better than any other strategy in the long run seems compelling, some economists have argued strenuously against it, mainly because an individual's specific investing constraints may override the desire for optimal growth rate.
Even Kelly supporters usually argue for fractional Kelly betting a fixed fraction of the amount recommended by Kelly for a variety of practical reasons, such as wishing to reduce volatility, or protecting against non-deterministic errors in their advantage edge calculations.
From Wikipedia, the free encyclopedia. Bell System Technical Journal. 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. Compare Accounts. The offers that appear in this table are from partnerships from which Investopedia receives compensation.
