What Is the Kelly Criterion? 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. 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  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. Investors often hear about the importance of diversifying and how much money they should put into each stock or sector.
These are all questions that can be applied to a money management system such as the Kelly Criterion, one of the many allocation techniques that can be used to manage money effectively.
This system is also called the Kelly strategy, Kelly formula, or Kelly bet. This article outlines how this system works and how investors use the formula to help in asset allocation and money management.
However, the gambling community got wind of it and realized its potential as an optimal betting system in horse racing.
It enabled gamblers to maximize the size of their bankroll over the long term. Today, many people use it as a general money management system for gambling as well as investing.
The Kelly Criterion strategy has been known to be popular among big investors including Berkshire Hathaway's Warren Buffet and Charlie Munger, along with legendary bond trader Bill Gross.
There are two basic components to the Kelly Criterion. 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. The most widely held criticism is that the effectiveness of this formula can be impeded by the constraints of an individual investor.
Hence, the specific constraints of these investors can override their judgment when it comes to the optimal growth rate of capital.
This constraint is a crucial factor that determines the investment decisions made by individuals regardless of the signals of the Kelly formula.
