We often hear about the importance of diversifying, but perhaps it's easier said than done. How much money do we put in each stock? When do we buy or sell those stocks? These are all questions that can be answered by defining a money management system. Here we look at the Kelly Criterion , one of the many techniques that can be used to manage your money effectively. Soon after the method was published as " A New Interpretation Of Information Rate " , 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 not only gambling but also investing. The Basics There are two basic components to the Kelly Criterion: Putting It to Use Kelly's system can be put to use by following these simple steps:.
Interpreting the Results 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. This system, in essence, lets you know how much you should diversify. The system does require some common sense, however. Allocating any more than this is carries far more risk than most people should be taking.
This system is based on pure mathematics. However, some people may question whether this math originally developed for telephones is actually effective in the stock market or gambling arenas. By showing the simulated growth of a given account based on pure mathematics, an equity chart can demonstrate the effectiveness of this system.
In other words, the two variables must be entered correctly, and it must be assumed that the investor is able to maintain such performance. Here is an example:. Here we see the activity in 50 simulated trading accounts by means of an equity curve. The average amount won is the same as the average amount lost. The result is a positive return in the long run for all traders notice some short-term downside, however. Bars represent the time between trades or trading system outputs.
In probability theory and intertemporal portfolio choice , the Kelly criterion , Kelly strategy , Kelly formula , or Kelly bet is a formula used to determine the optimal size of a series of bets in order to maximise the logarithm of wealth.
In most gambling scenarios, and some investing scenarios under some simplifying assumptions, the Kelly strategy will do better than any essentially different strategy in the long run that is, over a span of time in which the observed fraction of bets that are successful equals the probability that any given bet will be successful. It was described by J. Kelly, Jr , a researcher at Bell Labs , in The Kelly Criterion is to bet a predetermined fraction of assets and can be counterintuitive.
Behavior was far from optimal. If losing, the size of the bet gets cut; if winning, the stake increases. 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.
In recent years, Kelly has become a part of mainstream investment theory  and the claim has been made that well-known successful investors including Warren Buffett  and Bill Gross  use Kelly methods. William Poundstone wrote an extensive popular account of the history of Kelly betting. 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.
