Now we will simplify the example to two successive bets, one win and one loss. Thus considering two bets with opposing outcomes provides a reasonable estimate of the Geometric Growth Rate of the investment. At small bet sizes, the profit grows with leverage in an almost one-to-one relationship.

But as leverage increases, the marginal profit shrinks and eventually turns negative. Greater than 3x leverage actually loses money.

Remember that's NGD not NdGT. Notice how the Negative Geometric Drag is the square of the bet size leverage.

At lower levels of leverage, the edge is the dominant force and the NGD is negligible. However, as leverage grows, the NGD becomes larger and eventually overwhelms our edge. Now the components of Edge, NGD and Profit are broken out individually. This is the point of maximum profit leverage 1.

To state this another way, using this level of leverage would maximize the Geometric Growth Rate of your wealth over the course of many bets, investments or trades. If we ran this experiment over 1, bets as we did in the Blackjack example, 1. The Kelly Criterion is a formula which accepts known probabilities and payoffs as inputs and outputs the proportion of total wealth to bet in order to achieve the maximum growth rate.

the ratio of the amount we stand to win to the amount we stand to lose. We can then plug these values into the formula:. Kelly says to place a bet with a maximum loss of 8. This is exactly the value that we found earlier.

What about the Blackjack example? Revisiting the graphs and charts above, we can see that Kelly correctly calculated the optimal bet for both scenarios.

The Y-axis represents the geometric growth rate, the X-axis represents leverage, and the Kelly-optimal bet lies at the highest point on the curve. In every field of application the general shape of the graph will be the same.

Kelly represents the limit for the range of rational bets. It is the largest bet that could still be rational assuming no value is placed on risk. Betting even one penny more than Kelly would bring increased risk, increased variance and decreased profit.

As the bet size approaches the Kelly-optimal point, the ratio of additional risk to additional profit goes to infinity. Eventually you would have to risk an additional one billion dollars to earn one more cent of expected profit. Most people assign a negative value to risk. The first amendment accounts for the fact that the probabilities and payoffs used in the formula are only estimates.

The true probabilities and payoffs are hidden, and 9 times out of 10, reality will be less profitable than our estimates. When investing in an uncertain world, conservative assumptions are closer to reality than expectations.

The second amendment results from the observation that a bet sized at 0. Furthermore, betting fractions of the Kelly-optimal value limits the probability of drawdowns the amount by which our net worth declines below the highest value achieved so far by an exponential factor.

Here is a flow chart for how to approach sizing which incorporates these observations. Remember to constantly reassess all your risks and expectations:. For professional investors - those who manage money for clients - the optimal level of risk is even lower.

For money managers, slow and steady is the name of the game. The Kelly Criterion is a useful tool for assessing the qualitative shape of risk versus reward and understanding boundaries of what is rational.

Although it is limited by the exclusion of risk pricing, Kelly can be an excellent tool in the wider arsenal of a quantitative trader. Additionally it provides efficient estimations of drawdowns, variance and geometric growth rate. For further reading, here are two excellent books covering the history of markets and the Kelly Criterion:.

This two-part series will give a framework for thinking about risk and sizing. Part I: Simple mental models and a single-asset application of the Kelly criterion. Part II: Multiple assets, correlation and extreme tail risk.

Covel- Put another way: A trader with mediocre strategy and a great risk model will become fairly successful. A Simple Example Imagine a betting opportunity which offers positive expected value with known payouts and probabilities.

Unlike gambling, there is no truly objective way to calculate the probability that an investment will have a positive return.

Most investors using the Kelly Criterion try to estimate this value based on their historical trades: simply check a spreadsheet of your last 50 or 60 trades available through your broker and count how many of them had positive returns.

In order to enter odds into the Kelly Criterion, one first needs to determine W, the probability of a favorable return, and R, the size of the average win divided by the size of the average loss. For investing purposes, the easiest way to estimate these percentages is from the investor's recent investment returns.

These figures are then entered into the formula. While there are many investors who integrate the Kelly Criterion into successful moneymaking strategies, it is not foolproof and can lead to unexpected losses. Many investors have specific investment goals, such as saving for retirement, that are not well-served by seeking optimal returns.

Some economists have argued that these constraints make the formula less suitable for many investors. The Black-Scholes Model, Kelly Criterion, and the Kalman Filter are all mathematical systems that can be used to estimate investment returns when some key variables depend on unknown probabilities.

The Black-Scholes model is used to calculate the theoretical value of options contracts, based upon their time to maturity and other factors. The Kelly Criterion is used to determine the optimal size of an investment, based on the probability and expected size of a win or loss. The Kalman Filter is used to estimate the value of unknown variables in a dynamic state, where statistical noise and uncertainties make precise measurements impossible.

While some believers in the Kelly Criterion will use the formula as described, there are also drawbacks to placing a very large portion of one's portfolio in a single asset.
