Re: Kelly Formula Assuming this wikipedia page is the correct description of the kelly formula, it does not look overly complicated or difficult to program into Excel.
As simple as the formula appears: Is this the correct formula? If it is correct, what difficulty do you have programming that formula in Excel?

Re: Kelly Formula I am not at all familiar with Kelly's paper or his formula algorithms, so I am dependent on you and any other source I can find to try to understand Kelly's formula s.
Is it possible that the "multiple horses" section of the Wikipedia article describes what you are trying to do? This described algorithm requires a few iterations, but the basic equations along that iteration seem simple enough that one should be able to program those equations into Excel and figure out the iterations needed.
Re: Kelly Formula I think this can be done in solver, though I don't have any real experience with Solver or the Kelly formula. He has written an interesting book The House Advantage , which examines what he learned about managing risk from playing blackjack.
He also covers some of the measures put in place by casinos to prevent the team winning! See also: suggested books on probability and statistics and suggested books on investment and automated trading.
The Kelly Strategy Bet Calculator is intended for interest only. We don't recommend that you gamble. We don't recommend that you place any bets based upon the results displayed here.
We don't guarantee the results. Once we've estimated the probability of winning and losing and the payoff, all we have to do now is some simple arithmetic to estimate how much of our portfolio we should invest in a company.
So to run through a simple scenario: Suppose I offer you a coin flip that pays even money. How much of your money should you bet on this?
The probability of winning is. Suppose instead that I offered you a coin flip, except this time I offered you 2-to-1 odds. The probability of losing is 0, and since you can't lose, you might as well put all your money in.
Although any formula is only as good as the estimates and data plugged into it, this formula forces investors to think in terms of payoffs and probabilities when investing in a company.
It also prevents investors from investing in low-payoff, high-risk companies -- which is the definition of most "hot" stocks, where the easy money has already been made and the risk that the stock will tank is high -- and instead guides investors toward low-priced stocks where most of the risk has been taken out and potential payoffs are high.

The Motley Fool has a disclosure policy. 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.
