Kelly Criterion Football Betting Method

In the end, you ‘can’ use Kelly’s Criterion for horse racing but it is best to use an ultra-cautious method of betting. For example, rather than adhering to the maximum Kelly stake, you could reduce your stakes and elect to bet half or even quarter of the recommended wager. There is merit to the idea of using Kelly’s Criterion to get the most out of value bets.

Daring To Quantify The Markets

No matter what the “wizards” here in the tank say, 99.99%+ of the sports betting public cannot use Kelly, no matter which “form” they advocate as they cannot correctly calculate the Bayesian Priors. And the exact sequence of bets could end up busting him flat betting even when it wins with kelly if the losses are frontloaded, but he never mentions that. Time to check the profits from flat betting against the record of the Kelly criterion, and ta-daa!

Mr. Mowery correctly highlights that his fund’s use of Kelly helps increase portfolio potential returns and reduce behavioral bias. The later aspect of behavioral bias is the benefit I find to be the most important attribute of adopting a process for sizing positions. Basic questions like, “how much can we make, what is the downside risk, and what are the probabilities of each”, must be answered before any asset is placed in the portfolio.

Kellybankroll, Odds, Probability, Fractional?

Statistical inference might be thought of as gambling theory applied to the world around us. The myriad applications for logarithmic information measures tell us precisely how to take the best guess in the face of partial information. In that sense, information theory might be considered a formal expression of the theory of gambling. It is no surprise, therefore, that information theory has applications to games of chance. Neither the original Kelly article ever made a single mention of Bayes, yet Wreck here asserts that the formula can’t be used unless you calculate Bayesian Priors. Not being able to calculate edge accurately is why a lot of people use fractional Kelly as this moderates the effect of miscalculating it and also makes it easier to ignore the effect of simultaneous betting.

Advantages And Disadvantages Of Using The Kelly Criterion

That although they were already favorites, I thought that they were overwhelming favorites. And so my true estimate was that it was 1 to 9, or that the favorite’s going to win 90% of the time. And my lower bound, saying like, “If I use very conservative assumptions,” I was very confident they were going to win at least 83% of the time. So, presumably, the market was underpricing these favorites. And then all of that is divided by the odds that you are getting.

Most casual blackjack players have a smaller bankroll than the MIT team. As such, our betting strategy modifies their bet sizing table in order to reduce variance for small bankrolls. Many successful punters use Kelly, or a fraction of Kelly and its use extends beyond the betting world to investment theory in general. A lot has been discussed surrounding Kelly, but it is accepted in the main part as being the optimum strategy for maximising profit.

This makes your equal to 5 but remember that we need to subtract 1 from the odds vale, making it into 4 including the stake. This would be less a Kelly issue and more an issue of the bankroll variable you’re using. Advantage gamblers generally find the concept of “sessions” meaningless – essentially, one’s entire gambling career is just one long session. My understanding of the argument is that you have to assume you keep playing after you lose, so your stake is dictated by the risk. If it’s a fair die, the probability of rolling your point is one-sixth, and you have no edge. But imagine it’s a loaded die and it rolls 2 one-fifth of the time and something else four-fifths of the time.

On the other hand, if I plan to give money to charity then my utility function is almost linear. Big charites can absorb a lot of money without becoming less effective. So in this case you should be maximally aggressive, betting everything at every opportunity. Personally I feel that my utility function is sublogarithmic. If I’m just spending on myself then beyond a certain point additional money makes me absolutely no happier. Note that the usual justification of progressive taxation also assumes sublogarithmic utility.
