For sports bettors, the Kelly Criterion sports betting strategy is capable of maximizing potential profit, while minimizing both volatility and threat of depletion to your bankroll. The ultimate solution requires incorporation of research’s scenarios analysis, correlation amongst assets, and picking the array of position sizes that maximizes long-term geometric expected return. The first step is to forecast thousands of arrays of returns for each investment based on its probability weighted scenario analysis resulting from your analyst’s research. Next, choose the one set of arrays from the thousands generated which most closely matches the correlation statistics for each asset and the portfolio.

The Kelly fraction assumes an infinitely long sequence of wagers. According to vast research of chances grown by the Kelly criterion, a punter using it a 1/3 chance of halving his bankroll before actually doubling it. A punter using the “half Kelly” option has a 1/9 chance of halving his bankroll before doubling it.

Because portfolio investing has inherent capital protectors this post by limiting position size maximums, Kelly Criterion breaks down. The formula for Kelly’s Criterion is in principle very simple, it is about your bet being as large as the probability of a win minus the likelihood of a loss. This is to say, if you have a 55% chance of winning and a 45% chance of losing, you should bet 10% of your betting account (55-45+10). As mentioned earlier, the formula discourages you from betting on a game if the value of it is zero or minus. The system reduces the chances of becoming bankrupt because it assumes you always play a certain percentage of your bankroll.

## The Kelly Criterion: Advantages & Disadvantages

A Kelly Criterion Calculator helps you decide what percentage of your bankroll you should wager on a sports bet. So you first need to decide your bankroll size and the length of time you’ll be using the Kelly method. The Kelly Calculator can help a sports bettor decide how much of their bankroll to risk on a wager. The amount recommended is based on the odds offered by the sportsbook as well as an understanding of your predicted winning percentage. By entering your bankroll, the odds and your estimated probability of winning, the Kelly Criterion calculator will tell you how much you should wager on a certain event to maximise your value and profit.

## Advantages Of Betting With The Kelly Criterion

The basis of his blackjack technique – outlined in his famous book,Beat the Dealer– was to determine the extent to which the deck of cards was stacked in his favour and bet accordingly. When you are dealing with reliable and specific numbers – like the fact that there are 52 cards in a deck – then reliably assessing probability is straightforward. There are a lot of people who use data, models and automation to make a living out of professional betting. Here are some of their stories, and some extra tools to help you develop your own strategy. Betfair is one of the only betting platforms in the world that demands winning clients.

If you find a value of 50%, you will then invest 50% of your whole account. If you lost the bet, this would mean that your account would have halved with just one bet. Even if the bet has a mathematical grounding, there are few people who would be willing to bet half their account on one game.

In the first case, the optimal bet is 10% of your wealth, which provides for a potential win of 12.5%. In the second case, you invest 25% of your wealth to possibly get a 50% return (12.5% of your wealth) or lose 40% of your investment (40% of 25% which is 10%). Despite the same effective recommendation, in one case you talk of f being 10%, and in the second 25%. To a person, it matters whether the property emerges over a small number or a large number of bets. It makes sense to consider not just the long run, but where losing a bet might leave you in the short and medium term as well.

The ‘Kelly Criterion’ strategy is deeply related to value betting. It allows you to determine the amount you should value bet to maximize your profit based on all the risks and the probability theory. The original Kelly criterion is proven to be mathematically optimal when placing a single bet, an infinite number of times. In reality, your goal is to maximize your expected bankroll growth over a finite number of bets, often having many simultaneous bets open. The Kelly criterion is a staking strategy that calculates the optimal stake for maximum growth of your bankroll, based on the perceived value of the bet.

## Can Everyone Benefit From Kelly Staking?

Specifically, you’ll need to know the approximate probability of a certain outcome in a football match. You can never be 100% sure about such things in sports, though. That’s why even the Kelly betting strategy is not foolproof. You can probably already intuit that this strategy involves making the minimum bet.

With 100% odds, Kelly eventually wins over any other strategy. I found that there was no strategy that achieved $6.87 with probability 1/2 or greater, so the median is less than $6.87. Okay so I ran my program and I didn’t manage to find the exact optimal median but I narrowed it down a lot. I think I can run a computer search to find the actual optimal strategy. Many applications to high-frequency trading due to the probabilistic nature of outcomes. But the rest of the post analyses a mathematical game which has nothing to do with buying stocks, and is in fact only useful in theoretical situations where you know the precise distribution of outcomes.
