For bettors seeking an edge, mathematical strategies trump gut feelings every time. A prime example of such an approach is the Kelly Criterion, which helps bettors determine the ideal stake amount. Keep reading to learn more.
Before laying down a wager, bettors should ponder six critical questions: who, what, when, where, why, and how? For the purposes of this discussion, we're focusing on 'how' – specifically, how much to bet, utilizing the Kelly Criterion.
Imagine you're betting on the English Premier League. Here's how these questions might break down:
Who to bet on? Manchester United
What to bet on? Top 4 finish
When to bet on? Now
Where to bet on? 7x7Bets tend to offer the best odds
Why to bet on? They seem to be under-priced
How much? How much to bet on this outcome?
While most discussions center on the first five queries, employing statistical and mathematical logic to justify the 'why' – as seen in discussions on using Monte Carlo simulations – the question of 'how much to bet' remains paramount.
In finance, choosing where to invest isn't the only challenge; deciding how to allocate one's resources across various investments is equally critical. Likewise, a gambler's key decision is not just what to bet on, but how much to bet.
The Kelly Criterion, or variations thereof, comes highly recommended by numerous studies, including a 2013 article in The Journal of Gambling Business and Economics. This formula suggests betting a fraction of your bankroll on a bet with odds better than expected, thereby promoting exponential growth of your funds.
The Kelly Criterion formula is:
(BP - Q) / B
B = the Decimal odds -1
P = the probability of success
Q = the probability of failure (i.e. 1-p)
Using a coin as an example of Kelly Criterion staking
Consider a bet on a coin landing heads at odds of 2.00. If the coin is biased with a 52% chance of landing heads, the calculation is as follows:
In this case:
P= 0.52
Q = 1-0.52 = 0.48
B = 2-1 = 1.
This works out at: (0.52x1 – 0.48) / 1 = 0.04
Hence, the Kelly Criterion advises a 4% stake. A positive value indicates an advantage for your bankroll, facilitating exponential growth.
In comparison to other staking strategies like the Fibonacci or Arbitrage methods, the Kelly Criterion presents a lower risk profile. Nevertheless, it demands accurate estimation of an event's likelihood and strict adherence to avoid the quick depletion of your bankroll.
