5 Betting Strategies That Also Work in Investments

Betting and investing share many similarities. Both require a keen understanding of probabilities, a strategic approach, and managing risks. Whether placing a bet on a horse race or investing in stocks, you need to make informed decisions to increase your chances of success.

Just as betting carries risks, so does investing. In both cases, there’s always a chance of losing money. This inherent risk means that strategies used in betting can also be applied to investments. The skills needed to evaluate odds, manage resources, and make strategic choices are valuable in both fields. As such, bettors’ approaches to maximise their winnings can also help investors improve their returns.

Here are five betting strategies that can be effectively used in investments. 


Arbitrage is a strategy that leverages price discrepancies between different markets. In betting, arbitrageurs place bets on all possible outcomes of an event on various bookmakers, regardless of the outcome, to guarantee a profit. This is possible because different bookmakers may offer different odds for the same event. 

However, note that some bettors may place bets on local bookmakers due to their area’s restrictions. For example, New Zealanders might only do so on an NZ sports betting site, or people in Montana in the United States can only place sports bets at retail locations in the state “in-person.”

In investments, arbitrage can be used to exploit price discrepancies between different markets or financial instruments. For example, if a stock is priced differently on two exchanges, an investor can buy it on the cheaper exchange and sell it on the more expensive one, pocketing the difference. This strategy requires quick execution and a keen eye for market inefficiencies.

The Martingale Strategy

The Martingale strategy is well-known in betting circles, especially in games like roulette. The idea is simple: each time you lose a bet, you double your stake for the subsequent round. By doing this, when you eventually win, you recoup all your previous losses and earn a profit equivalent to your initial stake.

This strategy can be used to manage positions in volatile markets in investments. For example, if you’re investing in stocks and the price drops, you might buy more shares at the lower price, anticipating that the value will eventually rebound. This approach can help average down the cost of your investment, positioning you for a better return when the market recovers.

The Kelly Criterion

The Kelly Criterion is a formula used to determine the optimal size of a series of bets. In betting, it helps you determine how much of your bankroll to wager on a given bet to maximise your long-term growth. The formula takes into account the probability of winning and the potential payout.

To calculate the Kelly Criterion, start by determining the odds offered on the bet and estimating the probability of winning. Next, calculate the probability of losing, which is simply 1 minus the probability of winning. Then, apply the Kelly Criterion formula: (odds times the probability of winning minus the probability of losing) divided by odds. 

The Kelly Criterion can allocate resources among different assets in investments. Calculating the optimal investment amount in each opportunity enables you to maximise your portfolio’s growth while managing risk. This method is beneficial for investors who want to ensure they’re not overcommitting to any single asset.

For example, if the expected return is 3 to 1 and the probability of a positive outcome is 40%, the calculation would be (3 x 0.4 – 0.6) / 3. Solving this, you get 0.2, meaning you should invest 20% of your capital. This method helps determine the optimal fraction of your capital to invest to maximise long-term growth while managing risk.

Value Betting

Value betting is a strategy where bettors look for odds they believe are undervalued by bookmakers. Identifying bets where the potential payout is higher than the perceived risk enables value bettors to profit over the long term. This requires a deep understanding of the sports or events being bet on and the ability to spot favourable odds.

Value betting follows a similar principle in investments, where it is known as “value investing.”  Investors look for stocks or assets that they believe are undervalued by the market. Purchasing these undervalued assets benefits them when the market eventually recognises their true value, and the prices rise. This strategy requires thorough research and a keen eye for identifying mispriced opportunities.


Hedging is a common strategy in both betting and investing. In betting, hedging involves placing bets on multiple outcomes to minimise the risk of losing. For instance, a bettor might place a primary bet on one team but also place smaller bets on other possible outcomes to cover potential losses.

In investments, hedging works similarly. Investors might use financial instruments like options or futures contracts to protect against potential portfolio losses. For example, if you own a stock that you believe might drop in value, you could buy a put option that increases in value as the stock price decreases, thereby offsetting your potential losses.

Final Thoughts

Many betting strategies can be successfully applied to investments. However, investment landscapes constantly change, so these approaches may not always be as effective as before.
