Cut Losers, Let Winners Run

Warren Buffett once quipped that there are two rules in investing. First, don’t lose money. Second, don’t forget the first rule. There is both truth and untruth to this statement, and it’s helpful to investors to know which is which.

First, the untruth. Losses are an ordinary part of ALL successful investing. Even the most successful proprietary traders have losing days 10-20% of the time. On the other end of the spectrum, successful trend-following strategies may lose 70% of all trades. Yes, that’s right—only 30% winning trades. More about this in a moment.

And let’s also acknowledge that Buffett took 50% drawdowns in the balance of his accounts on three separate occasions throughout his career as an investor. Clearly, there is more to his statement than meets the eye.

Here is the truth. If losses are not minimized and managed as part of smart trading or investing plan, they will become a major problem and create losses over the long term. There are trading strategies where 90% of all trades are winners, yet still lose money over time. Why? Because the sum total value of the losses is greater than the sum total value of the gains. This is how trend-following strategies can succeed with only 30% winning trades—the sum total of the winning trades is so large that it exceeds the sum total of the losing trades.

In the end, only three things matter: how often you win, how much you win when you win, and how much you lose when you lose.

Stillpoint’s trading and investment systems tend to win around half the time, but we make money over time because the winners win 2-4x what the losers lose.

This is essence of another, more significant trading aphorism from David Ricardo—cut your losers short and let your winners run. Do you have have answers to these questions for your investment plan?
