Investing Lessons From Darwin

Evolution, boiled down to three investing mantras: avoid big risk, buy high quality at a fair price, and be very lazy.

Evolution has already solved the investor’s problem: how to survive, and thrive, in a world nobody can predict.

The whole lesson fits in three mantras.

1Avoid big risk
2Buy high quality at a fair price
3Don’t be lazy, be very lazy

1. Avoid big risk

In nature there are two kinds of mistake. Running from a rustle that turns out to be the wind costs a little energy. Ignoring a rustle that turns out to be a lion costs your life. Animals that survive are wired to avoid the second kind, even if it means making the first kind often.

Investing works the same way. Missing a winner is cheap. Owning a disaster is not. So steer clear of the obvious killers: heavy debt, untrustworthy management, and industries that change too fast to predict.

2. Buy high quality at a fair price

Nature doesn’t care about promises, only about what survives. Apply the same test to businesses: not the story, but the record. A company that has earned high returns on capital for many years, through good times and bad, has already proven it is fit.

Then pay a fair price. Not a bargain for a weak business, and not any price for a great one.

3. Don’t be lazy, be very lazy

Most of the time, evolution is remarkably still. Species stay largely the same for very long stretches. Great businesses do too: their essentials change slowly.

So once you own one, do almost nothing. Ignore the daily news, the forecasts and the price swings. Patience, not cleverness, is what does the work.


DARWINThree questions before I buy
  • Could this investment seriously hurt me if I am wrong?
  • Has this business proven its quality over many years, not just promised it?
  • Am I happy to hold it and do nothing for a decade?

Survive first. Own the fittest. Then let time do the rest.
