The Bigger Number Is The Smaller Return | 2026-07-05 morning

A friend sent me two fund screenshots on Saturday and asked which one to buy.

One was up 214 percent. The other, 19 percent a year. He had already half decided on the loud one, and I understood why. Two hundred and fourteen is a big, satisfying number. Nineteen looks almost apologetic next to it.

So I asked the only thing the screenshots were quiet about. Over how long?

The 214 percent fund had been running for twelve years. Spread across those years, that is about 10 percent a year. The other fund's 19 percent was already a per year figure. So the fund with the giant total was earning barely half as much each year as the modest looking one. The bigger number was the smaller return. It had simply picked the flattering way to say itself.

Here is the part worth keeping. A total return and a per year return are two different languages, and most fund posters quote whichever one sounds bigger. An old fund shows you its enormous lifetime total. A young fund on a hot streak shows you its punchy annual figure. Neither is lying. They are just counting on you not to convert.

You cannot compare two funds until both numbers are annualised and both cover the same stretch of time. And even then the span cuts the other way too. Nineteen percent over three years is a small sample. Ten percent over twelve is a longer record. Same basis, same length, then you judge.

A return has two halves. How much, and how long. Quote one without the other and you can make almost anything look like almost anything.
