Should I switch out of a good mutual fund if it underperforms for 1–2 years?

Recent underperformance by itself does not tell you whether a fund has become bad.

Even funds that eventually generate strong long-term returns can go through periods — sometimes years — when they look weak compared with the benchmark or another investment style.

The behavioural problem starts when investors compare their underperforming fund with whatever is currently doing well.

Suppose your fund has struggled for 18 months. Meanwhile, another fund, sector or theme has produced excellent returns.

The natural reaction is: “Why am I still holding this? Let me move to the better fund.”

But notice what has happened. You are selling one strategy after its weak period and buying another strategy after its strong period.

If you repeat this cycle often enough, you can own good funds throughout your investing life and still produce poor outcomes.

This does not mean that you should never exit a fund. It means that the decision should not be based only on the fact that another fund has recently performed better.

You need to distinguish between a strategy going through a normal period of underperformance and something genuinely changing in the investment you originally chose.

The larger point is that a long-term return chart looks smooth only in hindsight.

When you actually live through that chart, you experience the uncomfortable periods one day at a time. A one-year decline looks tiny on a 20-year chart, but that same year can feel extremely difficult while you are living through it.

The risk is not merely choosing a bad fund. It is repeatedly abandoning good investments during their difficult periods and moving into whatever has just performed well.

“Even a great long-term fund would have gone through periods of underperformance. Sometimes years of underperformance.”

“Over time, the original fund gradually recovers and compounds. But the investor is no longer there.”
