Last year’s #1 fund is next year’s lesson in humility.
The most natural instinct in investing (move money to whatever just won) is also one of the most reliably expensive. Eighteen years of large-cap fund rankings make the case better than any lecture.
Line up the top-10 large-cap funds for every calendar year from 2008 to 2025 and the table looks like a game of musical chairs. The fund that crowned one year (including one that rose over 100% in 2009) drifts to the middle of the pack in the years that follow. Different market phases reward different styles, and no style stays in season.
Now look at the same funds over the whole eighteen years: their long-run returns cluster inside a band of roughly five percentage points. The dramatic yearly differences mostly wash out. What didn’t wash out was the behaviour of the investor, because switching means exiting a style after its bad phase and entering another after its good one, paying exit loads and taxes for the privilege of buying high twice.
The dull conclusion is the profitable one: pick a sound, diversified fund with a process you understand, and give it the one input that actually separates outcomes, uninterrupted years. Review annually for genuine deterioration, not for last year’s rank.
What does simply staying put build? Run a 20-year SIP: then add a yearly step-up and see what patience plus increments does.
