Every SIP investor has thought about it at least once.
"Last year, small-caps went crazy. Should I move my SIP there?"
It feels smart.
It feels strategic.
But a fresh WhiteOak Capital study just put that instinct on trial.
And the verdict? Painful for the switchers. 👇
Two investors. Same SIP. Same starting point — FY2006, in a Nifty Midcap 150 index fund.
🏃 Investor A plays chess every April — switching to whichever cap (large, mid, small) won the previous year.
🧘 Investor B does nothing. Stays put in mid-caps. Watches Netflix.
Fast forward to 31 May 2026.
🧘 Stay-invested mid-cap SIP: 17.05% XIRR
🏃 Chase-the-winner SIP: 14.76% XIRR
That's a 2.29% annual gap — which, on a 20-year SIP, isn't a rounding error.
It's a vacation home. 🏖️
The 10-year rolling returns tell the same story:
Staying put: 17.55%
Switching annually: 15.75%
Discipline 1, FOMO 0.
Here's where it gets spicy.
When the same experiment started in a Nifty Smallcap 250 fund, switching just barely won:
Switching: 14.75% XIRR
Staying: 14.63% XIRR
A margin so thin you could miss it in the tax filing. 😅
Basically — switching didn't really pay off here either. It just didn't hurt.
Market leadership rotates. Constantly.
Last year's hero is often next year's hangover.
👉 By the time you spot the rally, you're buying the top of it.
👉 Every switch resets the compounding clock — and compounding hates being interrupted.
👉 You pay exit loads, taxes, and the mental tax of overthinking everything.
For context — the Nifty Midcap 150 TRI itself has delivered roughly 22% annualised over the last 3 years. The boring index quietly did the heavy lifting. 💪
The sexiest move in investing… is usually the most boring one.
Pick your category.
Stay.
Let time and compounding do the dirty work.
Because the investor who tries to outsmart the market every April…
usually ends up underperforming the one who simply forgot the password to their app.
That's all for now!
