The Hidden Cheat Code In Smallcap Returns That Changes Everything
-
If you follow the stock market even casually, you've probably heard this: "Midcap and smallcap stocks are outperforming the big 50 stocks.”
Sounds straightforward, right? But here's the thing: we might be comparing completely different things.
Think of it like this: imagine comparing the performance of a restaurant's "Top 50 Dishes" list against their "New Trending Dishes" list.
If the trending list changes half its menu every year while the top 50 stays mostly the same, you can't really say the trending list is better. You're comparing different dishes, not different cooking.
That's exactly what's happening with Indian stock indices.
Here Are The Numbers:
Over the last two years
- Nifty 50 (big 50 stocks): Only 6 companies changed. That's 12% of the list.
- Midcap 150 (medium companies): 64 companies changed. That's 43% of the list.
- Smallcap 250 (smaller companies): 127 companies changed. That's 51% of the list.
In simpler terms: Half of the smallcap list is completely different from two years ago. But the big 50? Barely any changes.
Why Does The Basket Keep Changing?
Companies grow. A smallcap becomes a midcap. A midcap becomes a largecap. It's natural.
When companies grow:
- Their share price goes up
- More people want to trade them
- They become more important in the market
- So they get promoted to bigger indices
When new companies become important in the market like new-age technology, data centres, optical fibre, defence, electronics manufacturing, renewable energy and specialised financial businesses companies enter these indices.
So What's Really Happening? Let me explain with an example:
Scenario A: You bought a smallcap stock two years ago that was struggling. You held it for two years. Maybe it did well, maybe it didn't.
Scenario B: You bought the Smallcap 250 index two years ago. Half of today's index wasn't even there two years ago. The index kicked out the struggling companies and brought in the winning companies.
So the index looks like it did great. But that's partly because it constantly replaced losers with winners
The Nifty 50 Works Differently,The big 50 stocks have a different approach. They say: "We're only going to make changes slowly and carefully. We're not going to keep swapping out companies just because something new is trending."
Why?Stability. These companies are established. There's a formal process. Maximum 5 changes per year through regular reviews.
The good part: You know what you're holding is solid and stable.
The bad part: It takes longer to include new, exciting businesses. So if you're holding Nifty 50, you might miss out on the next big tech trend for a while.
The Real Picture When business headlines say "Smallcaps have beaten Largecaps," what they're really saying is:
The basket of smallcaps we're tracking today is performing better than the basket of largecaps we're tracking today but the smallcap basket is 50% different from two years ago."
It's a bit like comparing two different car models by changing the parts halfway through the race.
What Should You Actually Take Away?
Smallcap and midcap indices are constantly refreshing themselves. Some of their stellar performance can come from repeatedly adding companies that are already showing strong growth and removing those that are struggling.
Index returns and stock-picking returns can be very different. If you bought a smallcap stock two years ago and held it, your return could be nowhere close to the Smallcap 250's return.
Comparing indices is not always an apples-to-apples comparison. When one index changes half its constituents while another changes only a handful, their returns are being generated by very different baskets of stocks.
The real story isn't just "smallcap stocks are better." The real story is "the smallcap basket is constantly getting refilled with new success stories, while the largecap basket stays the same."
