For most of the year, mid-sized companies held up while the Nifty slumped. Since late September, the pattern has flipped. The Nifty Midcap 100 has fallen about 8% from its record, and Thursday’s rally barely touched it.
For much of 2026, the most reliable way to avoid pain in Indian shares was to look beyond the biggest companies.
As of 10 September, the Nifty 50 had fallen about 10% for the year. The Nifty Midcap 100 was up about 2.6%. The Nifty Smallcap 100 had gained 13%. While foreign investors sold large companies, domestic money kept flowing into mid-sized and smaller firms, many of them posting strong earnings.
That divergence is now unwinding.
The record
The Nifty Midcap 100 hit a record of about 64,450 earlier this year, becoming the first broader index to set a new high. It traded above 62,000 for most of September.
Then the selling began. On 24 September, the day the National Stock Exchange listed, the index fell 2.25% to about 60,990. It fell another 1.63% on 28 September and slid further into October, touching a closing low of 57,882.50 on 8 October after a 2.53% drop in a single session.
There has been a partial recovery. The index closed at 59,409.10 on 14 October and eased about 0.4% on Thursday to roughly 59,200. That still leaves it about 8% below its record. By our calculation, it has also slipped slightly into negative territory for the year.
Thursday was revealing. The Sensex jumped 2.11%, its best day in four months. The Nifty Midcap index fell. The Nifty Smallcap 100 dropped 1.31%. Money moved into large companies such as ICICI Bank, Reliance and IT stocks, and out of the broader market.
Why the shift?
Three forces explain the rotation.
The first is valuation. Midcaps had been expensive. At the end of August, the Nifty Midcap 100 traded at about 31 times earnings. When stocks are priced for strong growth, any worry about the future hits them harder.
The second is the change in macro conditions. The RBI raised interest rates in October, and inflation has climbed sharply. Smaller companies often rely more on borrowing and have less pricing power than large firms. Rising costs and higher rates hurt them more.
The third is where the money is moving. Large-cap shares had fallen so far this year that they began to look cheap by comparison. When investors returned to Indian equities, they went first to the biggest and most liquid names. Some institutions also appear to have taken profits in midcaps after a strong run.
The case for midcaps
The correction has improved valuations. By 9 October, the Nifty Midcap 100 traded at about 27.7 times earnings, roughly 7% below its five-year median of 29.8 and well below 32 a year earlier.
Earnings have also been strong. Over the past five years, profits of Nifty Midcap 100 companies grew about 17% a year, faster than the index itself rose. JP Morgan estimated that, excluding energy companies, midcap profits grew 42% year on year in the June quarter. Foreign investors added to their holdings in more than 40 midcap stocks during that period, even as they sold large caps.
So the picture is not one of collapse. It is one of a crowded trade cooling down. Midcaps were the place to hide earlier in the year. Now some of that money is shifting back to large companies that had fallen further.
What to watch
September-quarter earnings will decide the next move. Many midcap companies report over the next three weeks. If profits keep growing at the pace seen earlier this year, the lower valuations could attract buyers again. If rising costs and higher interest rates start to show up in margins, the correction could deepen.
For now, the message from the market is clear. The safe harbour of early 2026 is no longer quite so safe.
