India small- and mid-caps: nearly half trading at losses

That divergence is already visible in fund performance and price action. Mid-cap mutual funds have delivered strong long-term returns, with 12 schemes posting annualized gains above 18% over 10 years, but recent performance has been uneven across three-, five- and 10-year periods. A small-cap stock recently surged to a 52-week high with a 14% intraday jump, showing how concentrated the upside has become even as the broader universe remains under pressure.

The market backdrop is also less supportive than the headline indices suggest. The Nifty Smallcap and mid-cap segments have been far more volatile than large caps, and that fragility shows up in the exchange-traded fund proxies as well: the iShares Russell 2000 ETF, IWM, and the iShares Core S&P Mid-Cap ETF, IJH, have both been choppy, while the S&P 500 has continued to attract capital as a relatively safer large-cap trade. In technical terms, IWM has slipped back below its 50-day moving average and its relative strength index has dropped into weaker territory, a sign that smaller US stocks are also struggling to sustain momentum, even as the broader market remains near elevated levels.

For investors, the implication is straightforward: beta is no longer enough. The recent outperformance of a handful of large names, including TCS in India, reinforces the idea that capital is concentrating in firms with scale, predictable earnings and defensiveness. That leaves higher-risk pockets of the market exposed to any disappointment in growth, margins or funding costs.

There is also a diversification lesson. A separate study found that large- and mid-cap funds and multi-cap funds from the same asset manager can overlap by as much as 79.4%, meaning many investors may be paying for diversification they are not actually getting. In an environment where nearly half of small- and mid-cap names are in loss-making territory, that overlap can leave portfolios more concentrated than they appear.

The near-term test will be whether earnings catch up with valuations or whether the market continues to punish anything without clear profitability. If rates stay restrictive and risk appetite stays selective, the winners are likely to remain the few stocks with visible growth and strong cash flow, while the rest of the small- and mid-cap universe may keep lagging.
