India's benchmark Nifty 50 was the only major market-cap index on the National Stock Exchange (NSE) to post positive returns in October 2026, gaining 1.91%, even as broader market segments ended sharply lower, according to a report released on Monday, 9 November 2026 by Motilal Oswal Mutual Fund. The divergence between large caps and the wider market was stark, with microcap and smallcap stocks bearing the heaviest losses.

Large Caps Hold, Broader Market Bleeds

The Nifty Next 50 declined 2.92% over the month, while the Nifty Midcap 150 dropped 3.75%. The sell-off deepened further down the market-cap ladder: the Nifty Smallcap 250 fell 5.81% and the Nifty Microcap 250 shed 8.95% — more than four times the benchmark's gain in reverse. The broader Nifty 500 declined 0.80% over the one-month period ended 31 October 2026.

This pattern — where the benchmark holds or advances while mid and smallcaps retreat — is a classic risk-off rotation, reflecting institutional preference for liquidity and defensibility when macro conditions tighten.

IT Sector Leads With 17.69% Surge

Information Technology was the standout sectoral performer, surging 17.69% in October — a gain that single-handedly underpinned the Nifty's positive close. Healthcare also ended in positive territory, up 1.93%, while Bank eked out a marginal gain of 0.10%.

On the losing side, Metal recorded the steepest sectoral decline at 7.65%, followed by Defence at 6.17% and Consumer Durables at 5.74%. Energy, Realty, Auto, and FMCG fell 4.58%, 3.95%, 3.31%, and 2.02%, respectively. Within the Nifty 500, Industrials, Commodities, and Consumer Discretionary were the largest drag contributors, each down approximately 0.54% and 0.42%.

Factor Indices: Low Volatility Holds Up Best

Among factor-based indices, Low Volatility recorded the smallest decline, falling just 0.79% in October — signalling that investors sought stability over growth. The Momentum index declined 2.41%, while Quality fell 2.73%, according to the Motilal Oswal Mutual Fund report.

Macro Headwinds: Inflation Up, Rate Hiked, FIIs Sell

The month's market moves unfolded against a tightening macro backdrop. India's CPI inflation rose to 5.54% from 4.83% the prior month, while the repo rate was hiked to 5.50% from 5.25%. The 10-year government bond yield climbed to 7.40% from 7.16%, compressing equity valuations — particularly for rate-sensitive sectors like Realty and Consumer Durables.

Foreign Institutional Investors (FIIs) remained net sellers, recording outflows of ₹24,475 crore in October — a moderation from the ₹58,443 crore in outflows seen the previous month. Notably, Domestic Institutional Investors (DIIs) also recorded net outflows of ₹28,943 crore, suggesting that domestic buying did not fully absorb the foreign selling pressure.

India vs Emerging Markets

India's performance, while mixed across caps, was relatively resilient compared to other emerging markets, all of which declined in October. South Korea recorded the steepest fall among peers at 15.57%, followed by Brazil at 12.11% and Taiwan at 8.37%. Against that global backdrop, the Nifty's modest positive return stands out, even if it masked significant damage in the broader domestic market.

With inflation elevated, rates rising, and institutional flows still negative, the near-term trajectory for mid and smallcaps will depend heavily on whether October's IT rally broadens — or whether large-cap leadership remains a narrow phenomenon driven by a single sector.
