Mumbai: The stock market's advance-to-decline ratio has fallen to a seven-month low in October, exposing the weakness beneath gains in benchmark indices.While the Sensex and Nifty have risen 2.3% and 1.4% respectively, the BSE MidCap 150 and BSE SmallCap 250 indices have declined 3% and 4.2% respectively, through this month. This reverses the broader trend in favour of small- and mid-caps seen thus far this year, underscoring the recent divergence between frontline stocks and the broader market.The average advance-to-decline (A/D) ratio fell to 0.9 in October so far, its lowest level since March 2026, when the Iran-US war triggered a selloff in global equities. The ratio fell below 1 for the second consecutive month, indicating that declining stocks outnumbered advancing ones and signalling continued weakness in market breadth.135337101Ravi Singh, chief research officer at Master Capital Services, attributed a significant part of the recent weakness to the Jio Platforms IPO, which diverted liquidity from the secondary market as investors set aside funds for the issue.Profit-booking after the strong rally in midcap and smallcap stocks, stretched valuations and uneven corporate earnings have also weighed on sentiment, market experts said. Investors are becoming less willing to pay high prices based on future growth expectations when earnings and cash flows do not justify valuations. Institutional money is also rotating towards larger, more liquid companies with stronger balance sheets and predictable earnings, helping benchmark indices remain relatively resilient.Read more: Market Trading Guide: Eternal among 2 stocks to buy for Friday for healthy returnsRising energy costs pose an additional concern for India, given its dependence on imports, with implications for inflation and corporate margins.
