Indian Equities Begin October with Eight-Week Losing Streak
The Nifty and Sensex indices recorded their longest weekly decline in a quarter-century as October began, recalling past market volatility during the month.
Longest Weekly Slump in 25 Years
The Indian stock market commenced October 2026 by registering its longest sequence of weekly losses in a quarter-century. Market data indicates the Nifty and Sensex indices experienced eight consecutive weeks of declines, a trend not observed for 25 years.
This downturn coincides with global investor apprehension surrounding October, a month historically associated with significant market corrections.
Historical October Declines
Past market events fuel investor caution in October. Historical records show Black Monday, on 19 October 1987, saw the Dow Jones Industrial Average plummet nearly 22% in a single trading day. This represented the largest one-day percentage drop in US stock market history, wiping out an estimated $500 billion in market capitalisation.
Earlier, the Wall Street crash of 1929 included a nearly 13% fall on 28 October, followed by another 12% decline the next day.
Nifty and Sensex in Recent Octobers
Analysis of Nifty and Sensex performance over the past decade reveals varied outcomes during October. The Nifty 50 concluded October 2025 with a 4.51% gain, contrasting with a 6.2% fall in October 2024. The benchmark index saw a nearly 5.4% surge in October 2022, but a marginal gain in October 2021. Further, the Nifty 50 increased by approximately 3.5% in both October 2020 and October 2019.
The current extended losing streak in Indian equities suggests heightened sensitivity to historical patterns among investors. While past October performance for Nifty and Sensex has been mixed, the initial market reaction this month indicates prevailing caution.
Investors will monitor upcoming economic data and corporate earnings reports for signs of a turnaround or continued volatility, particularly given the quarter-century record decline.
