CAS wild swing: Sensex soars 1,000 points on expiry day but ends only 138 points higher
The Economic Times 6 hrs ago·10 Sept 2026, 10:19 am
The stock market experienced a volatile session on expiry day, with the Sensex swinging wildly before closing with a modest gain. The index surged by over 1,000 points during trading hours but settled only 138 points higher by the end of the day. This significant intraday volatility was driven by heavy buying and selling in index heavyweights as traders squared off their positions ahead of the expiry of monthly derivatives contracts.
This type of market movement is typical on expiry days when traders close out their futures and options positions. The sharp intraday rally suggests strong bullish momentum at the opening, while the final settlement reflects profit booking and profit realization. For investors, such swings highlight the importance of understanding the mechanics of derivative expiry and the risks of short-term trading.
Going forward, market participants should watch for cues from global markets and domestic economic data. The next trading session will likely be influenced by the positioning of traders and any fresh developments in the broader economic landscape. Investors are advised to stay cautious and focus on long-term fundamentals rather than reacting to short-term volatility.
