Volatility triggered by CAS surges on NSE on expiry day
Times of India 1 hr ago·7 Oct 2026, 12:36 am
The Closing Auction Session on the National Stock Exchange (NSE) experienced significant volatility as weekly derivatives contracts expired. The Nifty 50 index surged by over 300 points during the session but subsequently dropped sharply, mirroring similar fluctuations in the BSE Sensex. This rapid movement highlights the intense trading activity that characterizes expiry days, where positions are squared off, often leading to sharp price swings in the final minutes of trading.
Investors should view this volatility as a standard market mechanism rather than a cause for alarm. The price swings were largely driven by falling Brent crude oil prices and positive global cues, which boosted sentiment. However, the market remains cautious as investors await the Reserve Bank of India's upcoming policy decision, which could influence interest rates and inflation outlooks.
Looking ahead, market participants will closely watch the RBI's stance on inflation and potential tightening measures. This event is a key trigger for the broader market. Investors should focus on long-term trends and sector performance rather than reacting to short-term fluctuations, especially during high-volatility periods like expiry days.
