Ontic FinserveThe benchmark Sensex experienced significant volatility during the Closing Auction Session on a recent F&O expiry day. This session is the final 15 minutes of trading where market participants can place orders to determine the day's closing price. The intense activity led to sharp intraday swings, reflecting the high volume of index futures and options being squared off by traders to manage their positions.
This volatility is a standard feature of F&O expiry days. As traders close out their contracts, it creates a rush of buying or selling pressure that can cause the index to move rapidly. For investors, this session is crucial as it sets the reference price for settlement and can influence the sentiment for the next trading session.
Moving forward, investors should monitor the volume of trades during the auction session. A sudden spike in volume often indicates the direction the market is likely to take for the remainder of the day. Keeping an eye on these patterns can help in understanding the underlying market momentum during such volatile periods.
