Brokers brace for impact as Sebi’s closing auction session weighs on F&O volumes

Sebi's new closing auction session for stock futures has caused a sharp drop in trading volume. This rule requires trades to be settled at a single price at the end of the day, replacing the continuous price discovery process. Consequently, the trading activity has fallen by nearly half since it began on 3 August.
This shift is significant for investors because it reduces the liquidity available during the day. With fewer trades happening, the market may become less efficient at finding the best price for shares. It also changes how traders manage their risk, as they can no longer exit positions continuously throughout the session.
Investors should monitor how this new system stabilizes the market in the long run. While it may reduce volatility, it also limits the ability to react quickly to news. Traders will need to adjust their strategies to focus on the opening and closing prices rather than intraday movements.
