BSE shares slip 3% exchange flags lower volumes due to CAS
Economic Times 1 hr ago·2 Sept 2026, 7:35 am
BSE shares fell 3% on Wednesday as the exchange flagged that its new Closing Auction Session (CAS) had led to lower trading volumes. The move, aimed at improving price discovery, has coincided with a significant drop in equity derivatives turnover, which hit multi-month lows in August. Consequently, the exchange's average daily traded value fell 26% month-on-month, reflecting reduced market activity from traders.
This shift in trading patterns is notable for investors as it signals a temporary slowdown in liquidity. While the CAS is designed to enhance market integrity, the immediate impact has been a contraction in daily volumes. Market participants are now closely watching whether this dip in activity is a short-term reaction to the new system or a broader trend that could affect liquidity in the near term.
