BSE’s trading activity eased after last week’s sharp rebound, though volumes remained well above the lows seen earlier this month, according to Nuvama Institutional Equities.

BSE’s average daily premium turnover value (ADPTV) stood at Rs 21,300 crore, down 6.6% week-on-week, compared with a 4.6% decline for the industry. The figure was above Nuvama’s remaining FY27 ADPTV estimate of Rs 18,600 crore.

Average daily contracts traded on BSE fell 8.5% week-on-week to 105 million, in line with the industry’s decline. The exchange recorded 98 million contracts in August 2026 and 150 million in July 2026.

Premium per contract rose 2.1% week-on-week to Rs 2,028, compared with Rs 1,897 in August and Rs 1,688 in July.

BSE’s ADPTV market share stood at 34.3%, down 70.8 basis points week-on-week.

For FY27 to date, BSE’s ADPTV is around Rs 26,200 crore, while its ADPTV market share is around 35.2%. Its premium-to-notional turnover ratio is around 12.4 basis points, compared with 17.2 basis points for the industry.

Separately, the Closing Auction Session (CAS) remains under discussion, with Sebi chairman Tuhin Kanta Pandey saying the mechanism is “here to stay” while acknowledging that liquidity could remain a concern during the initial stages of implementation.
