BSE launches closing auction session, market stays stable on day one
The session opened at 3.15 pm, with order entry beginning at 3.20 pm. The auction closed randomly between 3.28 and 3.30 pm, and the final closing reference price was published at 3.32 pm. A post-closing session then ran from 3.50 pm to 4.00 pm
The Bombay Stock Exchange (BSE) successfully launched its Closing Auction Session (CAS) on Monday, August 3, a significant shift in how the exchange establishes end-of-day stock prices. Over 400 Trading Members took part in the process, covering more than 200 scrips, all without any disruption. The session followed a strict schedule, opening at 3.15 pm with order entry commencing at 3.20 pm.
The auction concluded between 3.28 and 3.30 pm, with the final closing reference price published at 3.32 pm. A subsequent post-closing session took place from 3.50 pm to 4.00 pm. The derivatives segment closed at 3.40 pm as planned.
The SENSEX, which closed slightly lower, recorded a 0.048 percent drop from the 3.15 pm reference price, indicating the new system functioned as expected. Crucial elements such as Limit Price and Market Price order processing, and matching based on the Equilibrium Price methodology, all functioned without any problems. The CAS adhered to SEBI circular guidelines and Exchange standard operating procedures.
The mechanism aims to enhance price discovery at market close, replacing a single-point closing price with an auction-based process, thereby minimizing opportunities for last-minute price manipulation. BSE, Asia's oldest stock exchange and the world's largest by number of listed companies, expects participation to increase in subsequent sessions as trading members become more accustomed to the new system.
