On Monday, 2,837 stocks advanced, 1,552 declined and 211 remained unchanged on Bombay Stock Exchange with advance decline ratio of 1.83 indicating a positive closing. Indian stock markets saw a dramatic and unexpected late-session spike, with the Nifty 50 jumping close to 200 points in just the final few minutes of trading. Many traders initially panicked, assuming something had gone wrong with the systems. However, the real reason was the rollout of SEBI's new Closing Auction Session rules, which fundamentally changed how closing prices are determined for F&O stocks. Instead of the old method of averaging prices over 30 minutes, trading now stops at 3:15 PM and a single clearing price is worked out over the next 20 minutes by matching all pending buy and sell orders. On the very first day of this new system, big institutions and index funds rushed in with heavy buy orders on major stocks like HDFC Bank, Reliance, and ICICI Bank, which drove prices sharply upward. This also meant Nifty gained far more than the Sensex, since all its 50 stocks went through the auction process, whereas Sensex's smaller basket was less affected. Another odd but notable outcome was that almost every Nifty stock closed at a perfectly round rupee figure — something never seen before in Indian markets — simply because the new auction mechanism naturally settles at clean price points rather than the messy decimals the old averaging method produced. Brokers are now advising traders to rethink their strategies, especially since stop-loss orders on F&O stocks will automatically get cancelled at 3:15 PM going forward. The trend of the major indices on Monday’s trading is given in the table below.
