Shares of BSE Ltd., Asia’s oldest stock exchange, plunged over 9% in early trade on March 5 after its competitor, the National Stock Exchange (NSE), announced a significant change in Futures & Options (F&O) expiry dates.

Key Change: Nifty F&O Expiry Moves to Monday 📅

Starting April 4, all Nifty index weekly futures and options (F&O) contracts will expire on Mondays instead of Thursdays. Additionally, monthly F&O contracts will now expire on the last Monday of the expiry month, the exchange confirmed.

Why the Change?

According to an NSE spokesperson, the decision was made not for financial gain, but to align with market efficiency and global geopolitical developments, which often unfold over weekends.

“Monday is a great day to have expiry, considering the global events that unfold over the weekend. We have received feedback, but we are prioritizing efficiency. We will review the change if necessary,” the spokesperson stated.

Impact on Trading Activity & Market Share 🏦

Market experts believe this shift could increase trading activity on Fridays, as traders may prefer to square off positions before the weekend rather than carry forward risk. Analysts also see this as part of NSE’s strategy to regain market share in the options segment.

With BSE stock reacting sharply to the news, investors are closely watching how this change will impact trading volumes and market dynamics in the coming weeks. 📊🔥
