Shares of BSE Ltd tumbled sharply on Thursday, falling as much as 5.6% intraday, just a day ahead of the record date for the 2:1 bonus share issue. The decline comes amid market concerns over a possible expiry day shift by NSE, which could dent BSE’s recent gains in the derivatives market.

As of 3 PM, the BSE shares was trading at Rs.6,983, down Rs. 322 or 4.41%, after opening flat. Despite today’s fall, BSE shares are still up 12% in May and have rallied 48% over the last six months. Over the past year, BSE stock has delivered a massive multi bagger 168% return for its investors.

NSE’s New Expiry Day Plan Could Hurt BSE’s Business

The stock market regulator SEBI may soon issue new rules to fix the day when weekly trading contracts called derivatives expire on different stock exchanges, as per a CNBC report.

Right now, BSE’s derivatives expire on Tuesday, and NSE’s contracts end on Thursday. But now, NSE wants to shift its expiry day to Tuesday too, the same day BSE uses.

If SEBI allows this, it could be bad news for BSE. Since NSE is a much bigger player, most traders may choose NSE over BSE, which would reduce trading activity on the BSE platform. That’s a setback for BSE, especially as it has been trying hard to grow its business in the derivatives segment.

BSE Bonus Issue 2025: Record Date on May 23

Investors were eagerly awaiting the 2:1 bonus share issue by BSE, which was approved in March 2025. In a recent stock exchange filing, BSE confirmed Friday, May 23, 2025, as the record date to determine the eligibility of shareholders for receiving two bonus shares for every one share held.

This is BSE’s second bonus issue after its previous bonus declaration in March 2022. While the bonus announcement was seen as a positive trigger, the near-term pressure from NSE’s expiry day change has weighed on sentiment.

BSE Q4 FY25 Results Highlights

The strong results were expected to drive bullish sentiment; however, the external headwinds have temporarily capped further upside.
