BSE shares zoom 11% in two days amid heavy volumes; hit fresh high at Rs 2,670

Amid high trading volumes, the BSE stock rallied 11% in 2 trading sessions, hitting its new all-time high of Rs 2,670 on the NSE today. On Friday alone, the stock witnessed a rally of 8.3%.

Around 1 pm today, 119.72 lakh shares of the company were traded on the NSE, with a total traded value of Rs 3,120.80 crore. BSE’s total market capitalisation at the time stood at Rs 1.07 lakh crore.

The surge in the stock also follows a recent circular released by the markets regulator, Securities and Exchange Board of India (Sebi), which asked the exchanges to choose expiry days for equity derivatives - either Tuesday or Thursday.


After reviewing inputs from a discussion paper released in March 2025, Sebi’s Secondary Market Advisory Committee (SMAC) held deliberations and proposed restricting expiry days to help curb excessive market activity.

Stock exchanges will now need to standardise the final settlement day for equity derivatives contracts—including index options, index futures, and single stock futures and options—by choosing either Tuesday or Thursday as the designated expiry day.

This precedes NSE’s decision to shift the F&O expiry day for Nifty, Bank Nifty, FinNifty, Nifty Next50, and Nifty Midcap Select from the current Thursday to Monday.

With NSE’s derivatives contract expiry, which would have been scheduled ahead of BSE’s Tuesday expiry for Sensex and Bankex, was expected to weigh on BSE’s market share, which could have declined as competition intensifies, according to a previous report by Nuvama Institutional Equities.

This is due to the fact that retail traders tend to be more active closer to expiry when option values compress.
