BSE Faces Setback as Expiry Shifts to Thursday; NSE Secures Tuesday Slot

There is a lot of negative news for the Bombay Stock Exchange. According to CNBC sources, NSE has been granted the Tuesday expiry. BSE's expiry will now shift from Tuesday to Thursday. This is very negative news for the Bombay Stock Exchange. SEBI had said that both exchanges can keep expiry on only one day, and that day won’t be the same. It had to be either Tuesday or Thursday for any exchange. The final decision was pending, but now it's clear — NSE has received Tuesday for expiry, and BSE has been given Thursday. This decision means the BSE, which was gaining market share from NSE, may now stop growing. In fact, BSE may start losing its market share in index derivatives. Currently, BSE holds 20% market share while NSE has about 80%. So, this expiry shift is very negative news for BSE. According to analysts, this change could lead to a 7–8% decline in BSE's earnings. Let’s see how the Bombay Stock Exchange stock reacts to this news.
