On Thursday, Indian stock markets saw severe selling pressure, fuelled by new SEBI futures and options (F&O) regulations and rising geopolitical concerns. The Nifty 50 index dipped 1.33 per cent, or 344 points, to open at 25,452.85. The BSE Sensex also fell sharply, shedding 1,264.20 points, or 1.50 per cent, to start at 83,002.09, reported ANI. 

According to the news agency report, market analysts cited global factors such as the Federal Reserve's recent interest rate decrease, increased geopolitical tensions, and foreign investors fleeing from Indian markets in favour of other areas such as China as important reasons for the sell-off.
