The Indian stock markets have shown a strong performance, with indices gaining for the fifth consecutive day as of December 5, 2024. Foreign Institutional Investors (FIIs) have played a significant role in driving this rally, with net purchases of ₹1,797.60 crore on December 4 and ₹8,539.91 crore on December 5. This follows substantial FII inflows of over ₹13,000 crore on December 2 and 3, reversing the trend of significant outflows in October and November. Domestic Institutional Investors (DIIs), on the other hand, have been net sellers, offloading ₹900.62 crore on December 4 and ₹2,303.64 crore on December 5. Meanwhile, the Securities and Exchange Board of India (SEBI) has proposed several regulatory changes, including the conversion of in-the-money (ITM) single-stock options into futures contracts one day before expiry, the introduction of a 15-minute Close Auction Session (CAS) from 3:30 PM to 3:45 PM in the equity cash market, and a new mechanism for determining stock closing prices. SEBI has also cautioned investors against unregulated bond platforms selling unlisted securities. These measures aim to enhance market stability and improve settlement processes. Retail investors have also shown aggressive buying behavior, contributing to the market's momentum.
