Stock Markets This Week: The Diwali festival arrived early on Dalal Street as Indian equities extended their winning streak to seven consecutive sessions, supported by US midterm election results, strong foreign institutional investor (FII) inflows, easing crude oil prices and robust Q2FY27 corporate earnings.
The rally helped the BSE Sensex and NSE Nifty50 clock one of their sharpest weekly gains in recent years. A global sell-off in AI-linked stocks and softening US bond yields further lifted investor sentiment ahead of Diwali 2026.
The Nifty50 surged 8.58% during the week, gaining nearly 1,978 points to reclaim the 25,000 mark. This was its biggest weekly percentage gain in about six years, since January 2021, and its largest-ever weekly advance in absolute terms. The Sensex rallied nearly 9% to close above 81,000.
The rally added nearly ₹28 lakh crore to investors' wealth, with the combined market capitalisation of BSE-listed companies rising from ₹475.34 lakh crore to around ₹503 lakh crore.
Among the top gainers, Shriram Finance led with a nearly 17% rise, followed by Bajaj Finance and M&M, which gained over 15% each. HDFC Bank jumped around 14%, while Reliance Industries (RIL) added over 13%.
