The Nifty 50 registered its biggest single-day gain in nearly five months, rising 1.68 percent and marking a strong start to November. The rally was largely driven by index heavyweight Reliance Industries, which surged 11.6 percent following better-than-expected Q2FY27 earnings. The benchmark index opened and closed decisively above its October swing high and the 50-day EMA, accompanied by strong bullish momentum on November 2.
