Market wrap: Top gainers and losers on Nifty and Sensex today

The Sensex surged over 964 points to close at 78,151, while the Nifty 50 gained around 262 points to end at 24,334, driven by large-cap strength in IT and banking sectors. Broader markets lagged, with the Nifty Midcap 100 and Smallcap 100 indices declining up to 0.4 percent, as domestic institutional investors rotated from expensive mid- and small-caps into attractively valued large caps. Technical analysts noted a breakout from a five-day consolidation, with the index likely to advance towards 24,800 and immediate support placed at 24,200.
