Sensex drops 624 pts on weak earnings, trade fears; Wall Street up

Markets were volatile Tuesday due to tight valuations, weak earnings, and tariff threats from Trump. The Sensex dropped 624 points, with the Nifty closing at 24,826, while Q4 earnings showed only 5-6% year-on-year growth. IPO activity and global trade uncertainties added pressure, though Wall Street rebounded after Trump delayed EU tariff hikes.
