Indian equities staged a dramatic late-session recovery on Monday, May 18, 2026, to end marginally in positive territory. The NIFTY 50 closed at 23,649.95, up 6.45 points or 0.02%, after recovering from earlier losses.

Strong buying in information technology stocks helped lift the index in the final hours of trade, while pharmaceutical shares also supported the rebound. However, persistent selling in financials, automobile and metal stocks kept overall gains subdued.

NIFTY 50 Performance Overview

The benchmark index opened on a weaker note and traded under pressure for most of the session. Selling by overseas investors continued to weigh on domestic equities, contributing to volatility in the market.

The Indian rupee also remained under strain as foreign outflows persisted amid concerns about global economic growth. A sharp late-hour rally led by IT stocks helped the index recover losses and close marginally higher.
