Gland Pharma, GE Shipping, SCI Lead Top Gainers While Amber Enterprises, KEC International and Gallantt Ispat Drag Markets Lower

Benchmark stock indices in India fell on May 18 owing to growing geopolitical risks in the Middle East. The Nifty 50 lost 64.70 points or 0.27% to close at 23,578.80, while the BSE Sensex fell 163.93 points or 0.22% to close at 75,074.06 at around 12:32 PM.
