📈 Executive Summary
Indian equity benchmarks closed mildly lower for the second consecutive session on Wednesday, August 12, 2026. Market sentiment remained cautious ahead of domestic and US CPI inflation readings, alongside a sharp sell-off in Tata Group stocks led by TCS (-3.71%) following executive leadership announcements.
The Nifty 50 dropped 35.75 points (-0.15%) to settle at 24,435.95 after recovering from an intraday low of 24,313.35. The BSE Sensex fell 187.90 points (-0.24%) to end at 77,966.35. Despite the headline dip, massive domestic institutional buying (DII Net +₹5,841.66 Cr combined) and a robust rally in Bank Nifty (+439.60 Pts / +0.77%) provided strong market depth. Volatility cooled further as India VIX dropped to 11.69 (-1.43%).
