Indian equity benchmarks witnessed sharp selling pressure on Tuesday, August 18, 2026. The BSE Sensex dropped 773.79 points (-0.99%) to settle at 77,235.46, while the NSE Nifty 50 tumbled 211.10 points (-0.87%) to close at 24,154.90, weighed down by broad-based profit booking across heavyweights.
Sectorally, the weakness was led by Banking, IT, and Auto indices, which witnessed heavy institutional offloading. High-beta financials and tech majors were among the top index laggards. On the flip side, defensives such as Pharma and FMCG managed to limit deeper losses, trading with modest gains in an otherwise weak session.
Macroeconomic headwinds added to investor caution, with muted Asian and European cues setting a negative tone. Persistent Foreign Institutional Investor (FII) outflows and elevated crude oil prices kept market participants on edge, even as Domestic Institutional Investors (DIIs) provided cushioned buying at lower levels. Meanwhile, the Indian Rupee consolidated in a tight range against the US Dollar amid cautious global risk appetite.
