Top 10 winners and losers of Nifty 500 index during the US-Iran war: HFCL, Ola Electric surge while Vedanta, RVNL sinks

Indian equity markets have lost around 4-5% since the outbreak of the US-Iran conflict that began on February 28, with escalating geopolitical tensions and volatile crude oil prices weighing on investor sentiment. On Friday, the BSE Sensex fell 607 points (0.78%) to close at 76,802.90 while the Nifty 50 declined 154.90 points (0.64%) to 24,013.10, snapping a five-session winning streak amid delayed US-Iran peace talks and weak global tech cues after Accenture lowered its revenue guidance. Between February 27 and June 18, 2026, top Nifty 500 gainers included HFCL (191%), Aditya Infotech (108%) and Ola Electric (67.6%), while Vedanta (-57.4%), IDBI Bank (-27%) and Ashok Leyland (-24.9%) were the biggest losers.
