The market witnessed a gap-down opening today as US President Trump indicated plans to levy 25% tariffs on Pharmaceutical Imports, which may trigger the business of Indian drug manufacturers. This led to a fall of 2% in the Nifty Pharma index. Aurobindo Pharma tumbled by 9.5% to 1055, Dr Reddy laboratories dropped by 5.8%, and Sun Pharma dropped by 3.2% to 1648 during the market opening.
