On May 15, 2026, the Indian stock market experienced positive momentum, with the Sensex gaining over 450 points and the Nifty 50 surpassing 23,800. This rise was attributed to strong quarterly results from several companies, leading to significant price movements. Vodafone Idea emerged as a standout performer, with more than 66 crore shares traded, pushing its stock price up by 3% to a 52-week high of ₹13.33. This marked a 28% increase in May, following a 20% rally in April. The company's board is set to meet on May 16 to discuss potential fundraising options. Bharat Coking Coal also showed strong performance, with a 13% increase and over 13 crore shares traded, marking its fourth consecutive day of gains. Meanwhile, Adani Power faced a 5% decline despite trading more than 4 crore shares, attributed to recent news of receiving approval for an acquisition. Nazara Technologies reported a notable rise in profits, contributing to an 18% stock increase. The market's mixed signals reflect ongoing sectoral shifts, particularly a decline in IT stocks contrasted with strength in pharmaceuticals.
