HDFC Bank, India’s largest private sector lender, witnessed a notable increase of more than 2.5% in its stock price on Friday, anticipating the announcement of its March quarter earnings. The stock surged by 2.64%, closing at Rs 1,534, and contributed significantly to the gains on the Sensex. Despite this surge, HDFC Bank concluded the week with a 1% loss amidst market volatility. Market observers noted that such a significant surge in a blue-chip stock, especially on the eve of its earnings announcement, is unusual, particularly when the earnings outlook remains uncertain.
