Sashidhar Jagdishan, who takes over as the managing director and chief executive officer of HDFC Bank, has some big shoes to fill. His predecessor, Aditya Puri, who retired on October 26, leaves behind an impressive legacy, of having built the country’s largest private bank. Puri, who took over as MD in September 1994, oversaw the bank’s listing on the Bombay Stock Exchange on May 19, 1995. On his watch, HDFC Bank crossed the market capitalisation of Rs 7 lakh crore. The stock has given a return of more than 30,000 percent—jumping from Rs 3 levels in 1995 to Rs 1,200.
