Sundararaman Ramamurthy has been an interesting choice for the publicly-listed BSE, which has seen its chief move to bigger rival -- the National Stock Exchange (NSE) -- in July. Having spent nearly two decades at the country's largest bourse, Ramamurthy is among the early architects of NSE and understands all the cogs of the exchange wheel like only a few others in the country. Just like NSE's core team, which includes its founder RH Patil, the 59-year-old Ramamurthy has worked at the Industrial Development Bank of India (IDBI) before moving to NSE in 1995.
