Biggest falls and gains of the Sensex

It was another Black Monday on the Indian stock markets on May 15, as the Sensex -- the benchmark 30-share sensitive index of the Bombay Stock Exchange -- plummeted by a whopping 470 points during intra-day trading.

Heavy selling by institutions and retail investors alike saw the markets plunge from 12,285 points to almost 11,800 points. The Indian markets seemed to mirror the weakness in the other Asian and emerging markets.
