Harshad Mehta was a stockbroker known as the "Big Bull" who triggered a stock market rise in India between 1991-1992 through fraudulent activities. He diverted about Rs. 40 billion from banks by exploiting loopholes in a short-term lending mechanism called "Ready Forward" deals. When the scam was uncovered, the Sensex fell sharply from 4500 to 2500, wiping out Rs. 100,000 crore in market value. Several reforms were implemented in response, including banning Ready Forward deals and setting up a special court to try those involved, including Harshad Mehta.
