This document summarizes and compares the Harshad Mehta scam from 1992 and the Ketan Parekh scam from 2001 in India. Both scams involved improperly using the banking system and stock markets to artificially inflate stock prices. The Harshad Mehta scam had a larger impact and caused the Sensex to lose Rs. 100,000 crore in market capitalization. In response, the Securities and Exchange Board of India (SEBI) was established to regulate the stock market and prevent future scams. SEBI implemented reforms like imposing margins on trades and banning improper practices, but several other scams still occurred, showing the need for stronger enforcement of regulations.
