The Ketan Parekh scam refers to a major financial scandal in India during the late 1990s and early 2000s. Ketan Parekh, a stockbroker, manipulated the stock market by artificially inflating the prices of certain shares, particularly those of companies linked to the K-10 group. His actions led to significant losses for investors and a loss of confidence in the Indian stock market. In 2001, the scam came to light when the Securities and Exchange Board of India (SEBI) intervened, leading to Parekh's arrest. The investigation revealed that he had used illegal practices, including circular trading and insider trading, to create a false market. The fallout from the scam prompted regulatory reforms in the Indian financial system.
