Regulatory authorities have found preliminary evidence that the closing prices of major Indian stock market indices were manipulated. The Securities and Exchange Board of India (SEBI) has alleged that entities named Copthall Mauritius and Mansi engaged in activities designed to artificially inflate the Sensex's final trading price. This investigation suggests that specific trades were executed to influence the benchmark index's closing level.
