MCX shares experienced a significant apparent drop of over 80% on Friday, falling to an intraday low of Rs 2,192 from Thursday's close of Rs 10,988.60. This sharp decline is a technical adjustment due to MCX's 5:1 stock split, with Friday being the record date. Each existing share was divided into five, adjusting the price per share accordingly without altering the total investment value. The split aims to improve affordability and liquidity, and the stock later traded higher post-adjustment.
