In 2022, Twitter was removed from the S&P 500 index following its acquisition by Elon Musk and transition into a private company. As a result, passive funds and ETFs tracking the index were required to exit the stock, leading to institutional sell-offs. While the company’s fundamentals were no longer in public focus, the delisting impacted liquidity and visibility among investors.
