Robinhood has been added to the S&P 500 index as of September 5, 2025, while MicroStrategy was not included despite its strong performance. MicroStrategy CEO Michael Saylor noted the company's impressive 92% annualized gain, which outpaced both the S&P 500 and Bitcoin. However, MicroStrategy's focus on Bitcoin and associated volatility were seen as potential drawbacks compared to Robinhood's stable fintech operations. Following the announcement, MicroStrategy's stock fell nearly 3% in after-hours trading, while Robinhood's shares surged by 7%. Analysts remain optimistic about MicroStrategy's future, with some raising their price targets. This development highlights the cautious stance towards crypto-centric companies in major index inclusions.
