最新报道:Robinhood (HOOD) stock surged 15% on Monday after being added to the S&P 500, effective September 22, marking a milestone for the trading platform whose shares have nearly tripled this year. Meanwhile, MicroStrategy (MSTR) fell 1.5% after being excluded from the index despite meeting eligibility with $14 billion in operating income and $10 billion in net income for Q2 2025, driven by bitcoin's rally. CEO Michael Saylor noted he hadn’t expected immediate inclusion, while analysts suggested the committee may be cautious due to the company’s heavy bitcoin exposure.
