"Market Milestone: S&P 500 Surpasses 5,000, Microsoft Overtakes Apple"

Microsoft surpassed Apple as the world's largest company with a market cap over $3 trillion, fueled by record revenues from cloud computing and artificial intelligence. Communication, technology, and consumer discretionary stocks are the top-performing S&P sectors, outperforming the broader index.
