"Tech Dominance: The Magnificent Seven Stocks and Q4 Earnings Expectations"

Despite hopes for a broadening US stock market rally, big tech companies like Apple, Microsoft, and Nvidia continue to dominate profit growth, with the so-called Magnificent Seven expected to deliver a combined profit growth of about 46% in the fourth quarter. While the S&P 500's leadership has shifted recently, concerns about crowded positioning in tech and the potential for a short-term shock remain. However, the options market is pricing in "virtually no risk" for megacap stocks, and some analysts believe any selloff would be short-lived due to the long-term growth potential of big tech companies.
