Tech Megacaps Drive S&P 500 to All-Time Highs Ahead of Q2 Earnings Season

The S&P 500 has reached new milestones, with tech driving much of the recent gains. Nvidia and Tesla are up over 4% this week, while Alphabet and Amazon follow suit. Mark Malek, investment chief at Siebert Financial, says investors expect great things from the Magnificent Seven – a group of megacap companies that account for half of the S&P 500’s expected earnings growth. These companies are projected to post earnings growth of over 14% in Q2, while the rest of the S&P 500 is expected to grow just 3.4%. If Alphabet delivers on its earnings report as expected, it could continue to lift the market and raise expectations for other names reporting later. However, challenges remain, including ongoing uncertainty around President Trump’s tariffs and stretched valuations in the U.S. equity market. Despite these hurdles, many investors are confident that companies can beat expectations this earnings season, driving the market higher.
