The US stock market has been on a remarkable upward trend since April, fueled by the Magnificent 7 and advancements in artificial intelligence. However, as companies prepare to release their earnings reports next week, this unprecedented rally is facing a critical challenge. The stakes are high as investors expect impressive results, particularly from mega-cap tech companies, whose earnings have been a major driving force behind the market surge. Despite still being strong, forecasts indicate a potential slowdown in big tech earnings. In light of these developments, the stock market is entering a pivotal moment where company performances will be closely scrutinized and could significantly impact the future trajectory of the market.
