As for how long the trend of the Mag seven and other tech newcomers leading the market can last, this may depend on various factors, including earnings realization, market sentiment, and more. Taking Nvidia, which rose more than 200% last year, as an example, although its valuation appears to be high, repeatedly exceeding earnings expectations has repeatedly proven the reasonableness of its valuation. The market currently generally believes that except for Tesla, the six companies among the tech 'seven giants' will continue to drive the earnings growth of the S&P 500. This week, U.S. tech stocks such as Tesla and Intel will release their financial reports one after another, and whether they can deliver convincing performance will largely determine how far this round of market trends can go. In addition, from last year's situation, FOMO (fear of missing out) sentiment may also be an important reason for the upward momentum of U.S. stocks.
