In the strong growth of the US stock market in recent months, the "Big Seven" have always been regarded by investors as a benchmark for the performance of the US technology industry and the overall market. Since the beginning of this year, most members of the "Big Seven" have achieved strong growth. However, after experiencing a sharp decline last week, some investment banks on Wall Street seem to have gradually shifted their views on their prospects. On Monday Eastern Time, UBS Global Research Strategist downgraded the ratings of the other "Big Six" in the US stock market, except for Tesla, and stated that their profit growth momentum may "collapse" in the coming quarters.
