For a long time, the US stock market has been driven by the boom in artificial intelligence (AI) and technology stocks. Who will benefit from the big round when the "seven tech giants" no longer dominate the US stock market. To put it simply, the surge in the US stock market is largely attributed to the "Big Seven" technology giants, and the issue of excessive concentration has also sparked controversy and concerns. The weight of the "Big Seven" in the S&P 500 index is so significant that strategists from investment bank Piper Sandler wrote in a report released on June 3 that they will no longer set a target price for the S&P 500 index because the enormous influence of these seven stocks means that the S&P 500 index can no longer represent the US stock market. However, now it seems that the era of the "seven tech giants" dominating the US stock market is slowly coming to an end, and the big round is finally about to begin. The most impressive performance in the US stock market on Tuesday was not only the S&P 500 and Dow Jones Industrial Average reaching new highs, but also the "small cap rebound" - the Russell 2000 index surged 3.5%.
