1. On November 9th, the Nasdaq Composite rose 2.74%, the S&P 500 rose 2.35%, and the Dow Jones Industrial Average rose 2.15%. The difference between the S&P 500 equal-weighted index and the market capitalization-weighted index widened compared to the previous trading day, nearing the upper limit of its nearly one-year fluctuation range.
2. The Russell 2000 index closed up 3.15%, approaching its highest point since October, outperforming the three major indices.
Overall, this rebound is not limited to large-cap stocks; funds are flowing into small and mid-cap stocks, improving market breadth.
-------- Note: The difference between the S&P 500 equal-weighted index and the market capitalization-weighted index reflects the breadth of gains or losses in the US stock market and the concentration of market performance.
1. A widening difference indicates that more stocks are outperforming large-cap stocks; if the market rises, it means that the upward momentum is spreading to more companies, and the market is likely to see a broad-based rally; if the market falls, it indicates that large-cap stocks are falling more, while other stocks are relatively more resilient.
2. A decreasing difference indicates that market performance is more reliant on large-cap stocks. If the market rises, it means the gains are mainly driven by large-cap stocks such as tech giants; if the market falls, it indicates that more small and mid-cap stocks have experienced significant declines, while large-cap stocks have shown relative resilience.
3. A negative difference means that the equal-weighted index is underperforming the market capitalization-weighted index. However, whether there is a risk of over-concentration needs to be assessed in conjunction with the historical level and trend of the difference.
