Dow is more reliable in measuring the market sentiment

S&P 500 and Nasdaq all these indexes broke the top that reached in February 2020 even with all uncertainty and the bad data provided by companies earning during the pandemic, except DOW 30. This index alone proves that the market is weak and once it reached near to the top that made in February 2020 the market start going down bring with it all other indexes. For me, I think right now the DOW 30 is more reliable to measure the market sentiment than S&P 500 even if the first just has 30 companies than the last one which has 500 companies. Because the 30 companies in dow 30 are the strongest companies in the US Economy.
