Really  

As explained to you once before, investors invest toward the future.  If the market is moving down, then the future does not look that great.

Market did not rally when Biden came into office.  Trumps last year had a financial return in the market of 31.21%, Biden first year was 18.02%.  Now the financial return is negative.  In fact Trumps last year had a GDP of plus 32%, numbers Biden will never achieve.

Inflation, and economy stagnation did not start until Biden took over, he caused both!  Every person from the right has explained to you how Biden created the inflation, each one!   Not going to do it again, if you can't understand what is real, why should I proceed.  Just read some prominent economic articles.
