The Dow actually went up significantly under Trump when adjusted for inflation. From 25,644 on January 2017 to 35,949 on January 2021. That's an increase of 40%. Under Biden, the inflation adjusted Dow Jones went from 35,949 on January 2021 to 39,869 today (as per

So under Trump, we had 4x the real stock market growth we've had under Biden in almost the same time frame. And the only real growth seen throughout Biden's term was during the first year where most of his economic policies weren't even propagating through the economy yet. Other than that it's just been downhill and getting back to the peak in 2021.
Is there anything else you would like me to school you in?
