That’s odd…. The Dow in Dec 2020 was 30606 in Dec 2024 it was 42544, almost 50% higher. Might be time for a new broker!!! Just kidding
The explanation as I see it, is not the stock market totals per se, but who is reaping the benefit of those totals.
My 401K has weathered some setbacks.. the high tech crash, the dot com bubble (about 2000), the banking crisis (about 2008) when Obama bailed out GM and the banks and left small investors to take the hit.
In both cases honest Joe Public took the hit...and the rich got richer.. No reason to suspect the fiasco Biden put us through, happened any other way..
Certainly the Bidens and other deep staters did OK !
