Prices of stocks change based on new information, so as soon as obama was elected the markets “priced in” expected changes to policy.
Same as how the stock market dropped when news of covid hit, before a single store got closed down.
Ignoring the fact that everyones portfolios had just lost a third of their value is misleading at best.
Unless you were fortunate/brave enough to have money to invest near the bottom of the market and held it until Trump won the election, you didn’t see a dime of those gains. You just watched your portfolio take 5 years to make it back to where it was.
Whereas with Trump no matter when you got into the stock market your portfolio is at an all time high. Even the low of the covid scare was higher than Obamas high point.
Trump reversed a similar drop in less than 6 months. The lockdowns are still going in some of the biggest economies of the country too, Cali, NY, NJ, WA.
Once those end and stop dragging the economy down the economy is going to skyrocket.
