You clearly don't understand that they normed the chart to the first trading day post Biden inauguration. Nothing else was stated.
If you'd bot stock on Trump's inauguration you would have lost money three years later.
I understand exactly how to read a chart.
These are the facts.
Fact, From Jan 20 2017(Trump's inaguration) to jna 6, 2020. The SP500 returned 43%.
Fact From Jan 21 2021(Biden's inaguration) to Jan 6, 2024. The SP500 returned 23%.
DEAL WITH IT.
