Analysis conducted by SunDial Capital Research expert Jason Goepfert reveals that the stock market's response to President Trump since the inauguration is amongst the weakest since 1950. Within the first 50 trading days after Inauguration Day, the S&P 500 index has fallen by approximately 6.4%. This places it as one of the worst starts compared to other presidents, with Richard Nixon and George W. Bush having even worse starts.

On the contrary, presidents like John F. Kennedy, Barack Obama, and Bill Clinton had strong starts in their first 50 days in office. Goepfert cautioned that historically, rough beginnings have led to negative median returns six months later, with even year-end returns remaining flat or declining in most cases.

While it is not common to attribute stock market movements solely to political factors, the correlation in this case seems evident in response to the new administration's stance on tariffs. The market has reacted negatively to potential tariffs despite other perceived business-friendly policies. The uncertainty surrounding the impact of tariffs has investors and analysts wary about the economic implications and potential further declines in stock prices.
