About 7 months ago, I put out a chart from Bloomberg showing the US SP500 performance over the years of different presidential terms. The chart goes all the way back to 1929.
People generally like to argue about whether it is better for markets when there is Democrat in the Whitehouse, or a Republican. While there are many factors at play, the answer is still not what you think. The chart has now been updated to include the 4 year Trump presidency. Have a look below, and now argue amongst yourselves :)
