On the final half day of Barack Obama's presidency, the S&P 500 stock market index closed up slightly at 2,271.31. Counting from this day in 2009, when that same index closed at 805.22, that marks a total gain of over 282 percent. The NASDAQ is up even more: 386 percent. Though that's without accounting for inflation, it's still the largest gain of any president since Dwight Eisenhower in the 1950s, as Reuters demonstrates.
Great news for stockholders, though it's worth noting that median wages have not shown nearly the same upward trajectory. Again leaving aside inflation, they only increased by about 14 percent from 2009-2015 (the most recent data that is available). Ryan Cooper
