The bull market turned 2,115 days old on Tuesday, meaning it's been going longer than SnapChat and Tinder -- combined.
Since bottoming out at 666 on March, 9, 2009, the S&P 500 has surged over 200% and is now trading above 2,000.
The bull run is the fourth-longest since 1928, according to Bespoke Investment Group. It would have to last another six-and-a-half years before exceeding the longest bull market ever, the one that spanned December 1987 to March 2000.
