The first quarter ended on Friday, and it was a banner quarter for all the major indexes. The S&P 500 index gained 5.5 percent, its strongest first-quarter performance since 2013 and the best gain it's posted in any quarter since the fourth quarter of 2015.
The Dow Jones industrial average was up 4.6 percent over the past quarter. That marks the sixth consecutive quarterly gain for the Dow, the longest such stretch since the fourth quarter of 2006.
After all that, though, the Nasdaq was the best performer of all the major indexes, returning a nearly 10 percent gain over the past quarter. That's its best quarterly performance since the end of 2013.
