These 10 Nasdaq Stocks Are the Index's Best Year-to-Date Performers

Anyone who did not "sell in May and go away" has likely enjoyed stock gains – especially in Nasdaq stocks.

Indeed, the Standard & Poor's 500 Index closed at 1,920 on Thursday, logging its 13th all-time high of 2014. As we close out May, the broad-based benchmark has soared nearly 2%, putting gains since the start of the year at 3.9%.

The Dow Jones Industrial Average, meanwhile, has mostly traded sideways this month. Still, the blue-chip index is on pace to end May in positive territory. It's up a modest 0.7% so far in 2014.

But, it's the Nasdaq Composite sporting the most intense rebound after two months in the red. The Nasdaq fell 4.2% from January to mid-April, but is up nearly 6% since then.

Following are 10 stocks that helped propel the Nasdaq higher recently. A common theme among the bunch is that they all fit into the micro-cap or biotech sectors. Additionally, almost all were spotted earlier this year by Money Morning.
