The stock market just finished a relatively uneventful week. The S&P 500 index gained 1.2%, the Dow Jones Industrials lost 0.7%, and the tech-heavy Nasdaq Composite market barometer rose 0.8%.

But some tech stocks were dealt a much tougher hand this week, and their stocks fell 15% or more.

Tableau Software (NYSE:DATA) and VASCO Data Security International (NASDAQ:VDSI) reported strong earnings with solid guidance but still got drastic haircuts. Yelp (NYSE:YELP) kept growing but showed signs of fundamental issues with its business model.

Want to dig deeper into these unfortunate tech stocks? Can any of them roar back to full health? You'll find some answers in the following slideshow.
