The S&P 500 swooned a bit this week, losing 0.9% between Monday morning and Friday night. But the tech sector did better.

57% of the 577 tech stocks I sampled for this article traded up this week. Here's a handful of the most interesting tech winners on Wall Street:

  • Industry giant Intel (NASDAQ:INTC) sees key markets bouncing back from a couple of lean years.

  • Data analysis expert Splunk (NASDAQ:SPLK) received a couple of much-needed positive analyst notes.

  • High-tech materials vendor GT Advanced Technologies (NASDAQOTH:GTATQ) rode its widely covered supply deal with Apple (NASDAQ:AAPL) once again, but also signed an entirely new contract overseas.
