The markets had a quiet week between June 23 and June 27. None of the major market indices ended the week more than 1% away from Monday morning's starting point.

But these three tech stocks clearly never got the order to lay low:

  • Patent portfolio manager VirnetX Holding (NYSEMKT:VHC) surged┬álast Tuesday and then held steady, closing the week 10.8% higher.

  • Digital video processor designer Ambarella (NASDAQ:AMBA) followed a similar pattern, rising as much as 11.3% by Tuesday before sliding back to a more modest 4.8% full-week gain.

  • OLED technology researcher Universal Display (NASDAQ:OLED) did it the other way around, trading sideways or down until last Friday -- when it surged 9% in a single day.
