VirnetX Tumbles Despite Gilford Reiteartion

Shares of VirnetX VHC dropped over 10% on Friday despite getting defended at Gilford Securities. The firm reiterated its Buy rating and $65 price target. A jury ruled Thursday that while VirnetX's patents are valid, Cisco CSCO did not infringe upon them. VirnetX has been a controversial company for some time. Along with that controversy, shares have been on a rollercoaster ride: trading as high as $40 and as low as $15. The company is widely known as a patent troll -- the company really makes no products of its own, instead using its patent portfolio to bring lawsuits against major tech companies. Shares of VirnetX traded near $22.70 on Friday.
