GSV Capital ( GSVC) is an externally managed, non-diversified closed-end management investment company. This stock is trading up 6.5% at $18.91 in recent trading. Today's Volume: 996,000 Average Volume: 796,434 Volume % Change: 108% Shares of GSVC are skyrocketing today after Ascendiant Capital initiated coverage on the stock with a buy rating and a $20 price target. The analyst said GSVC's two largest investments are Twitter and Facebook, and the upcoming IPO for Facebook could be a catalyst to drive the stock higher if Facebook's valuation is above $110 billion. From a technical perspective, GSVC is soaring here on above average volume, and the stock is quickly moving within range of a major breakout trade. That trade will hit once GSVC takes out some past overhead resistance at $20.39 to $20.89 with high-volume. Traders should now look for long-biased trades off a sustained move or close above those levels on volume that's near or well above 796,434 shares. If we get that action soon, then GSVC will be trading in all-time high territory and the stock could easily hit $25 or higher very quickly.
