As reported earlier today, the Zynga IPO is getting closer and US gaming stocks are rallying in anticipation of it. Zynga’s listing is shifting focus on this sector and increasing investor attention on the potential in the space. Glu Mobile’s share rose 11% in today’s trading session, following a 11% run yesterday. Since last Friday, Glu Mobile’s stock is up some 30%. Shares of Majesco Entertainment closed 12% higher today and are up some 20% since last Friday. Given the upcoming hype around Zynga and Christmas around the corner, this trend is likely to continue.
