Since being added to the STI Next Wave portfolio last June at a price of $3.00, online gaming company Zynga (ZNGA) has struggled to live up analysts’ expectations after it hired a high-profile Microsoft exec – Don Mattrick – to lead the company. As a result, the board is bringing back former CEO and company co-founder Mark Pincus to turn things around, but that will probably take a while. For that reason we are removing Zynga from our portfolio as we do not see the opportunity for improved operating performance in the near term.
