Facebook (FB) shares are surging in the wake of its Street-beating third quarter earnings report. Michael Sansoterra, portfolio manager for the RidgeWorth Large Cap Growth Stock Fund (STCAX), said the social networking giant’s stock - already up 40% in 2015 – has more room to run. 'We think Facebook can continue to grow north of 30% for the next few years,' said Sansoterra. 'They are taking market share from traditional places where advertising go like print media and television. And they are growing their user base.' The RidgeWorth Large Cap Growth Stock fund is up almost 11% so far this year, according to fund-tracker Morningstar. The fund is out performing 90% of its peers in Morningstar’s large cap growth category. Under Armour (UA) shares are up almost 41% thus far in 2015 and is spending a ton to compete with Nike (NKE), yet Sansoterra said the athletic wear-maker has what it takes to stay in the game because of its impressive digital marketing strategy. 'We see a lot of growth opportunity for Under Armour to continue to beat up on Nike, but Adidas more so,' said Sansoterra. Finally, Sansoterra is a fan of Amazon (AMZN), which has seen its shares soar over 110% year-to-date. He said he likes the online e-commerce giant 'primarily for its retail business and their ability to add third party partners.'
