Global X Social Media ETF (SOCL). ETFs are a great way to play market trends, since they give you exposure to multiple companies that are driving the action but don’t carry the same risk that can come from holding a single name. In SOCL’s case, social media’s biggest names serve as its top 10 holdings, including FB, TWTR and China-based Tencent (TCEHY). Not only does this give you diversification, but some global exposure to this wide-ranging trend. Tencent, for example, is not traded on the U.S. exchanges, so the ETF gives you safe and inexpensive access you otherwise would not have.
