Google and Groupon are the largest holdings from the United States, each accounting for less than 5% of SOCL's portfolio. LinkedIn, meanwhile, is nowhere to be found among the fund's top ten holdings. Ultimately, for conservative investors, there are other more-liquid and less-top-heavy ways to take advantage of the growing presence of social media. The First Trust Dow Jones Internet Index Fund ( FDN) is one product I've pointed to as being a promising play on this industry. FDN's direct exposure to social media names is limited. However, with extensive exposure to Google, Amazon ( AMZN), eBay ( EBAY) and other Internet household names, the fund is in a strong position to profit as social media helps to further engrain the internet into our daily lives.
