With 2014 just starting, investors may be thinking about which stocks they want in their portfolios throughout the year. In this segment of Two Fools Debate, Fool editor Jamal Carnette and contributor Sam Mattera discuss whether investors should own Twitter (NYSE:TWTR) in 2014.

Sam thinks Twitter remains an exciting business. Although it rallied tremendously after IPO, it's given back much of its recent gains in just the past few weeks. Sam thinks Twitter has become an integral part of the Internet, and its treasure trove of meta-data gives its platform value.

In contrast, Jamal thinks Twitter's present valuation is just too excessive. While he acknowledges Twitter's unique place in the Internet space, he thinks investors will get an opportunity to purchase shares at a more reasonable valuation at some point in the future. While Twitter may be growing its revenue, much of that growth is likely already baked into the stock at these levels.
