Like social media phenomenon Facebook, microblogging site Twitter, too, had a rock star listing but its trajectory post that is a totally different story. FB debuted with a market cap of a little over $100 billion in May 2012 before slip-sliding to $38 billion in early September 2012. Since then, it has only headed north, currently trading at a market cap of $333 billion. Twitter listed in November 2013 with a market cap of $23 billion and rocketed to $40 billion in January 2014. Now, it trades at $10 billion. While FB continues to be liked, investors and analysts continue to rant over Twitter’s lack of flight.
