Facebook Acts Swiftly to Fix Loophole and 4 Spotlight Social Media Stocks

Facebook, Inc. (NASDAQ:FB) moved quickly to shut down a loophole making some able to be accessed without a password. This bug was revealed in a message that was posted to the Hacker News website. The message contained a search string that, that when used on Google, returned a list of links to 1.32 million Facebook accounts, and some of these links logged in to the account without the necessary password. All the links revealed email addresses of Facebook users.

Groupon, Inc. (NASDAQ:GRPN) wasn’t doing well even before Sandy reared her ugly head. The company’s stock was the worst-performing U.S. stock with a market capitalization over $1 billion during 2012, but now, it appears as if things have deteriorated. Groupon shares saw a drop of nearly 4 percent on Friday morning to $3.87, which is the lowest level in their history. The stock has fallen 12 percent during this short trading week, and plummeted over 80 percent since Groupon’s initial public offering a year ago gave the company a $13 billion value. On Friday, Groupon’s market valuation slumped $2.58 billion. Considering Groupon’s $1.2 billion in cash, its value has dropped to $1.38 billion, making Groupon arguably the worst of the three large Internet IPO busts of this era. This would also include Zynga and Facebook, which has seen more market value wiped out but continues to be a much stronger company.
