When Facebook went public May 18 its offering tipped the scales at $16 billion, the second-largest U.S. IPO on record. A bit more than a week later, the social network is leading a slightly more ignominious list.
In terms of market capitalization, Facebook has been the biggest loser since its debut among the companies in the Russell 1000 index, according to Bespoke Investment Group.
From May 18 through Tuesday, Facebook has lost $21.8 billion in market value.
