Facebook workers, several other others in tech, in an IPO funk

Facebook employees have lost an estimated average of $2 million each in stock or stock options, and employees of several other Silicon Valley tech companies are feeling similar pain.
The Wall Street Journal says Silicon Valley is in a “stock funk,” with employees at Facebook, Groupon, Zynga and Pandora losing $9 billion between them since they went public. (Facebook is the only company actually headquartered in Silicon Valley: Zynga is in San Francisco, Groupon is based in Chicago


 and Pandora is in Oakland.)
By far, Facebook’s employees have lost the most: $7.2 billion. The average nonexecutive employee still has about $2.5 million in options, but has lost $2 million since Facebook’s IPO in May, according to the Journal.
Zynga employees have collectively lost $1.4 billion in stock value since its IPO.
Mountain View-based LinkedIn, on the other hand, has been a good bet for its employees. The value of LinkedIn employees’ equity has tripled, from an average of $310,000 at its IPO last year, to $922,000.
