Yeah, I would like to see someone justify the market value of LinkedIn. They seem to be losing money, and they have over 9000 employees (doing what exactly?).

Many people in those xxx headcounts in large companies are in business development.

I might be reading the wrong, but they seem to have been losing money the first three quarters of 2015: http://www.google.com/finance?q=NYSE:LNKD&fstype=ii

They would need to make a pretty good profit the last three month of 2015 to make up for it.

Again I might just not know how to read financial statements, but adding up all the "Net incomes" gives you around $108 million in lose.

They have posted a small loss ($8mn) in the fourth quarter. But if you ignore a number of costs you can easily convert a $166 million loss into a $373 million gain. See the last table in the press release:

That depends on your definition of "losing". Ignoring stock based compensation (almost 20% of revenue if properly accounted for using GAAP) helps to get the "adjusted" net income into positive territory.

I wish I could run my life while ignoring certain pesky costs!
