"Based on the analysis provided above I may conclude the LNKD is overvalued and is a good candidate for SELL SHORT at current market price levels. "

Even Apple Inc. (AAPL) is overvalued.
Perhaps LinkedIn is in the same road as:
Pandora Media, Inc. (P)
Yelp, Inc. (YELP)
Groupon, Inc. (GRPN)
Twitter, Inc. (TWTR)
Zynga, Inc. (ZNGA)
MeetMe, Inc. (MEET)
even
IAC/InterActiveCorp (IACI)
They seem to be deflating bubbles.

There is a large dotcom bubble fueled by venture investment funds, investors who are dragging other investors to continue investing until they can sell shares of the company and recover leveraged money, but the last holder of shares is going to lose.
