Heh, I had the same idea and lost a bit (if I had a proper account I woulda made enough on the volatility but that's another issue). A year ago I'd have though that by late 2013 LNKD'd would have fallen.

Look what happened last month. P/E insane, stock at $200. LNKD releases decent numbers ("as expected, LNKD exceeded expectations"), and the market decides "yeah let's just keep that P/E at the same spot".

As someone else wrote, the market can stay irrational longer than you can stay solvent. Maybe if LNKD releases a "met expectations" or "missed by 1%" people will realise a 900+ PE is ridiculous and it'll tank.

Meanwhile, LNKD would be idiotic to not sell off some more shares.
