Let's take a look at LNKD:
LinkedIn only did $189 million revenue in the last reported quarter while trading at a valuation of $11 billion - PPS a tad high? The last "hope stock," so is it worth jumping into prior to earnings? LNKD certainly doesn't behave like the others, since the targeted audience is mostly professionals (people with jobs) but could still be a risky play considering how high the valuation is.
I've been flipping LNKD from $100 to $105 for several months now, but due to the recent plunge of Facebook after earnings, I might stay away from this one on the day of earnings (Thursday).
I'm currently in at $100, with a sell target at $105, so hopefully it will hit that mark by Thursday.
