Yes, I find your observation interesting. I shorted linked in because I thought it was driven up excessively by mm's who bought it when fb was pre ipo because it was a way to get in on social media early. Then the fb ipo was a mess, so social media is no big deal, so why is lnkd still selling above 100? And now it seems like a good fb day (and I think fb is a company with many more positive potential upsides than lnkd, who has been around forever) is a good lnkd day. But without markets we wouldn't have mysteries.
