No. I think it's other way around. They were priced so high in the first place because they were expected to grow at a very high pace. They have mostly matching those until 15Q4 but the expectations for the next year are drastically lower so they get priced lower. What's so difficult to understand about it.

If you feel LNKD is cheap at this price, it's time for you to go make some money. Buy stock, calls.
