Linked in 10% move ahead, time to short?

LNKD just broke below its 8 month trend line and its below the 50 day MA. I predict a kiss of death back to trend and then down to test the 200 day MA as well as its last low of about $187. I'm going short with a stop at the 50 day and a target of $190-$200. With negtive earnings and a forward PE of 78 it doesn't make sense for it to be valued this high. Down we go.
