You are assuming insiders dump the stock. Obviously you don't have a finance job with that kind of analysis.Quote from ksmetana:
FB's PE is ~106. Look out below.
You probably have some shorts covering as the insiders panic sell. It is a good opportunity to get filled.
This stock is ready to collapse, hard, insiders who hold are going to lose a large percentage of their value.
Can FB be successful? Will it get bought out? Maybe, but it doesn't belong anywhere near $20 a share.
Holders are going to dump this stock, and the street is going to steal this company.
