Before they buy the calls the buy the stock first and a lot of it. Then they buy the calls and sell there lower price stock that they had been buying ahead of time. When the news comes out that the calls were bought they sell there stock into the run up. So even if the calls become worthless they made a ton of money.
I think the selling is over .Today was the day people sold out and it is going to be steady now.
I would say its only because someone put down money on the calls.Traders jumped in and brought up the stock. That is what those people are counting on. But don't forget the calls can also be worthless if this drops back to $8
