As with so many things in life, there is also no logic in beheading Americans and picking a fight with the US by Isis, unless they have serious delirious "virgin based" death wishes.
So too, today's MVTG sell makes no sense either. I bought the last MVTG dump like today's and I still have every share of MVTG I bought the last 5 years. That is why I keep a bid up on all stocks I want to buy more of if they ever do a swan dive. But in my experience days like today are very rare with MVTG, like once a year and thus a hard way to buy any real quantity of shares.
