So, they had a p.r. disaster. Big deal. It's not worth the loss of half their stock value. The company's business is still solid. Investors will come back.
As someone who did sell the stock, I would say there are SOME of those things DO effect the value of the company. Because of the handling of the rise in prices, MORE customers left than they had thought, some turning to other services. AND now that they are losing STARZ, that's a sizable chunk of content.
And the guy that's in charge... he's driving the car very poorly. I think investors will come back... slowly... but the mistakes this year aren't something to just ignore.
