Buffett always says, if you believe in the potential of a stock, then stick with it and add regardless of pricing. He didn't get as ridiculously rich as he is by short horizon fickle trading. But thanks (to whoever) for the cheaper shares today.
I am long this stock and may add as money is available, but if you think Buffett would touch this stock with a 10 foot pole, you are kidding yourself. Not his model at all. But your point about short term trades is well taken.
