V dropped a whole bunch lately while the overall market ranged around. V is not subject to credit card defaults so all the bad news does not fundamentally affect it.
Most importantly (and pay close attention to this): More people wanted to buy V today than wanted to sell it.
If you're a long term investor V is priced at a nice dip in a long term uptrend.
If you're a day trader, V went up and down today, giving you equal opportunity trading.
