Though both the S&P and Dow Jones averages rose little on Tuesday, Apple stock rose 1.2 percent to close at $453.32 -- the first time the stock has closed over $450 since mid-May, and on the heels of the revelation that Apple CEO Tim Cook is again in China, talking to current partners and possibly trying to break the logjam that has kept the iPhone out of China's largest carrier, China Mobile. This is Cook's third trip to China since becoming CEO, with all the trips centered on boosting iPhone sales in the region.
