AAPL breaks all-time high ... again

I don't know if anyone else noticed, but shares in Apple, Inc. have reached another all-time high price.

Just minutes ago, AAPL was at US$428.40, although as usual the stock price will probably wobble all over the place before the close. Why is AAPL doing so well? There is mucho speculation that the company will announce record earnings ... again ... on Tuesday, there's a lot of interest in tomorrow's education / textbook announcement, and many related companies (suppliers and mobile carriers are the prime examples) are reporting increased earnings based on sales of Apple products.

At press time, Apple's market capitalization was at $397.97 billion. Yowza.
