Apple stock is up four percent today. As I type this, Apple’s market cap is $146 billion; compare and contrast: HP ($134 billion), Intel ($149 billion), IBM ($160 billion), Google ($190 billion), Microsoft ($280 billion).

Lately, the correlation between AAPL stock run-ups and actual news regarding Apple is zero. Whereas most of the time there is any actual news — even news that strikes me as unambiguously good news for Apple — the stock goes down.
