In a “broad 2011 rally that pushed the Dow up nearly a point in mid-morning trading Monday, Apple popped more than $7 (2.25%) to hit new record intraday highs — and to cross a major psychological barrier,” reports “Fortune” (http://macte.ch/Jelq1).

The company’s market capitalization — its stock price times the number of shares outstanding — is now more than $300 billion. Apple has been the most valuable tech stock and the world’s second most valuable company — after ExxonMobil — since it passed Microsoft last May.
