Microsoft, however, retains the title of history's most valuable company if its 1999 peak value of about $621 billion were to be adjusted for inflation.
Apple's stock usually rallies in the run-up to major product launches, among the most heavily watched events on the annual tech calendar. The iPhone is the company's biggest product, yielding half or more of its sales.

Facebook rebounded above $20 in afternoon trade after Capstone's upgrade, based on a combination of a more attractive valuation since its decline, and good long-term advertising prospects.
"It seems to be down around levels that people who didn't like the deal thought it was really worth. And now it seems to have stabilized," sad Eric Kuby, chief investment officer, North Star Investment Management Corp in Chicago.
It may have "found a level which seems more of a better price for people valuing the company in terms of the future."
