US stocks edge higher

A batch of mixed earnings reports flustered Wall Street yesterday as investors searched in vain for strong evidence of a resurging economy by year’s end. Stocks lurched up and down before ending the session modestly higher.

Strong profits from Eastman Kodak and Amazon.com gave a boost to the Dow Jones industrials and Nasdaq composite, while Sun Microsystems weighed on the Standard & Poor’s 500 index, analysts said.
