Wall Street resumes its slide

Wall Street tried but failed today to extend a one-day rebound, but succumbed to late selling on questions about AOL Time Warner’s accounting and pessimism about second-quarter earnings reports.

The Dow Jones industrial average had its sixth triple-digit loss in nine sessions, while the Standard & Poor’s 500 index closed below 900 for the first time in nearly five years. Analysts said the pullback reflected investors’ continuing lack of confidence.
