Plunge in Walmart shares offsets technology stock rally

A steep drop in Walmart's stock and losses in other sectors pulled U.S. indexes mostly lower Tuesday, outweighing gains by technology companies. Slides in grocery store operators and other consumer-focused companies accounted for much of the drag on the market, which was coming off a six-day winning streak. Investors were sizing up the latest quarterly earnings and deal news following a long holiday weekend.
