Stocks plunged Tuesday as investors, nervous about upcoming earnings reports, cringed at troubling forecasts from retailers Home Depot and Sears and at soaring oil prices. The Dow Jones industrial average fell 148 points.

The market seemed to be following the pattern of previous earnings seasons, turning lower as second-quarter reports had a rocky start. Home Depot Inc., Sears Holdings Corp. and homebuilder D.R. Horton Inc. offered dreary outlooks that suggested the sluggish housing market may dampen consumer spending.

The outlooks followed Monday’s news that aluminum producer Alcoa Inc.’s second-quarter sales missed estimates and that printer manufacturer Lexmark International Inc. slashed its second-quarter earnings forecast. Together, the reports dispirited investors who had been counting on corporate America’s performance giving a boost to the stock market, which has been stuttering in recent weeks. (AP)
