GM said that rather than break even in the current quarter, as it has previously predicted, it will probably lose $1.50 a share before special items.

"Every time we have a down day its because of oil," says Larry Perruzi, equity trader at Boston Company Asset Management. "And today oil had a friend in GM's warning."
