"Excluding special items, GM earned $0.17 a share in the first quarter, a far cry from the $0.87 Wall Street was expecting and the $0.62 GM earned during the same period last year..."

I'm surprised the stock was only down 5%. If it were a tech stock, to miss by that much would cause a stock to be cut in half or even more. Some companies fall sharply for just meeting expectations or not beating them by enough.
