Where first-quarter profits once were expected to jump 14.8 percent, they are now estimated to contract 1.48 percent, according to the most recent figures compiled by S&P Capital IQ. The second quarter looks bleak as well, with current forecasts calling for a 1.09 percent loss.
For the full year, earnings are expected to grow just 1.91 percent. Even with a customary beat rate of 65 percent to 75 percent, that would result in earnings growth in the low single digits. Initial full-year earnings projections were for 11.5 percent growth.
