Of the 87 companies in the S&P 500 that have reported results through Monday, about 62.1 percent have topped earnings expectations, according to Thomson Reuters data, compared with the 66 percent average over the past four quarters. On the revenue side, 51.7 percent have beaten forecasts, below the 54 percent average over the past four quarters.
S&P 500 companies' first-quarter earnings are projected to have increased 0.8 percent from a year ago, Thomson Reuters data showed. The forecast is down sharply from the start of the year, when profit growth was estimated at 6.5 percent.
"We are certainly in a wait-and-see mode for earnings which can be volatile and therefore a lot of money is just waiting on the sidelines to see what happens," said Tim Ghriskey, chief investment officer of Solaris Group in Bedford Hills, New York.
"Certainly, companies that confirm the rest of the year guidance, even if they miss the first quarter, it's a good thing because there is still a lot of expectation that we are going to see the economy begin to accelerate and also do some catch-up from the weather-impacted first quarter."
