Investors are facing a busy day both on the data and the corporate front, with second-quarter results set to come through thick and fast.

The highlight among the economic news is expected to be the June inflation report, due at 8:30 a.m. Eastern Time. It is forecast to show consumer prices rose 0.3% in June, slower than the 0.4% reported in May. Rising gasoline and food prices likely drove the expected increase in consumer prices, according to economic forecasts.

During the same period a year ago, Apple earned a pre-split $7.47 a share.
