Quarterly corporate earnings have put investors in a positive mood.

While it's still early to draw any final conclusions, second-quarter results have come in better than most analysts had expected.

U.S. stock futures were higher Tuesday.

"The overall tone in the market is still very positive," said David Jones, chief market strategist at IG Markets in London. "Any weakness does not last very long."

U.S. stocks finished mostly flat Monday, though the S&P 500 gained 0.2%, squeaking past its record high by one point.

All three major U.S. indexes are up roughly 19% so far this year.

Earnings parade: UPS (UPS) reported earnings in line with its preliminary expectations. The packing and shipping company said volume in the U.S. and internationally grew, even as revenue came in slightly below forecasts.

Travelers (TRV) reported a boost in quarterly profit , citing "lower catastrophe losses."

DuPont (DD) reported earnings that beat forecasts but revenue fell short, which the company blamed on slipping chemical sales and economic headwinds in Europe and Asia.

Nearly 160 companies in the S&P 500 are slated to report quarterly results this week overall.
