US stocks rose about 1 percent on Tuesday, helped by gains in technology companies and as strong earnings from Netflix and UnitedHealth boosted optimism over what is expected to be the strongest earnings season in seven years. Netflix shares rose 10 percent to hit an all-time high after the video-streaming pioneer smashed analysts' quarterly subscriber estimates.
UnitedHealth jumped 3 percent after the largest US health insurer raised its earnings forecast and posted results that beat Wall Street estimates. Analysts expect profits of S&P 500 companies to rise 18.6 percent in the first quarter, the biggest increase in seven years, according to Thomson Reuters data.
"Being able to surprise on the upside in the phase of higher expectations would be a real sign of strength," said Willie Delwiche, investment strategist at Robert W. Baird in Milwaukee. Hopes about a strong reporting season have helped divert attention from geopolitical and trade worries, which have roiled the markets in recent months.
At 12:36 am ET the Dow Jones Industrial Average was up 0.88 percent at 24,789.21. The S&P 500 rose 1 percent to 2,704.74 and the Nasdaq Composite gained 1.67 percent to 7,275.82.

Data on Tuesday showed US homebuilding increased more than expected in March amid a rebound in the construction of multi-family housing units. The PHLX housing index rose 1.12 percent.
Ten of 11 major S&P sectors were higher, led by the technology index's 1.9 percent gain. The consumer discretionary index rose 1.64 percent, boosted by Netflix and Amazon, which gained 3.2 percent.
