Oct 15 (Reuters) - Wall Street gained 1% on Tuesday as strong earnings from JPMorgan, UnitedHealth and Johnson & Johnson allayed concerns about the fallout from a prolonged U.S.-China trade war on corporate America.
Shares of JPMorgan Chase & Co hit a record high after the largest U.S. bank by assets blew past Wall Street estimates for third-quarter profit.
The bank's results lifted the S&P 500 banking sector to its highest level in more than 2-1/2 months. Goldman Sachs was the only major U.S. bank trading lower after posting a weaker-than-expected quarterly profit.
UnitedHealth Group Inc was set to post its best day in more than a decade, while Johnson & Johnson shares eyed their biggest one-day percentage gain since January after both companies raised their profit forecasts.
The stocks were among the top boosts to the S&P 500 and Dow Jones indexes, and lifted the S&P healthcare sector to a three-week high. Eight of the 11 major S&P sectors were higher.
"If this earnings season turns out to be better than expected, we can end up with a scenario that there won't be pressure on the labor market and that keeps us away from a recession," said Phil Blancato, chief executive of Ladenburg Thalmann Asset Management in New York.
Analysts have forecast the worst quarterly profit performance in about three years for S&P 500 companies, with industrials among those most at risk from the trade dispute.
