U.S. major stock indexes rose significantly, as the published solid quarterly results of UnitedHealth (UNH), Johnson & Johnson (JNJ) and JPMorgan Chase (JPM) eased concerns about the negative impact of the protracted US-China trade war on US companies.

UnitedHealth announced that it received a adjusted quarterly profit of $ 3.88 per share, which was higher than the average forecast of analysts at $ 3.76. The company's revenue also exceeded market expectations and it raised its profit forecast for the whole of 2019. UNH shares soared 8.31%.

Johnson & Johnson reported quarterly earnings of $ 2.12 per share, compared with analysts' average forecast of $ 2.01. The quarterly revenue of the manufacturer of medical equipment and consumer goods also exceeded the average market estimate, which was mainly facilitated by the growth in sales of medicines and medical devices. JNJ shares jumped 1.62%.

JPMorgan Chase reported quarterly earnings of $ 2.68 per share, which was $ 0.22 higher than analysts' average forecast. The financial institution’s revenues also exceeded Wall Street’s forecasts, driven by growth in mortgages, car loans and credit cards. JPM shares rose 3.17%.
