July has been kind to the U.S. stock market even amid escalating trade tensions and rounds of tech sell-off. Dow Jones recorded the largest monthly gain of 4.7% since January while the S&P 500 and the Nasdaq Composite Index logged in the fourth consecutive monthly gains of 3.6% and 2.2%, respectively.

A string of earnings and revenue beats drove the markets higher. Additionally, accelerating economic growth and reports of renewed trade negotiations between the United States and China added to further strength.
