Here are five things you must know for Wednesday, July 25:   

1. -- Stocks Fall Ahead of Trump-Juncker Summit

U.S. stock futures traded lower on Wednesday, July 25, as investors continued to focus on the strength of the corporate earnings season and a key summit on trade between Europe and the United States was set to begin in Washington.

Contracts tied to the Dow Jones Industrial Average I:DJI   fell 96 points, futures for the S&P 500 I:GSPC  fell 5.50 points, and Nasdaq I:IXIC futures were down 9.25 points.

European Commission President Jean-Claude Juncker will lead a delegation from the 28-member EU to the U.S. as he attempts to broker an impasse with the Trump administration on trade and tariffs that began earlier this year when the White House imposed import levies on steel and aluminum.

Reports have suggested the EU was prepared to expand its own list of tariffs on U.S.-made goods, which has already topped €2.8 billion, if it's not able to advance talks with the U.S. president.

The economic calendar in the U.S. on Wednesday includes New Home Sales for June at 10 a.m. ET, and Oil Inventories for the week ended July 20, at 10:30 a.m.
