Stock Market Update

[BRIEFING.COM] After running into some round number resistance at the 6,400 level, the S&P 500 (-0.9%) finally eclipsed the mark and is now just beneath its session highs, while the Nasdaq Composite (-1.0%) and DJIA (-0.7%) hold similar losses. 

President Trump stated on the Scott Jennings Radio Show that the administration plans to appeal the ruling that declared most of the levies he imposed as illegal, calling the situation an emergency and saying that the country will be in very serious economic trouble without the tariffs. 

Only a small batch of companies report earnings before the open tomorrow, and there are no consequential economic data releases on the docket, leaving the market in search of an additional development to turn attention away from tariff uncertainty and mitigate today's losses.
