Here are five things you must know for Wednesday, Nov. 20: 

1. -- Stock Futures Tumble on Doubts Over U.S.-China Trade Negotiations

U.S. stock futures fell Wednesday after China condemned a U.S. Senate resolution supporting human rights in Hong Kong and Donald Trump again threatened to increase tariffs if Washington and Beijing aren't able to negotiate a near-term trade agreement.

China's displeasure with the Senate resolution, known as the "Hong Kong Human Rights and Democracy Act," comes at a sensitive juncture in the trade negotiations following reports from China-backed media that Beijing won't accept an agreement that doesn't include the cancellation of tariffs from Washington.

Chinese Foreign Ministry spokesman Geng Shuang said the Senate move was designed to "bolster anti-China, extremist and violent radicals who attempt to disrupt Hong Kong," and cautioned that "all those attempts to interfere in or impede China's development will be in vain."

Trump, meanwhile, told a cabinet meeting Tuesday that "if we don't make a deal with China, I'll just raise the tariffs even higher." The president added China would need to offer a deal "I like" in order to complete the first phase of the the negotiations.

Contracts tied to the Dow Jones Industrial Average fell 111 points, futures for the S&P 500 were down 12 points, and Nasdaq futures tumbled 43 points.

The Nasdaq closed at another record high Tuesday, the only one of the three major stock indexes to finish in positive territory, as disappointing sales forecasts from Home Depot (HD) - Get Report and Kohl's (KSS) - Get Report , along with ongoing concerns about a U.S.-China trade agreement, pulled shares lower.

The Nasdaq rose 20.72 points, or 0.24%, to close at 8,570.66. The Dow sank 102.20 points, or 0.36%, to 27,934.02, while the S&P 500 slipped 1.85 points, or 0.06%, to 3,120.18.

Trump will visit the Austin factory where Apple contractor Flex Ltd. assembles some of the company's laptops. Treasury Secretary Steven Mnuchin and White House economic adviser Larry Kudlow are expected to accompany Trump.
