Trade war fears have stocks in panic mode on Monday. Here's what to know as a wild week kicks off.

U.S. equities are getting rocked Monday as Washington and Wall Street continue to digest the possibility of a trade war. Treasury Secretary Steven Mnuchin said that the investment restrictions on China reported by numerous media outlets were "false, fake news." Mnuchin said that the investment restrictions, which had earlier been reported to target Chinese investors in the U.S., would instead apply to "all countries that are trying to steal out technology."

That being said, markets experts from Charles Schwab say it's too soon to declare war in trade disputes. According to them, a positive resolution to trade disagreements is possible and would represent a major tailwind for equities. 

And the big-time movers in Monday's session? U.S. Steel Corp. (X) , Netflix Inc. (NFLX) and Carnival Corp. (CCL) .
