Stock Market Today: Trump's Swing at China Sends Nasdaq Into Correction

A stock market that was already full of jitters got something a little more tangible to worry about over the weekend, and that spilled out into Tuesday trade that sent the Nasdaq Composite into a correction.

President Donald Trump on Labor Day said America would "end reliance on China once and for all, whether it's decoupling or putting in massive tariffs like I've been doing already." China, meanwhile, announced an initiative to help set global data-security standards -- a counter to America's "Clean Network" guidelines that would exclude some Chinese firms.

Large tech firms took the worst of it, including Tesla (TSLA, -21.1%). Standard & Poor's surprised many market observers by not adding the electric vehicle maker to the S&P 500. Instead, online marketplace Etsy (ETSY), automatic test equipment supplier Teradyne (TER) and health care tech and manufacturing firm Catalent (CTLT) will be elevated as of Sept. 21. Out will be tax preparer H&R Block (HRB), beauty company Coty (COTY) and discount department-store chain Kohl's (KSS).

The tech-heavy Nasdaq Composite finished 4.1% lower to 10,847. The blue-chip index has now dropped 10% in the past three trading sessions, putting it in correction territory (a drop of 10% or more).

Other action in the stock market today:

• The Dow Jones Industrial Average closed with a 2.3% decline to 27,500.
• The S&P 500 lost 2.8% to 3,331.
• The Russell 2000 was the "least bad" major index, declining 2.0% to 1,504.

Know How to Protect Yourself 

If you haven't already, consider reviewing your defensive options. Even if the market isn't looking over a deep cliff like it was in late February, more experts are calling for continued turbulence in the weeks ahead. "Market volatility is returning after months of steady advances in risk assets," writes the BlackRock Investment Institute. "Valuations have risen, and we could see greater volatility in coming months as a result, especially as the U.S. election closes in."

Bonds and gold could yet again act as stores of protection, but it's easier buy both with funds -- these seven gold ETFs allow you to buy either the metal itself or the miners who collect it, while these 12 bond funds provide access to several categories of fixed income.
