Stocks on Wall Street started in the red on Black Friday as another tumble in oil prices weighed on energy stocks.
The stock market has a holiday-shortened trading day following Thanksgiving, with the closing bell coming at 1 PM ET (18:00 GMT).
The Dow fell 0.7%, while the broader S&P 500 index lost 0.65%. The tech-heavy Nasdaq composite slid 0.41%.
Crude oil prices fell more than 6% as concerns persisted about a supply glut. Dow components Exxon Mobil (NYSE:XOM) and Chevron (NYSE:CVX) fell at the open.
Meanwhile, retail stocks will be in focus with Black Friday sales underway. Discounts will continue through to Cyber Monday as investors will look to see if the companies can overcome an underwhelming retail earnings season.
Investors will also be focusing on the G20 summit in Buenos Aires, where U.S. President Donald Trump and his Chinese counterpart Xi Jinping are expected to hold talks amid a worsening trade dispute between the two countries that has weighed on financial markets and sparked fears of a global slowdown.
The high-stakes meeting comes as the Trump administration shows little sign of backing down in its demands and rhetoric. Chinese Vice Commerce Minister Wang Shouwen said on Friday that trade talks should be equal and mutually beneficial.
Adding to worries, The Wall Street Journal reported that the U.S. government was trying to persuade wireless and internet providers in allied countries to avoid telecommunications equipment from China's Huawei Technologies.
