• U.S. stocks jumped on Monday as shares of some beaten-down tech companies rebounded after posting steep losses last week while General Motors shares climbed.

The Dow Jones Industrial Average rose 354.29 points to 24,640.24, posting its biggest gain since Nov. 7, while the S&P 500 gained 1.55 percent to end the day at 2,673.45. The Nasdaq Composite outperformed, rising more than 2percent to close at 7,081.85.

Shares of Facebook, Amazon, Apple, Netflix and Google-parent Alphabet all rose at least 1 percent. These stocks dropped more than 3.6 percent last week, falling further into bear-market territory.

Monday's moves come after stocks suffered their worst Thanksgiving week since 2011 last week as a sell-off in once-loved technology stocks and oil prices put traders into risk-off mode. On Friday alone, U.S. oil prices plunged about 8 percent.

• Investors also looked ahead to a speech from Federal Reserve Chairman Jerome Powell later this week. Powell is scheduled to speak at the New York Economic Club on Wednesday. During this recent sell-off, investors have been worried about the future of monetary policy. The Fed is expected to hike rates in December after tightening policy three times earlier this year. For next year, the Fed expects to hike rates three times.

• Politics will be another area of focus for investors this week, with the G-20 summit in Argentina and Brexit dominating headlines. The meeting of the world's most powerful leaders will bring together President Donald Trump and Chinese President Xi Jinping, at a time of intense trade tensions between the two countries. Meanwhile, the U.K. has gained the backing of the European Union on its deal to withdraw from the soon-to-be 27-member bloc.

• European stocks rallied Monday afternoon, as investors digested fresh developments surrounding the U.K.'s withdrawal process from the EU.

• The pan-European STOXX 600 closed provisionally up 1.27 percent, with most major bourses trading sharply higher. Across the board, sectors showed a positive picture with banks, autos, and insurance leading the way.

• Asia markets were up in early trade on Tuesday after an overnight bounce on Wall Street while investors await a crucial meeting between President Donald Trump and Chinese leader Xi Jinping.

In Japan, the Nikkei 225 rose 0.35 percent while the Topix index added 0.5 percent. South Korea's Kospi index was up 0.27 percent.
