Here are five things you must know for Tuesday, Nov. 26: 

1. -- Stock Futures Suggest a Mixed Start for Wall Street

U.S. stock futures were mixed Tuesday amid renewed signals of progress in U.S.-China trade talks and an upbeat assessment on the domestic economy from Federal Reserve Chairman Jerome Powell.

China's Commerce Ministry said in a statement Tuesday it had made progress with its U.S. counterparts, including U.S. Trade Representative Robert Lighthizer and Treasury Secretary Steve Mnuchin, during a phone call late Monday and agreed to work toward implementation of the so-called phase one agreement.

The positive tone from Beijing followed a weekend move by China to overhaul its legislation on intellectual property protection, which many analysts have said suggests a willingness to reach an acceptable agreement with the United States ahead of planned tariffs on $160 billion in China-made goods, which are set to kick in on Dec. 15.

Powell, meanwhile, presented an optimistic view on the strength of the U.S. economy during a speech to the Greater Providence Chamber of Commerce in Rhode Island. Focusing on the labor market, Powell said Monday it was possible for wages to continue to rise, even with unemployment running at five-decade lows. He also signaled that continued low inflation means the central bank won't be hiking interest rates anytime soon.

Contracts tied to the Dow Jones Industrial Average fell 1 points, futures for the S&P 500 were down 0.70 points, and Nasdaq futures declined 1.75 points.

Stocks finished strong Monday, with the three major indexes ending at record highs, boosted by trade optimism and a wave of merger deals.

The Dow rose nearly 191 points, or 0.68%, to 28,066.47, the S&P 500 finished up 0.75% to 3,133.64, and the Nasdaq was up 1.2% to 8,632.49.

3. -- Alibaba Rises Nearly 7% in Hong Kong Trading Debut

Hong-Kong listed shares of Alibaba Group (BABA) - Get Report , the Chinese e-commerce giant, rose nearly 7% in their first day of trading Tuesday.

The stock closed at HK$187.60 ($23.96), up 6.6%, and had risen as high as HK$189.50 during the session.

Alibaba priced 500 million shares in a secondary offering at HK$176 (US$22.48) last week, raising HK$88 billion (US$11.2 billion). It's the richest initial public offering of the year, at least until Saudi Aramco goes public in Saudi Arabia.

The company's shares already are listed in New York, where it raised $25 billion in 2014 in the largest initial public offering in history.

Charles Li, executive director and chief executive of Hong Kong Stock Exchanges, praised the company for carrying out the listing despite the political unrest in Hong Kong.

"I am very thankful that Alibaba, after five years of traveling afar, finally came home. I'm also grateful that they choose to come despite the difficulties, despite the challenges that we are going through here in Hong Kong," Li said.
