Here are five things you must know for Tuesday, Aug. 20: 

1. -- U.S. Stock Futures Turn Lower

U.S. stock futures turned lower on Tuesday and global shares were mixed a day after the decision from the United States to grant China's Huawei Technologies a three-month extension to buy parts from U.S. companies was looked upon as a sign of progress in the trade war between the world's two largest economies.

Contracts tied to the Dow Jones Industrial Average fell 25 points, futures for the S&P 500 declined 2.20 points, and Nasdaq futures were down 3 points. 

"While it is not unexpected, the extension for the easing of Huawei sanctions had added to the relief for markets at the start of the week," said Jingyi Pan, a market strategist for IG in Singapore.

Stocks rose for a third straight session Monday after Donald Trump said the U.S. and China were "talking," and as Trump and other White House officials played down recession fears.

"We're doing tremendously well. Our consumers are rich," Trump said. "I gave a tremendous tax cut and they're loaded up with money."

The economic calendar in the U.S. on Tuesday is quiet.

3. -- State Attorneys General May Probe Big Tech - Report

State attorneys general are discussing launching their own antitrust probe of big technology firms such as Facebook (FB) - Get Report and Alphabet's (GOOGL) - Get Report Google unit, The Wall Street Journal reported, citing people familiar with the situation.

The formal effort could get underway as early as September, according to the Journal. It's likely to focus on whether a handful of dominant technology platforms use their marketplace powers to stifle competition, the Journal said.

While the specific number of states that might join the investigation couldn't be learned, one person familiar with the effort told the Journal that up to 20 or more may participate.

The Department of Justice earlier this summer launched its own review of antitrust issues surrounding tech companies. The Federal Trade Commission also is investigating Facebook.

Separately, FTC Chairman Joseph Simons told the Financial Times that breaking up Facebook would be difficult to do, especially if the company ties together its three major platforms: WhatsApp, Instagram and its traditional newsfeed.

 jumped 8.49% to $113.07 in premarket trading Tuesday after the Chinese search giant's second-quarter earnings fell 62% but still topped analysts' estimates.

Baidu posted second-quarter profit of 2.41 billion yuan ($342 million) compared with a year earlier. Revenue of 26.33 billion yuan, up 1.4% from a year earlier, beat analysts' forecasts.

Adjusted earnings in the quarter were $1.47 per ADR, topping expectations of 88 cents.

"Our focus on strengthening Baidu's mobile ecosystem through knowledge-based content, BJH accounts, smart mini programs and managed pages on Baidu's platform is translating into better user experience, stronger traffic growth, and, we believe, ultimately higher conversion for our customers," said Robin Li, Baidu co-founder and CEO.
