Just had a long and very good call with President Xi of China. Deal is moving along very well. If made, it will be very comprehensive, covering all subjects, areas and points of dispute. Big progress being made!

The two nations previously agreed to a temporary tariff truce at least until March, putting on hold the Trump administration's plans to raise tariffs of some $200 billion worth of Chinese imports from 10% to 25%.

Meanwhile, a Chinese Foreign Ministry spokesman was quoted by the official Xinhua News Agency as saying that "China stands ready to work with the United States to move forward the China-U.S. ties which are underpinned by coordination, cooperation and stability."

2. -- Amazon Reportedly Planning Whole Foods Expansion

Amazon.com Inc. (AMZN - Get Report) reportedly plans to build and expand Whole Foods stores across the U.S. to put more customers within range of the e-commerce giant's two-hour delivery service.

The push would bring Whole Foods to more suburbs and other areas where the company is quickly adding customers since Amazon bought it in 2017 for about $13.5 billion, The Wall Street Journal reported.

Amazon and Whole Foods declined to comment for the Journal on new store construction or spending. In the Rocky Mountain region, one person familiar with the plans told the newspaper that Whole Foods employees have visited potential retail spaces in parts of Idaho, southern Utah and Wyoming, where Whole Foods doesn't have stores now.

Amazon was rising 2.2% in premarket trading on Monday.

3. -- Verizon and Walt Disney Reach Carriage Deal for Fios

Verizon Communications Inc. ( VZ - Get Report) and Walt Disney Co. ( DIS - Get Report) reached a deal over programming fees.
"Verizon and The Walt Disney Company have reached a broad-based distribution agreement. Details will be released in the coming days," the companies said on Twitter on Sunday.
Verizon last week threatened to pull Walt Disney services such as the Disney Channel, ESPN and some ABC content from Fios TV over a money dispute.

Just after Christmas Day, Verizon had emailed Fios customers, saying that "Disney is currently proposing that Verizon pay hundreds of millions of dollars more for its programming, despite the fact that many of its key networks are experiencing declining viewership."

"The rising cost of programming is the biggest factor in higher TV bills and we are standing up to networks like Disney, refusing to accept these huge increases," Fios added.

Without a deal, ESPN and other programming would have been cut from Fios TV by 5 p.m. on Monday.

Verizon was rising 0.9% in premarket trading. Disney shares rose 2%.

4. -- Sears Gets Last-Minute Bid From Chairman

Sears Holdings Corp.  (SHLDQ) -- once famed for its iconic catalog and department stores -- narrowly averted liquidating when Eddie Lampert, the retailer's chairman, made a last-minute, $4.4 billion bid to buy and save the company.

Lampert made the bid through his hedge fund, ESL Investments. No other official bid had appeared by Friday.

ESL said the bid includes $1.3 billion in financing from three institutions. Reports said Bank of America Corp., Citigroup Inc. and Royal Bank of Canada would assist with the financing.Transform Holdco LLC, an affiliate of ESL Investments, said it would purchase 425 Sears stores, offering employment to up to 50,000 of the chain's 68,000 current employees.

The deadline for deciding on "qualified" bidders is Jan. 4, and if a bid by ESL Investments passes that hurdle, an auction would be slated for Jan. 14.

Without an accepted bid from ESL Investments - the chain's largest creditor and shareholder - liquidators would break the company into pieces.  

5. -- Tesla Names Larry Ellison to Its Board

Tesla Inc. (TSLA - Get Report) was up 1.3% in premarket trading Monday after rising sharply Friday following the company's naming of Larry Ellison and Kathleen-Wilson Thompson to its board.

Tesla closed with a gain of 5.61% to $333.87 on Friday.

Telsa said Ellison, the current executive chairman and chief technology officer of Oracle Corp.  (ORCL - Get Report) , was added to the board as was Wilson-Thompson, the global head of human resources at Dow component Walgreens Boots Alliance Inc. (WBA - Get Report) .

The board additions were part of a settlement reached earlier this year between Tesla CEO Elon Musk and the Securities and Exchange Commission that allowed Musk to remain chief executive of the electric carmaker he founded but forced him to step down as chairman.
