Here are five things you must know for Monday, Nov. 28:

1. -- U.S. stock futures pointed lower Monday as crude oil gyrated after Saudi Arabia pulled out of a meeting with Russia and other large non-OPEC producers ahead of an OPEC meeting on Wednesday in Vienna.

With the Saudis not attending Monday's meeting with Russia, hopes faded that an agreement on production cuts could be reached in Vienna.

"Speculation that OPEC would agree to production cuts spurred big increases last week, and we'll get this kind of back and forth until we get clarity on what exactly the deal is likely to be," Ian Williams, a strategist at brokerage Peel Hunt, told The Wall Street Journal.

Oil prices Monday slipped 0.1% to $46 a barrel in volatile trading. Crude oil fell 3.2% on Friday.

European stocks traded lower across the board Monday after a mixed session in Asia. A weaker U.S. dollar kept a lid on gains in Japan but boosted other markets around the region.

Stocks in the U.S. scored new records with slight gains on Friday in a quiet post-Thanksgiving session.

The economic calendar in the U.S. on Monday includes the Dallas Fed Manufacturing Survey for November at 10:30 a.m. EST.

2. -- Schlumberger  (SLB) , the world's largest oil driller by market value, said Sunday it had signed a preliminary deal to study an Iranian oil field, the Journal reported.

The contract is one of the most prominent signed since Donald Trump won the U.S. presidential election on Nov. 8, according to the Journal. Trump has vowed to undo a nuclear pact with Tehran signed last year by global powers.

A spokesman for Schlumberger told the Journal it has signed a memorandum of understanding with the state-run National Iranian Oil Company "for the non-disclosure of data required for a technical evaluation of a field development prospect."

3. -- Cyber Monday, the Monday after Thanksgiving, is traditionally the busiest online shopping day of the year. But with stores releasing Internet deals earlier, more and more shoppers decided to skip the mayhem at brick-and-mortar locations and purchased goods online.

Consumers spent $3.34 billion shopping online on Friday, a 21.6% increase from the same day last year, according to Adobe Digital Insights.

However, a few retailers, like J.C Penney (JCP)  and Target (TGT)  , saw strong starts to the holiday shopping season at their store locations. Amazon.com (AMZN) will be in focus on Cyber Monday.
