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

1. -- Stocks Trade Lower as Shutdown Rally Fizzles

U.S. stock futures declined on Monday, Jan. 28, and global stocks drifted lower as last week's late-hour rally on Wall Street, sparked by a surprise concession from Donald Trump to end the 35-day government shutdown, fizzled as markets shifted their focus to a series of major event risks and blue chip corporate earnings in the day ahead.

Investor optimism linked to Trump's decision to sign a bill that funds the government until Feb. 15, faded in the wake of comments he made during an interview with The Wall Street Journal, as well as on social media, that he may double-down on his demand for $5.7 billion in border wall funding when talks between lawmakers resume this week.

"I personally think it's less than 50-50, but you have a lot of very good people on that board," Trump told the Journal when asked about the chances for a longer-term government funding bill, adding that another shutdown next month was "certainly an option."

Investors also were in a cautious mood following data from China that showed industrial profits for December fell by a more-than-expected 1.9%, the second monthly decline and a figure that brings the 2018 tally to 10.3%, around half the pace of 2017 and further cementing concerns of a slowdown in the world's second-biggest economy.

Contracts tied to the Dow Jones Industrial Average fell 100 points, futures for the S&P 500 slipped 11.50 points, and Nasdaq futures were down 32.25 points. 

The economic calendar in the U.S. Monday includes the Chicago Fed National Activity Index for December at 8:30 a.m. ET, and the Dallas Fed Manufacturing Survey for January at 10:30 a.m.
