The Dow booked its fourth gain in a row on Monday but the broader market notched slight losses as investors looked ahead to European Central Bank and the Federal Reserve monetary policy moves, with both central banks expected to reveal easier-money initiatives in coming days amid mixed global economic data and an uncertain future for U.S.-China trade relations.

The Dow Jones Industrial Average DJIA, +1.33% rose 38.05 points, or 0.1%, to 26,835.51, recording its fourth straight gain, matching a similar win streak ended July 15. Meanwhile, the S&P 500 index SPX, +1.59% lost less than a point, or 0.01%, to 2,978.43, and the Nasdaq Composite Index COMP, +2.26% shed 15.64 points, or 0.2%, to 8,087.44.

At session highs, the Dow rose 103.37 points, or 0.4%, the S&P was up 9.36 points, also 0.3% and the Nasdaq added 48.2 points, or 0.6%.

What’s driving the market?

U.S. stocks saw choppy trade Monday as investors weighed Beijing and Washington’s plan to renew talks next month, and as investors anticipated stimulus from global central banks.

“There’s a belief that there will be a meeting [between the U.S. and China] sometime in October, though we don’t have a date or agenda yet,” Randy Frederick, vice president of trading and derivatives at the Schwab Center for Financial Research told MarketWatch.

“It’s a fairly thin proposition,” Frederick said, adding that given the apparent differences in negotiating positions between the U.S. and China, “I’m having a difficult time imagining a real trade agreement.”

He said that while hopes for further monetary stimulus may be boosting confidence among some investors, but “the fact that we’re this close to an all time high puts us in a dangerous situation and makes the market vulnerable to a pullback.”

The European Central Bank is widely expected to deliver a further rate cut, pushing its deposit rate further into negative territory, when policy makers meet Thursday. The ECB may also move to restart a bond-buying program it ended in December as it responds to a slowing economy and stubbornly below-target inflation.

Expectations for more stimulus were high even as German exports unexpectedly rose in July, following a run of downbeat economic data out of Europe’s largest economy.

In addition, Fed policy makers meet next week, with recent data, including last Friday’s weaker-than-expected jobs report, seen underlining expectations it will move to cut its key lending rate.

Last week’s renewed trade optimism appeared to spill over to Monday, following a report over the weekend that Chinese officials had offered to buy agricultural goods in exchange for concessions related to Huawei Technologies Co. or a delay of tariffs set to go into effect in October and December.

U.S. Treasury Secretary Steven Mnuchin said Monday on Fox Business Network that China’s decision to meet for talks next month is a sign of “good faith,’ but that the administration is willing to continue with its tariff policy unless a good deal for U.S. companies and workers can be struck.

On the economic data front, a report on consumer borrowing showed a pickup in July, with borrowing rising at the fastest rate in almost two years, according to Fed data released Monday. Total consumer credit increased $23.3 billion. That’s an annual growth rate of 6.8%, up from a 4.1% rate in the prior month, representing the fastest pace since November 2017.

Later this week, investors will get a look at the August producer-price index on Wednesday, followed by the consumer-price index on Thursday and August retail sales data on Friday.
