U.S. stocks looked set to struggle for direction on Wednesday, with fresh North Korea worries appearing to weigh on sentiment.

Pyongyang overnight signaled its leader, Kim Jong Un, might pull out of next month’s summit with President Donald Trump if the U.S. insists on denuclearization for the isolated nation.

The equity market has scored significant gains so far this month, but it suffered a sizable drop on Tuesday, as the Dow halted an eight-session winning streak.

What are the main benchmarks doing?

Dow Jones Industrial Average futures inched lower by 13 points, or less than 0.1%, to 24,647, after a small early gain evaporated.

S&P 500 futures dipped by 0.75 point to 2,708.25, while those for the Nasdaq-100 edged down by 1.75 points to 6,888.75.

On Tuesday, the Dow , S&P and Nasdaq Composite all closed lower by 0.7% to 0.8%.

What are strategists saying?

Geopolitical risks are “rising again as North Korea pulls out of planned talks with South Korea and threatens to do the same with Donald Trump,” said Richard Perry, a Hantec Markets analyst, in a note.

“Kim Jong Un is apparently unhappy over the denuclearization program. As yet, there has only been a minor safe-haven move,” Perry added.

What are other markets doing?

Gold futures were roughly unchanged after earlier trading higher.

European stocks were struggling for direction, while Asian markets finished flat to lower.

Oil futures lost ground, and the ICE U.S. Dollar Index was gaining.

What’s driving markets?

The stock market seems to have turned a corner this month, overcoming some concerns about inflation, rising interest rates, trade fights and geopolitical tensions. The Dow is up 2.3% in May so far and roughly flat for the year, as of Tuesday’s close.

Even so, rising rates appear to be peeling some investors away from stocks. Tuesday’s selloff was blamed in part on the 10-year Treasury note’s yield rise to a seven-year high above 3%. The 10-year yield fell 1 basis point on Monday to trade at 3.066%.
