U.S. stock futures on Tuesday pointed to an upbeat open on Wall Street, with the Dow on track to break a four-session losing run.

Six Dow components reported earnings, including Coca-Cola and United Technologies, but the bulk of the gains were coming from shares that either already reported or will report soon.

What are markets doing?

Futures for the Dow Jones Industrial Average jumped 154 points, or 0.6%, to 24,566, while those for the S&P 500 index added 15.45 points, or 0.6%, to 2,687. Futures for the Nasdaq-100 index climbed 36.75 points, or 0.5%, to 6,703.50.

The indicated gains come after a mostly weak session on Monday, when the Dow lost less than 0.1%, the Nasdaq Composite Index fell 0.3% and the S&P 500 index closed virtually unchanged.

What is driving the market?

Stocks have been whipped around by rising U.S. bond yields recently, as the 10-year rate looked like it was about to break above the psychologically important 3% handle. Higher bond yields tend to weigh on stocks because they push up borrowing costs for corporate.

Yields initially pulled back on Tuesday, but then turned higher to trade around 2.989%, up around 2 basis points. Yields and debt prices move in opposite directions.

Earnings were also a major focus on Tuesday, with a deluge of high profile companies reporting results before the open. The season has so far been strong, and more than 80% of the S&P 500 companies reporting so far have beaten profit forecasts. That compares with the fourth quarter of 2017, when around 73% of S&P companies topped estimates, according to FactSet data.

What are strategists saying?

U.S. 10-year yields will “be monitored closely this week, as they were less than 0.3 basis points from breaking the 3% benchmark yesterday,” said Hussein Sayed, chief market strategist at FXTM, in a note.

“The 3% by itself is just a psychological level and not a significant threat, but if a break above leads to further selling in Treasury bonds, that’s going to be a serious warning signal for equity bulls. With a current world running on A.I and algorithms, a selloff may look ugly,” he added.
