NEW YORK—U.S. stock futures are rising for a fourth consecutive day, capping the biggest rally for S&P 500 index since January, thanks to a healthy dose of favorable economic news.

The S&P is now up 13 percent for the year, which makes it the best first half for the index since 2008.

Dow Jones industrial futures are up 23 points to 14,959. S&P futures have added 2.6 points to 1,609.20. Nasdaq futures are up 3.5 points to 2,903.

U.S. futures followed Asian markets higher Friday after a closely watched consumer price index in Japan, which has battled deflation for years, stopped falling for the first time in seven months.

Also on Friday, the Institute for Supply Management posts its gauge of business activity for June from Chicago.
