NEW YORK, July 1 (Reuters) - The major U.S. stock indexes clung to modest increases on Friday, helped by encouraging U.S. manufacturing data, putting them on pace for a fourth straight day of gains.
The S&P 500 was on track for its best week since November, staging a strong rebound after its worst two-day decline in 10 months after Britain's shock vote last week to leave the European Union. The indexes have erased almost all their losses stemming from the "Brexit" vote.
"Clearly, people have assessed that either, one, it's not a big deal, or, two, it's not going to happen at all, and they're positioning according to those views," said Walter Todd, chief investment officer at Greenwood Capital in Greenwood, South Carolina.
The Dow Jones industrial average was up 18.97 points, or 0.11 percent, at 17,948.96, the S&P 500 had gained 2.98 points, or 0.14 percent, at 2,101.84 and the Nasdaq Composite added 14.28 points, or 0.29 percent, at 4,856.95. Continuación...
