July 13 (Reuters) - The S&P 500 and the Nasdaq opened lower

on Monday, as a fresh escalation between the U.S. and Iran in

the Gulf pushed oil prices higher and unsettled investors, while

chip stocks also came under pressure.

The Dow Jones Industrial Average rose 39.5 points, or

0.08%, at the open to 52676.53. The S&P 500 fell 27.9

points, or 0.37%, at the open to 7547.53​, while the Nasdaq

Composite dropped 193.3 points, or 0.74%, to 26088.313

at the opening bell.
