March 28 (Reuters) - Wall Street's main indexes opened

lower on Friday as data showed underlying price pressures rose

more than expected last month and fueled concerns that the Trump

administration's tariff policies could further stoke inflation.

The Dow Jones Industrial Average fell 53.9 points, or

0.13%, at the open to 42,245.82. The S&P 500 fell 14.1

points, or 0.25%, at the open to 5,679.2​, while the Nasdaq

Composite dropped 81.9 points, or 0.46%, to 17,722.087

at the opening bell.
