Dec 20 (Reuters) - Wall Street's main indexes dropped at

the open on Friday on fears over high interest rates next year

although a cooler-than-expected inflation report for November

stymied losses.

The Dow Jones Industrial Average fell 46.0 points, or

0.11%, at the open to 42296.26. The S&P 500 fell 25.1

points, or 0.43%, to 5842​, while the Nasdaq Composite

dropped 182.7 points, or 0.94%, to 19190.042.
