Jan 27 (Reuters) - Wall Street's main indexes opened

lower on Monday, as the surging popularity of a low-cost Chinese

artificial intelligence model sparked a selloff in chipmaker

Nvidia and other companies that stand to benefit from

investments into the technology.

The Dow Jones Industrial Average fell 275.4 points,

or 0.62%, at the open to 44,148.84. The S&P 500 fell

132.2 points, or 2.17%, at the open to 5,969.04​, while the

Nasdaq Composite dropped 720.3 points, or 3.61%, to

19,234.042 at the opening bell.
