Sept 14 (Reuters) - ‌The ​Nasdaq ​Composite and the S&P 500 ‌indexes opened lower on Monday, ⁠weighed down by a ‌selloff in key ‌AI stocks after top U.S. executives cited ​safety risks and called for a ⁠slowdown in artificial-intelligence development.

The S&P 500 ​fell 45.5 points, or 0.59%, at the ​open to 7,611.44, ‌while the Nasdaq Composite dropped 314.5 ⁠points, or 1.19%, to 26,018.502.

The Dow Jones ⁠Industrial Average rose 177.6 points, ​or 0.34%, at the open to 52,750.88. But it ‌quickly reversed course and was last ‌down 0.26%.
