Wall Street's main indexes opened unchanged on Monday as investors remained on the fence ahead of key inflation data later this week, while heavyweight technology shares largely shrugged off a deal by the world's richest nations on a global minimum corporate tax.

The Dow Jones Industrial Average rose 9.8 points, or 0.03%, at the open to 34766.2. The S&P 500 fell 0.6 points, or 0.01%, at the open to 4229.34, while the Nasdaq Composite dropped 11.7 points, or 0.08%, to 13802.82 at the opening bell.
