Investors Cautious Ahead of Fed Minutes and Powell's Speech

Wall Street indexes opened slightly lower, with investors cautious ahead of the release of the Federal Reserve's meeting minutes and Jerome Powell's upcoming speech at Jackson Hole. The Dow, S&P 500, and Nasdaq all saw minor declines at the opening bell.

Wall Street's main indexes opened marginally lower on Tuesday, as investors refrained from risk taking in the lead-up to the release of minutes from the Federal Reserve's latest meet and Chair Jerome Powell's speech at Jackson Hole later this week.

The Dow Jones Industrial Average fell 22.0 points, or 0.05%, at the open to 40,874.52. The S&P 500 fell 5.4 points, or 0.10%, at the open to 5,602.88, while the Nasdaq Composite dropped 27.7 points, or 0.15%, to 17,849.087 at the opening bell.

Investor caution reflects the uncertainty surrounding potential policy shifts that may be revealed in the Fed minutes or Powell's address.
