Corporate Earnings and Diplomatic Meetings Drive September Market Volatility

Wall Street is preparing for a volatile week starting September 21, 2026, following a quarter-point interest rate hike by the Federal Reserve System that triggered a 1.7% drop in the Dow Jones Industrial Average. Market participants are tracking a combination of geopolitical events and corporate disclosures to gauge economic direction.

Donald Trump is scheduled to meet with Chinese President Xi Jinping in Washington, D.C., an encounter expected to influence market stability. In the technology sector, Meta Platforms Incorporated will host its Connect product unveiling, while Okta CEO Todd McKinnon will lead an analyst meeting on Wednesday to discuss identity-security technology for AI agents.

Corporate earnings and investor days are scheduled throughout the week. KB Home reports on Tuesday, followed by Cintas, Paychex, and General Mills on Wednesday. Darden Restaurants and Costco are expected to report on Thursday, while McDonald's and AutoZone also have anticipated updates. In the pharmaceutical sector, Mirum Pharmaceuticals is awaiting a U.S. Food and Drug Administration decision on the approval of zilurgisertib, a result that could significantly impact the company's share value.
