American Express Stock Edges Lower Amid Valuation Concerns

American Express stock closed at $320.71 on the New York Stock Exchange on September 10, 2026, down 0.34 percent from the previous session.

The company's long-standing link to Berkshire Hathaway remains a significant factor in its valuation, with roughly 82 percent of Berkshire's portfolio concentrated in just 10 large positions, including American Express as one of its core financial holdings.

Analysts see the stock as reasonably valued with room for appreciation, with an average 12-month price target of $373.32 and a consensus rating of 'Moderate Buy' from the analyst community.
