American Express Plunges 7.2% as $2.28B Volume Surges to 40th-Most-Traded

Market Snapshot

American Express (AXP) closed on February 23, 2026, with a steep decline of 7.20%, marking its worst single-day performance in recent months. The stock’s trading volume surged to $2.28 billion, a 141.74% increase from the previous day, ranking it 40th in terms of activity across the market. This sharp drop occurred amid broader market volatility, as major indices like the S&P 500 and Dow Jones Industrial Average also fell by over 1%. The surge in volume suggests heightened investor concern or speculative activity, though the company’s fundamentals—such as its recent earnings or operational updates—were not explicitly cited in the provided data as direct causes for the decline.

Key Drivers

The provided news articles focus on American International Group (AIG), not American Express, and contain no direct references to AXP’s performance. However, indirect market dynamics and sector-wide trends inferred from the AIG-related content may offer context for AXP’s drop.

First, the broader financial sector faced headwinds, as evidenced by AIG’s mixed financial indicators and declining net premiums. While AIG’s Q4 2025 results showed a net income of $735 million, analysts highlighted challenges such as reduced premium income and elevated underwriting risks. These trends could have spilled over to other financial stocks, including AXP, as investors reassessed the sector’s resilience amid macroeconomic uncertainties like inflation and interest rate volatility.

Second, AIG’s stock price closed at $79.98, down 0.57% for the day, despite a recent dividend announcement of $0.45 per share. While AIG’s decline was relatively modest compared to AXP’s 7.20% drop, the broader market’s risk-off sentiment—reflected in the S&P 500’s 1.04% decline—suggests that sector-specific concerns may have been amplified by macroeconomic fears. AXP, as a financial services provider, could have been caught in this tide of caution, particularly if investors perceived similar vulnerabilities in credit card operations or corporate lending.

Third, the news articles emphasized AIG’s cautious optimism about future earnings growth and improved underwriting discipline. This tempered outlook, coupled with AIG’s forward dividend yield of 2.24%, contrasts with AXP’s current valuation metrics. While AXP’s price-to-earnings (P/E) ratio and earnings per share (EPS) were not explicitly mentioned, the market’s reaction to AIG’s conservative guidance may have signaled a broader shift toward risk aversion. AXP’s steep decline could reflect investor concerns about its exposure to high-interest-rate environments or potential credit risk in its credit card portfolio.

Finally, the absence of AXP-specific news in the provided data underscores the role of external factors. For instance, AIG’s stock is part of the S&P 500, and its performance may have been influenced by index-wide movements. AXP’s significant drop, therefore, could be attributed to a combination of sector-wide anxiety and a lack of positive catalysts, such as strong earnings or strategic updates. Analysts’ mixed recommendations for AIG—ranging from “Strong Buy” to “Hold”—also highlight the sector’s fragmented outlook, which may have contributed to AXP’s underperformance.

In summary, while the provided news articles do not directly address AXP’s performance, the broader financial sector’s challenges, macroeconomic headwinds, and market sentiment toward insurance and financial services firms like AIG suggest that AXP’s decline was part of a larger trend. Investors appeared to prioritize caution over optimism, leading to heightened volatility in the sector.
