Most Popular Narrative: 2.6% Overvalued

Despite the buzz around American Express, the narrative consensus puts its fair value slightly below the current market price. This raises questions about the stock’s upward potential at these levels.

The company's ongoing focus on premium cardmembers and product refreshes, especially the upcoming U.S. Platinum Card relaunch, positions American Express to benefit from consumers' growing demand for personalized experiences and value-added rewards. This trend is likely to boost net card fee growth and retention, which supports long-term revenue and fee income expansion.
