American Express reported strong third-quarter earnings, with profit rising to $2.51 billion or $3.49 per share, surpassing analysts' expectations of $3.28. Despite missing revenue predictions slightly at $16.64 billion, the company experienced an 8% increase from the previous year, driven by robust cardholder spending and increased card fee revenue. American Express's provisions for credit losses rose to $1.4 billion, reflecting increased financial caution amidst economic uncertainty. The company's focus on affluent customers has helped shield it from economic downturns, although analysts warn of limited future growth potential due to its high stock price. American Express also raised its full-year earnings outlook to between $13.75 and $14.05 per share. Shares have risen significantly, up 53% year-to-date, indicating strong investor confidence.
