AXP vs S&P 500: Which Stock to Watch

2026 Update: AXP vs. S&P 500 Performance Through October 26

Update prepared: October 27, 2026 Market-data cutoff: October 26, 2026, the latest completed U.S. market session Comparison period: December 31, 2025 close through October 26, 2026 close Latest financial cutoff: Third quarter ended September 30, 2026; results released October 23, 2026 Original-content cutoff: July 2025

Using the same start and end dates, AXP underperformed SPY, an exchange-traded fund used here as a tradable proxy for the S&P 500. The result reverses the broad conclusion in the original July 2025 draft, which had shown AXP ahead across its selected longer-term periods.

The distribution-inclusive estimate adds cash distributions whose ex-dividend dates occurred by the cutoff to the ending value. It does not assume reinvestment, taxes, fees, or fractional shares, so it is not identical to a fully reinvested total-return index.

American Express's operations remained profitable despite the share-price underperformance. Q3 2026 revenue net of interest expense increased 9% to $20.062 billion, billed business increased 8% to $454.0 billion, and adjusted EPS increased 13% to $4.68. The net write-off rate improved to 1.8%. Management expects approximately 10% revenue growth and adjusted EPS of $17.60–$17.90 for full-year 2026. AXP still carries single-company, consumer-credit, and travel-spending exposure, while SPY spreads exposure across hundreds of companies and sectors.

Original July 2025 Comparison: Historical Reference

In the original July 2025 comparison, American Express stock (NYSE: AXP) had delivered total returns that outpaced the S&P 500 over several measured multi-year periods, but that historical record does not settle the question every investor actually faces: does it justify concentrating capital in a single financial stock rather than simply owning the index? Every stock picker eventually confronts this tension: would the returns have been better with a low-cost S&P 500 index fund like SPY (SPDR S&P 500 ETF Trust) or VOO (Vanguard S&P 500 ETF)?

All performance figures in this analysis use total return, meaning price appreciation plus dividends reinvested, which is the correct metric for long-horizon comparison. The sections below cover AXP's performance track record, valuation, dividend profile, risk characteristics, and the investment thesis behind Berkshire Hathaway's decades-long conviction position, then deliver a clear framework for deciding whether AXP earns a place in your portfolio alongside or instead of index exposure.

About American Express (NYSE: AXP)

Company Overview and Key Metrics

American Express Company (NYSE: AXP) is a large-cap financial services company founded in 1850, headquartered in New York City, and a current component of the S&P 500 index. The company operates as an integrated payments network targeting affluent consumers and corporate clients through charge cards, credit cards, merchant services, and travel products. AXP is classified in the Financial Services sector under the GICS Diversified Financial Services sub-industry.

Investors who already hold SPY or VOO have indirect, diluted exposure to AXP. The stock represents approximately 0.7% of the S&P 500 index as of mid-2025, per Slickcharts.com, meaning the vast majority of AXP's moat-specific characteristics are diluted away in a broad index holding. The Financial sector as a whole represents roughly 13% of the S&P 500 by weight.

How American Express Makes Money: The Closed-Loop Advantage

American Express earns revenue through four primary channels: merchant discount fees charged to merchants who accept AXP cards, interest income on card balances extended to cardholders, annual fees on premium card products, and travel-related services. This revenue mix distinguishes American Express structurally from most payment companies.

The defining structural feature is AXP's closed-loop network. In a closed-loop network, a single company acts as both the card issuer and the payment network operator, capturing economics on both sides of every transaction. This contrasts with open-loop networks operated by Visa Inc. (NYSE: V) and Mastercard Incorporated (NYSE: MA), where the network operator and card issuer are separate entities. Chase or Citi issues a Visa-branded card while Visa processes the transaction and earns a fee from the network side only.

The closed-loop structure gives American Express two interlocking advantages. Richer transaction data from both the cardholder and merchant sides enables better fraud detection and targeted rewards. The ability to charge higher merchant discount rates (MDR, the fee AXP charges per transaction) is justified by the higher average spending of its cardholder base, specifically the affluent and high-income consumers AXP deliberately targets, who spend more per transaction, travel more frequently, and historically default at lower rates than mass-market cardholders. Products like the Platinum Card and the invitation-only Centurion Card (the "Black Card") reinforce this premium positioning. Like Visa, Mastercard (NYSE: MA) operates an open-loop network, earning transaction fees without carrying cardholder credit risk.

The trade-off is material. Because American Express extends credit to cardholders, it carries credit risk that Visa and Mastercard do not. That exposure is quantified in the risk section below, but it matters for understanding why AXP's business model behaves differently from a pure payment network during economic downturns.

AXP vs. S&P 500: Performance Comparison

The performance record between AXP and the S&P 500 spans periods of meaningful outperformance and stretches of underperformance, which is precisely why multi-period total return data tells a more complete story than any single-year snapshot.

Total Return Comparison: 1, 3, 5, and 10 Years

AXP vs. S&P 500 Total Return Comparison

All figures represent total return (price appreciation plus dividends reinvested). Source: historical third-party market data. As of July 2025. Figures are approximate.

American Express stock has beaten the S&P 500 on a total return basis across all four measured time horizons as of July 2025, delivering approximately 290% over 10 years compared to the index's roughly 255%. The outperformance is most pronounced over the recent 3-year period, where AXP's earnings recovery and premium card growth significantly exceeded broad market returns. The 10-year margin, while positive, is narrower because severe underperformance in 2019 and 2020 pulled the cumulative gap tighter. That 290% figure also excludes the additional per-share value creation from AXP's share buyback program, which has consistently reduced the share count over this period, compounding returns beyond what total return calculations capture alone. Investors comparing AXP to SPY over shorter windows may see different results depending on the start date.

Year-by-Year Annual Returns

The cumulative figures above reflect the aggregate result, but the year-by-year pattern shows whether AXP's outperformance has been consistent or concentrated in specific years.

AXP vs. S&P 500: Annual Total Return by Year

Source: historical third-party market data. As of July 2025. Figures approximate.

Alpha refers to the excess return a stock generates above its benchmark. AXP's alpha has been inconsistent across years: the stock significantly trailed the index in 2020 when travel and entertainment spending collapsed, and it modestly underperformed in 2019 and 2023. The strongest alpha years were 2024 and 2022, the latter a period when the S&P 500 fell sharply and AXP's premium cardholder spending proved more resilient than the broader market. This lumpy pattern is typical of single-stock positions: the long-term outperformance comes from a handful of strong years, not consistent annual margin expansion.

AXP Valuation: Is American Express Stock Overvalued or Undervalued?

Valuation context determines whether AXP's performance track record is available at a reasonable price or has been fully reflected in the current stock price.

P/E Ratio, EPS Growth, and Valuation Metrics vs. S&P 500

AXP Valuation Metrics vs. S&P 500 Average

Sources: historical third-party market data, July 2025. All figures approximate.

AXP's trailing P/E of approximately 21x as of July 2025 sits at a modest discount to the S&P 500's median trailing P/E of approximately 24x, in the original July 2025 market-data snapshot. AXP is growing earnings faster than the market and trades cheaper than the market. That combination is not the profile of a significantly overvalued stock. The 5-year adjusted EPS growth rate of approximately 18% annually is well above the S&P 500 average of roughly 10%, and some portion of that growth reflects buyback-driven accretion: AXP has consistently reduced its share count, which mechanically lifts EPS even before organic earnings expansion, so the quality of the growth is partly financial engineering rather than purely operational.

AXP's return on equity of approximately 35%, a Buffett-favored quality signal, reflects the efficiency with which the company generates profit from shareholder equity. High ROE in financial services is partly a function of leverage inherent to the business model, not purely organic earnings power, so it should not be read as a risk-free quality indicator in isolation. The forward P/E of approximately 18x, based on analyst consensus estimates in the original July 2025 market-data snapshot as of July 2025, suggests the market expects earnings growth to continue. At current levels, AXP does not appear to be pricing in a significant premium relative to its growth trajectory, though valuation is always a function of what comes next, not just what has occurred.

AXP Dividend Profile vs. S&P 500

AXP's dividend yield of approximately 1.1% as of July 2025, in the original July 2025 market-data snapshot, sits modestly below the S&P 500's average dividend yield of approximately 1.3%, per Multpl.com. The current yield alone understates the dividend case for long-term holders. AXP's 5-year compound annual dividend growth rate (CAGR) has been approximately 15%, in the original July 2025 market-data snapshot and American Express Investor Relations data, making it one of the stronger dividend growers among S&P 500 financial companies.

American Express's official dividend history shows that the quarterly common-stock dividend remained at $0.43 through 2020 rather than being suspended. The company later resumed dividend increases. Dividend payments are never guaranteed, but the original statement that AXP cut the quarterly payout to $0.10 in 2020 was incorrect and has been removed.

Beyond dividends, AXP's total capital return picture includes consistent share buybacks alongside growing dividend payments. Together, buybacks and dividends constitute total capital return to shareholders, and for AXP that total has historically exceeded what the yield figure alone would suggest. The investment case for AXP's dividend is primarily about growth trajectory over time. Investors seeking high current income will find 1.1% modest; those focused on long-term total return appreciate a dividend compounding at approximately 15% annually alongside a growing share price.

Why Warren Buffett Has Held American Express for Over 30 Years

Berkshire Hathaway (NYSE: BRK.A / BRK.B) first invested in American Express in the early 1990s when the company was under severe pressure from the salad oil scandal, a fraud scheme that left American Express exposed to hundreds of millions in losses and sent its stock sharply lower. Berkshire accumulated its position at distressed prices and has held continuously ever since, accumulating approximately 21% of AXP's outstanding shares as of Berkshire's most recent 13-F filing with the SEC (filed May 2025). That stake makes AXP one of Berkshire's three largest equity positions alongside Apple and its bank holdings.

The investment logic Buffett has articulated across Berkshire's annual letters rests on four specific characteristics, not simply faith in the brand name.

The first is brand moat with pricing power. American Express is one of the few financial brands that functions as a genuine status signal. Cardholder loyalty supports higher annual fees and stronger retention than mass-market card issuers can achieve, creating a durable revenue stream that competitors cannot easily replicate.

The second is premium franchise economics. AXP's cardholder base spends materially more per transaction than average credit card users and historically defaults at lower rates. That demographic concentration means American Express generates higher revenue per account and carries lower credit losses per dollar of receivables than issuers who serve the full consumer credit spectrum.

Third is capital efficiency. AXP generates returns on equity exceeding 30% without requiring heavy ongoing capital reinvestment in physical infrastructure. The business grows primarily by acquiring and retaining high-spending cardholders, a model Buffett has described as fitting the definition of a capital-light compounder. The approximately 35% ROE figure in the valuation table above illustrates why this characteristic appeals to value investors who weigh capital efficiency alongside earnings growth.

Fourth is the closed-loop network advantage. As explained in the business model section, AXP captures economics on both the cardholder and merchant sides of every transaction. This gives it richer data than open-loop network operators, justifying higher merchant discount rates and enabling more targeted rewards programs that reinforce cardholder loyalty.

One caveat matters for any investor evaluating AXP today: Berkshire's cost basis (the price Berkshire paid per share when it originally invested) is a small fraction of AXP's current market price. Buffett's returns are built on decades of compounding from a deeply discounted entry point. Investors buying AXP today are evaluating it at a fundamentally different valuation than Berkshire established its position. Berkshire's conviction endorses the quality of the business; it does not validate today's price as attractive for a new buyer.

AXP Risk Assessment: What You Are Taking On vs. the S&P 500

Three risk factors separate AXP from the index, and none of them appear in the return tables: single-stock concentration, credit cycle sensitivity from AXP's lending operations, and higher market sensitivity measured by beta above 1.0.

Beta and the Risk-Adjusted Question

Beta measures a stock's price sensitivity relative to the S&P 500. AXP's 5-year monthly beta of approximately 1.15 as of July 2025, in the original July 2025 market-data snapshot, means the stock has historically moved approximately 15% more than the index in both directions. In a strong bull market year, that amplification works in the investor's favor. In a sharp correction, it amplifies losses by the same proportion.

Raw return data does not capture this volatility cost. The Sharpe ratio measures return earned per unit of risk taken; a higher ratio indicates better risk-adjusted performance. Because AXP carries higher volatility than a diversified index, its raw return advantage must be evaluated on a risk-adjusted basis: higher returns that come with higher risk are not a free lunch. A well-diversified index like the S&P 500 tends to earn a competitive Sharpe ratio precisely because diversification reduces volatility without proportionally reducing returns. AXP as a single stock must generate meaningfully higher raw returns than the index to compensate for its greater volatility, and in years like 2020 it did not.

Concentration risk refers to the outsized portfolio volatility and potential for loss that comes from allocating significant capital to a single stock rather than spreading exposure across 500 companies. If an investor holds only AXP and the stock falls 30%, the portfolio falls 30%. That same 30% drop inside an S&P 500 index fund produces less than a one-percentage-point portfolio impact given AXP's sub-1% weighting. The opportunity cost dimension matters too: if AXP underperforms the index over a 5- or 10-year period, the investor has sacrificed the market return they could have captured simply by holding SPY or VOO. That foregone return is the concrete downside of single-stock concentration over a long horizon.

The practical solution is position sizing, not avoidance. An investor who believes in AXP's long-term thesis may treat it as a smaller satellite position beside a diversified core rather than replacing index exposure entirely. The appropriate size depends on the investor's objectives, risk capacity, and total portfolio; there is no universal allocation range.

AXP in Recessions and Market Downturns

During the 2008 to 2009 financial crisis, AXP fell approximately 75% peak-to-trough, compared to the S&P 500's decline of approximately 57% over the same period, according to historical data from Macrotrends.net. That roughly 18-percentage-point gap in drawdown reflects AXP's direct exposure to consumer credit losses: as unemployment rose and consumer spending contracted, AXP's loan delinquencies climbed and its profitability compressed sharply. Being a premium card issuer offered some protection relative to subprime lenders, but it did not protect the stock from systemic financial stress.

During the COVID-19 crash of February through March 2020, AXP fell approximately 54% from its peak before recovering sharply through 2021 and into 2022. The specific damage came from travel and entertainment spending collapsing within weeks, since that category is a disproportionate share of AXP's cardholder spending mix. Investors who held through 2020 participated in significant gains in 2021 as travel normalized.

The 2022 rate hike cycle produced a different outcome. AXP navigated rising interest rates with strong earnings, as higher rates supported net interest income on card balances and AXP's premium customer base continued spending through the inflationary environment. AXP's -1% total return that year significantly outperformed the S&P 500's -18% decline.

AXP's net write-off rate, the percentage of outstanding card loans written off as uncollectable, is a key metric investors should monitor. As of Q1 2025, per American Express Investor Relations quarterly earnings disclosures, AXP's net write-off rate was approximately 2.1%, modestly above pre-pandemic norms of 1.6% to 1.9% but well below crisis-level peaks. Rising write-off rates signal credit quality deterioration and can compress AXP's profitability before that pressure shows up in price performance. Investors in AXP should track this figure quarterly as a forward-looking indicator of credit cycle stress.

Updated AXP vs. S&P 500 Verdict and Investment Framework

The 2026 comparison changes the short-term conclusion. From December 31, 2025 through October 26, 2026, AXP lost 14.84% on price while SPY gained 12.24%. After adding cash distributions with ex-dates through the cutoff, AXP's estimated return was -13.85% versus +13.06% for SPY. The longer-term July 2025 tables remain historical context, but they do not support a claim that AXP consistently beats the index across every period.

For investors asking whether AXP adds value beyond a financial sector ETF: yes, meaningfully. XLF, the Financial Select Sector SPDR ETF, holds banks and insurance companies whose risk and return profiles differ sharply from AXP's premium network model. AXP-specific alpha requires owning AXP directly.

At the October 26, 2026 cutoff, AXP's business fundamentals remained profitable and management raised full-year adjusted EPS guidance to $17.60–$17.90. That operating strength did not prevent 2026 share-price underperformance. Investors should evaluate company fundamentals separately from the relative return delivered over a specific measurement window.

AXP vs. S&P 500: Decision Framework by Investor Profile

The AXP thesis should be monitored against changes in credit quality (track the net write-off rate quarterly), competitive dynamics in the premium card space, and valuation expansion that might erode the current discount to the broader market.

Frequently Asked Questions: AXP vs. S&P 500

Has American Express stock beaten the S&P 500?

Not in the 2026 period measured here. From December 31, 2025 through October 26, 2026, AXP returned approximately -14.84% on price and -13.85% after adding eligible cash distributions, while SPY returned approximately +12.24% on price and +13.06% after distributions. AXP did outperform across the separate historical periods measured in the original July 2025 snapshot, which shows why every comparison must use identical start dates, end dates, and dividend treatment.

Is AXP a good long-term investment?

AXP has demonstrated viable long-term investment characteristics for investors comfortable with single-stock concentration risk, supported by multi-decade outperformance, Berkshire Hathaway's conviction position, consistent EPS and dividend growth, and a durable closed-loop competitive moat. For investors asking whether AXP is a good stock to buy today: the decision depends on valuation, objectives, risk capacity, and the role of diversified holdings in the portfolio. The concentration risk caveat is material: a single-stock holding in AXP exposes the portfolio to specific drawdown risk that a diversified index fund does not carry, and past performance does not guarantee future results.

Why does Warren Buffett own American Express stock?

Berkshire Hathaway has held American Express since the early 1990s primarily because of its closed-loop payment network, its premium cardholder franchise that spends more and defaults less than mass-market issuers, and its track record of generating high returns on equity without requiring heavy capital reinvestment. Berkshire currently owns approximately 21% of AXP's outstanding shares, one of its three largest equity positions, per the May 2025 13-F filing. Investors buying AXP today are not buying at Berkshire's cost basis, which is a fraction of the current market price.

What is AXP's dividend yield, and does American Express pay a good dividend?

AXP's dividend yield is approximately 1.1% as of July 2025, in the original July 2025 market-data snapshot, compared to the S&P 500's average dividend yield of approximately 1.3%, per Multpl.com. The yield is modest, but AXP's 5-year annual dividend growth rate has been approximately 15%, making it a stronger compounder than the raw yield implies. American Express maintained its $0.43 quarterly common-stock dividend through 2020 and later resumed dividend increases. The latest declared quarterly rate at the 2026 cutoff was $0.95, although future dividends remain subject to board approval.

Is AXP stock overvalued compared to the market?

As of July 2025, AXP's trailing P/E of approximately 21x compares to the S&P 500's median trailing P/E of approximately 24x, in the original July 2025 market-data snapshot, placing AXP at a modest discount to the broader market. Given AXP's 5-year EPS growth rate of approximately 18% versus the S&P 500 average of approximately 10%, the discount appears defensible rather than a signal of deteriorating fundamentals. AXP does not appear significantly overvalued at current levels, though no single metric determines fair value and conditions change continuously.

What percentage of the S&P 500 is American Express?

S&P 500 index investors hold roughly 0.7% of a position in AXP's performance through SPY or VOO as of mid-2025, according to Slickcharts.com. That diluted weight means index ownership provides some indirect AXP exposure, but investors who are specifically bullish on American Express's closed-loop moat need to own AXP directly to express that thesis at a meaningful scale.

Should I invest in AXP or an S&P 500 index fund?

An S&P 500 index fund such as SPY or VOO offers broad market exposure, while AXP adds single-company concentration and credit-cycle risk. For investors who believe in AXP's closed-loop competitive moat and are comfortable with single-stock concentration, AXP as a satellite position alongside core index holdings is a considered alternative. The two approaches are not mutually exclusive. Many investors hold both: a core index position providing market diversification, and a satellite AXP allocation sized to reflect conviction without excessive concentration risk. The disclaimer at the end of this article applies to all of the above.

How does American Express compare to Visa and Mastercard?

American Express operates a closed-loop network, acting as both the card issuer and the payment network operator, while Visa (NYSE: V) and Mastercard (NYSE: MA) operate open-loop networks where third-party banks issue the cards and the network companies earn transaction fees without carrying cardholder credit risk. This means AXP carries more credit risk than Visa or Mastercard but also maintains richer transaction data, charges higher merchant discount rates justified by its affluent cardholders, and holds a direct cardholder relationship that the open-loop networks do not. AXP targets the premium and affluent consumer segment; Visa and Mastercard serve the full consumer market spectrum. Investors choosing between payment sector stocks should weigh AXP's higher-return, higher-risk profile against Visa and Mastercard's cleaner network economics and recession resilience.
