American Express (AXP) Stock May Be 23% Cheap As ROE Stays Strong

Listen to the news

American Express stock has delivered a strong 112.0% gain over the past five years, yet current valuation checks send a more nuanced message, with the Excess Returns intrinsic value estimate suggesting the shares trade at a discount while market multiples look roughly in line with peers.

  • Over the past 5 years, American Express has returned 112.0%, which puts long term holders in a strong position despite more muted recent moves.
  • Future card spending and credit quality can support the valuation if they hold up, while any sustained hit to customer payment activity or higher loss rates may weigh on the earnings power investors are currently assuming.
  • The broader valuation workup is a mixed picture rather than a clear bargain or clear overvaluation, with the 4.0 value score set against an Excess Returns estimate that points to roughly a 22.7% discount to intrinsic value.

The issue now is whether American Express shares offer enough valuation upside relative to this intrinsic value estimate to appeal at current levels.

Is American Express Still Cheap on Excess Returns?

The Excess Returns model examines how much profit American Express can generate above its required cost of equity and then capitalises that stream. For American Express, the inputs point to a business that earns a wide gap between what shareholders require and what the firm is projected to produce.

Book value is set at $50.79 per share, with a stable book value estimate of $58.89 per share based on analyst forecasts. Against that asset base, stable EPS of $21.47 per share and an average return on equity of 36.46% compare with a cost of equity of $4.91 per share. That leaves an excess return of $16.56 per share in the model, which feeds into an intrinsic value estimate of about $416 per share.

With the stock price implying a 22.7% discount to that Excess Returns estimate, American Express appears undervalued on this framework.

On these inputs, American Express appears undervalued relative to the excess returns it is projected to earn on its equity base.

Where Does American Express Sit on Earnings?

The P/E ratio works well for American Express because earnings are a key anchor for how investors judge a mature payment and lending business. On this measure, the stock trades on about 19.2x earnings, which is roughly in line with the 20.2x average for its peer group in Consumer Finance.

The fair P/E multiple for American Express is estimated at 19.5x, only slightly above where the shares currently change hands. That small gap suggests the market is already factoring in the earnings profile, risk and scale implied by the model, rather than attaching a clear premium or discount compared with similar companies or the wider industry.

On the P/E test, American Express appears to be trading at roughly fair value rather than at a level that looks clearly cheap or expensive.

The Bottom Line

American Express screens as undervalued on the Excess Returns intrinsic value work, yet the P/E check suggests the share price already lines up closely with peers. That split comes from different emphases, with the intrinsic view leaning on the durability of excess profitability and the market view reflecting what investors are currently willing to pay for that earnings profile.
