Approach 1: American Express Excess Returns Analysis

The Excess Returns model looks at how much profit a company can generate above the return that shareholders require, then capitalizes those surplus returns into a value per share. It is built around profitability on equity rather than cash flows.

For American Express, the model uses a Book Value of $49.85 per share and a Stable EPS of $21.18 per share, based on weighted future Return on Equity estimates from 12 analysts. The implied Average Return on Equity is 36.18%, while the Cost of Equity is $4.84 per share. That leaves an Excess Return of $16.34 per share, which is the core input to this approach.

The Stable Book Value is set at $58.55 per share, based on estimates from 8 analysts. Combining these inputs, the Excess Returns model produces an intrinsic value of about $404.41 per share. Compared with the recent share price of $315.95, this points to an implied discount of 21.9%, which suggests the stock is undervalued on this framework.

Result: UNDERVALUED

Our Excess Returns analysis suggests American Express is undervalued by 21.9%. Track this in your watchlist or portfolio, or discover 51 more high quality undervalued stocks.

Approach 2: American Express Price vs Earnings

The P/E ratio is a useful way to value profitable companies because it links what you pay for each share with the earnings that company is currently generating. For you as an investor, it is a quick way to see how many dollars of price the market is asking for each dollar of earnings.

What counts as a “normal” P/E depends on how fast earnings are expected to grow and how risky those earnings are. Higher expected growth or lower perceived risk can justify a higher P/E, while lower growth or higher risk usually argue for a lower multiple.

American Express trades on a P/E of 19.44x. That is higher than the Consumer Finance industry average of 9.80x, and slightly above the peer average of 19.20x. Simply Wall St’s Fair Ratio for American Express is 18.90x. This Fair Ratio is a proprietary estimate of what a reasonable P/E could be for this specific company, based on factors like its earnings growth profile, industry, profit margins, market cap and risk characteristics. Because it is tailored to the company, it can be more informative than a simple comparison with broad industry or peer averages.

Compared with the Fair Ratio of 18.90x, the current P/E of 19.44x points to American Express looking overvalued on this metric.

Result: OVERVALUED
