Approach 1: American Express Excess Returns Analysis

The Excess Returns model looks at how much profit a company is expected to earn above the return that shareholders require, then adds that stream of extra value to its book value per share.

For American Express, the model starts with a Book Value of $47.05 per share and a Stable EPS of $20.43 per share, based on weighted future Return on Equity estimates from 9 analysts. The Average Return on Equity is 37.18%, while the Cost of Equity is $4.58 per share, which implies an Excess Return of $15.85 per share. In other words, the company is modeled to earn more on its equity base than the return investors are assumed to require.

The Stable Book Value used in the model is $54.94 per share, sourced from weighted future Book Value estimates from 6 analysts. Combining this book value with the projected excess returns produces an intrinsic value estimate of about $367.61 per share.

Compared with the recent share price of about $352.17, the Excess Returns model points to roughly a 4.2% discount, which is quite small.

Result: ABOUT RIGHT

American Express is fairly valued according to our Excess Returns, but this can change at a moment's notice. Track the value in your watchlist or portfolio and be alerted on when to act.

Approach 2: American Express Price vs Earnings

For a profitable company like American Express, the P/E ratio is a useful way to see how much you are paying for each dollar of earnings. It links directly to what the business is currently earning, which is often easier to relate to than cash flow or book value models.

What counts as a "fair" P/E usually reflects the trade off between expected growth and risk. Higher growth or lower perceived risk can support a higher multiple, while slower growth or higher risk tends to justify a lower one.

American Express currently trades on a P/E of 23.30x. That is above the Consumer Finance industry average P/E of 8.69x and slightly above the peer group average of 22.58x. Simply Wall St also calculates a proprietary Fair Ratio of 20.32x, which is the P/E level it would expect given factors such as earnings growth, profit margins, industry, market cap and specific risks.

This Fair Ratio can be more informative than a simple peer or industry comparison because it adjusts for company specific characteristics rather than assuming all Consumer Finance stocks should trade at the same multiple.

With the current P/E of 23.30x sitting above the Fair Ratio of 20.32x, this approach points to American Express appearing overvalued on earnings.

Result: OVERVALUED
