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 equity investors typically require, then capitalizes those extra profits into an intrinsic value per share.

For American Express, the model uses a Book Value of $49.85 per share and a Stable EPS of $21.19 per share, based on weighted future Return on Equity estimates from 12 analysts. The Average Return on Equity is 36.14%, while the Cost of Equity is $4.88 per share, implying an Excess Return of $16.32 per share. Stable Book Value is put at $58.64 per share, using estimates from 8 analysts.

These figures feed into the Excess Returns framework to arrive at an intrinsic value of about $391.39 per share. With the current share price around $318.84, this implies the stock trades at roughly an 18.5% discount to that estimate. On this model, American Express appears undervalued.

Result: UNDERVALUED

Approach 2: American Express Price vs Earnings

P/E is a common way to value established, profitable companies because it links what you pay for each share directly to the earnings that business is currently generating.

What counts as a “normal” P/E depends on how the market views a company’s earnings growth potential and risk profile. Higher expected growth or lower perceived risk usually justify a higher P/E, while slower growth or higher risk tend to pull it down.

American Express currently trades on a P/E of 19.62x. That is close to the Consumer Finance industry average of 9.33x and the peer group average of 20.04x. Simply Wall St’s Fair Ratio for American Express is 18.14x. This Fair Ratio is a proprietary estimate of what the P/E “should” be, given factors such as earnings growth, profit margins, industry, market cap and key risks.

Compared with simple peer or industry comparisons, the Fair Ratio aims to give a more tailored view because it adjusts for the specific characteristics of the business rather than using broad group averages.

Since the current P/E of 19.62x is modestly higher than the Fair Ratio of 18.14x, the shares look slightly expensive on this metric.

Result: OVERVALUED
