Approach 1: American Express Excess Returns Analysis

The Excess Returns model evaluates how much profit a company is expected to generate above the return that shareholders require, based on its equity cost, and then capitalizes those excess profits into an intrinsic value per share.

For American Express, the model starts with a Book Value of $49.85 per share and a Stable EPS of $21.24 per share, based on weighted future Return on Equity estimates from 12 analysts. The Average Return on Equity is 36.04%, compared with a Cost of Equity of $4.84 per share. That gap produces an Excess Return of $16.40 per share on the current equity base.

The analysis also uses a Stable Book Value estimate of $58.93 per share, sourced from weighted future Book Value estimates from 8 analysts, to illustrate how these excess returns may compound over time as the equity base grows.

Combining these inputs, the Excess Returns model produces an intrinsic value of about $409.55 per share. Compared with the recent share price of $309.61, this calculation implies the stock is 24.4% undervalued within the framework of this model.

Result: UNDERVALUED (per model output)

Our Excess Returns analysis suggests American Express is undervalued by 24.4%. Track this in your watchlist or portfolio, or discover 46 more high quality undervalued stocks.

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 ties the share price directly to current earnings, which is what ultimately supports long term returns.

What counts as a “normal” or “fair” P/E depends on how the market views a company’s growth prospects and risk. Higher expected growth and lower perceived risk usually justify a higher multiple, while slower growth and higher risk point to a lower one.

American Express currently trades on a P/E of 19.05x. That is close to the peer average of 18.97x and above the broader Consumer Finance industry average of 9.33x. Simply Wall St’s Fair Ratio for American Express is 18.79x. This Fair Ratio is a proprietary estimate of the P/E that could be reasonable given the company’s earnings growth profile, industry, profit margins, market cap and risk factors.

Compared with simple peer or industry comparisons, the Fair Ratio aims to be more tailored because it blends those company specific drivers instead of treating all Consumer Finance stocks as alike. With the current P/E of 19.05x sitting slightly above the Fair Ratio of 18.79x, the stock screens as modestly overvalued on this metric.

Result: OVERVALUED
