Approach 1: American Express Excess Returns Analysis

The Excess Returns model looks at how much value a company creates over and above the return that equity investors require. It starts with what shareholders have invested and then compares the return on that equity to the company’s estimated cost of equity.

For American Express, the model uses a Book Value of $49.85 per share and a Stable Book Value of $58.93 per share, based on weighted future book value estimates from 8 analysts. On the earnings side, it assumes Stable EPS of $21.19 per share, guided by return on equity estimates from 13 analysts, and an Average Return on Equity of 35.96%. The implied Cost of Equity is $4.87 per share, which leads to an Excess Return of $16.32 per share.

Aggregating these excess returns and discounting them back gives an intrinsic value estimate of about $404.30 per share. Compared with the current share price of around $316, the model implies an intrinsic discount of 21.7%. This indicates that the stock is trading below this valuation estimate.

Result: UNDERVALUED

Our Excess Returns analysis suggests American Express is undervalued by 21.7%. Track this in your watchlist or portfolio, or discover 46 more high quality undervalued stocks.

Approach 2: American Express Price vs Earnings

The P/E ratio is a common way to think about value for profitable companies because it links what you pay per share to the earnings that support that price. In simple terms, a higher P/E usually reflects higher growth expectations or lower perceived risk, while a lower P/E can reflect more modest growth expectations or higher perceived risk.

American Express currently trades on a P/E of 19.48x. That is well above the Consumer Finance industry average P/E of 9.06x, and slightly above the peer group average of 19.21x. On the surface this suggests the stock is priced at a premium to the broader industry and is roughly in line with closer peers.

Simply Wall St’s Fair Ratio for American Express is 18.76x. This is a proprietary estimate of what the P/E could be given factors such as earnings growth, industry, profit margins, market cap and risk. Because it is tailored to the company, it can be more informative than a simple comparison with industry or peer averages. With the actual P/E at 19.48x versus a Fair Ratio of 18.76x, the stock screens as slightly overvalued on this metric.

Result: OVERVALUED
