Banco Santander (BME:SAN) has caught investor attention after a 15% share price gain over the past month, following a more moderate rise of about 3% over the past 3 months.

Set against a 15.0% 30 day share price return and a more muted 3.7% year to date move, Banco Santander’s very large 1 year total shareholder return of about 80.0% points to strong recent momentum from a longer term base.

With Banco Santander trading below some valuation estimates yet coming off a very strong 1 year total return, you need to ask whether there is still mispricing here or whether the market is already factoring in future growth.
Banco Santander’s most followed narrative points to a fair value of €11.90 per share, compared with the latest close of €10.63. This frames a modest valuation gap for investors to think about.
Ongoing transformation and cost reduction programs (ONE Transformation) are delivering structural operational leverage, with significant potential remaining as legacy systems are phased out. This supports a sustainable improvement in cost/income ratio and operating profits even in more muted economic environments.
Want to see what is sitting behind that value gap? The core narrative focuses on revenue, margins and an earnings multiple that may differ from some investor expectations.
The narrative uses a discount rate of 8.43% and ties fair value to expectations for higher euro revenue, wider profit margins and rising earnings over the coming years. It also assumes Banco Santander trades on a lower P/E in the future than today, while still supporting a higher share price, which is a key tension for you to weigh against your own expectations.
Result: Fair Value of €11.90 (UNDERVALUED)

However, this depends on loan quality in markets such as Brazil and on Santander actually delivering the planned technology and cost savings from its ONE Transformation program.
