UBS has reaffirmed its "Buy" rating for Banco Santander SA, raising the target price to €6.30, citing confidence in the bank's stable earnings and projected growth. Despite a recent share price drop, the bank's valuation remains attractive, trading at low earnings multiples compared to industry averages. Additionally, Santander plans to launch a full-service digital bank in the U.S. by 2025, aiming to enhance its market presence and support significant auto lending activity.
