Banco Santander, S.A. (SAN) stock: Winston Score and insider trades

Banco Santander is one of the largest banks in the world, headquartered in Spain. It offers everyday banking services like checking accounts, savings accounts, loans, mortgages, and credit cards to both regular people and businesses. It also provides services to large corporations and offers investment and wealth management products. Santander makes money primarily by charging interest on loans and collecting fees for banking services. It operates across more than 10 countries, with its biggest markets being Spain, Brazil, the United Kingdom, Mexico, and the United States, serving roughly 160 million customers globally. Its scale across Europe and Latin America gives it a broad geographic diversification that smaller banks cannot easily match. The key growth driver is continued expansion in fast-growing Latin American markets, particularly Brazil and Mexico, though the bank faces ongoing risks from currency fluctuations in those regions and from rising loan defaults if economic conditions weaken.
