Mastercard: Remains A Buy Due To Its Dominant Duopoly Position

  • Mastercard remains a buy due to its dominant duopoly position, high margins, and consistent compounding returns above the S&P 500. The company's network scale creates a formidable moat, making new competition nearly impossible and ensuring long-term client loyalty. Value-added services, especially in security and analytics, are driving faster growth and deepening Mastercard's client relationships.
