Goldman Sachs vs. Interactive Brokers: Which Financial Stock Is a Better Buy in 2026?

Goldman Sachs and Interactive Brokers represent two different approaches to financial services. Goldman Sachs dominates institutional finance with $3.6 trillion in assets under supervision and a 29.5% net margin, but carries significant debt (4.9x debt-to-equity) and negative free cash flow. Interactive Brokers operates a highly automated platform serving 5 million accounts with 70% net margin, zero debt, and $15.7 billion in free cash flow. The choice depends on investment goals: Goldman Sachs offers stability and capital preservation, while Interactive Brokers provides growth potential through technology-driven innovation.
