The document analyzes the performance and valuation of U.S. banks, highlighting their underperformance in comparison to the S&P 500 since the 2007 financial crisis and a tendency to trade at a discount compared to pre-crisis valuations. It discusses operational improvements and growth in revenue, but notes that banks' return on equity has not returned to pre-crisis levels and that non-performing loans have declined. Regulatory measures such as Basel III and the Dodd-Frank Act have been introduced to enhance the banking system's stability and resilience against future crises.
