How Does BAC Compare to the S&P 500?

The S&P 500 represents the 500 largest U.S. companies and is considered the benchmark for "market returns." If BAC consistently beats the S&P 500, it suggests the stock has delivered alpha—returns above what you'd get from passive index investing.

Annual Growth Rate (CAGR): BAC vs S&P 500
What is CAGR and Why Does It Matter?
CAGR (Compound Annual Growth Rate) is the smoothed annual return that shows how an investment grew as if it increased at a steady rate each year. Unlike simple average returns, CAGR accounts for compounding—the effect of earning returns on your returns.
Why use CAGR instead of total return? Total return tells you the final result, but CAGR tells you the pace of growth. A 100% total return over 5 years sounds great, but that's only ~14.9% CAGR. A 100% return over 10 years is just ~7.2% CAGR. CAGR lets you compare investments across different time periods on an apples-to-apples basis.
Example: BAC's 6.5% CAGR means $1,000 grew by an average of 6.5% per year over 5 years, compounding to $1,371. The S&P 500's 12.4% CAGR turned the same $1,000 into $1,791. That 5.8% annual difference compounded into $420 more for the index over 5 years.

Note: We use SPY (SPDR S&P 500 ETF) as the S&P 500 benchmark. SPY has a small expense ratio of 0.09% which may cause slight underperformance compared to the actual S&P 500 index over very long periods.
