Annual Growth Rate (CAGR): RTX 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: RTX's 24.4% CAGR means $1,000 grew by an average of 24.4% per year over 5 years, compounding to $2,978. The S&P 500's 12.4% CAGR turned the same $1,000 into $1,791. That 12.0% annual difference compounded into $1,187 more over 5 years.

The Bottom Line
RTX has historically outperformed the S&P 500 across most time periods analyzed. However, past performance doesn't guarantee future results, and individual stocks carry more company-specific risk. Many investors choose to hold both: index funds as a core holding and individual stocks like RTX for potential outperformance.
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.
