Returns include price changes and reinvested dividends, with recent total returns showing strong recent years but also significant downturns, emphasizing market volatility.

Key Takeaways

• Volatility is Normal: Returns fluctuate wildly year to year; averages smooth out these peaks and troughs. 
   

• Total Return Matters: Always consider dividends, as they significantly boost overall performance. 
   

• Past Performance ≠ Future Results: While historical averages are useful, they don't guarantee future returns.
