3. Total Return vs. Price Return: It’s important to note that the S&P 500 has two types of returns: price return and total return.

4. Calculation Example: Let’s illustrate the calculation process with a hypothetical example:
   • Beginning Value (January 1, 2023): 4,000
   • Ending Value (January 31, 2023): 4,200
   • Dividends Received: $20

   Monthly Return = (4,200 – 4,000 + 20) / 4,000 = 0.055 or 5.5%

5. Compounded Returns: To calculate the compounded monthly returns, you can use the formula:Compounded Return = (1 + Monthly Return1) * (1 + Monthly Return2) * … * (1 + Monthly ReturnN) – 1

   Where Monthly Return1, Monthly Return2, …, Monthly ReturnN are the monthly returns for each respective month in the holding period.
