Hi, I have read that return of the S&P with dividends reinvested is 7, 8, or 9% a year. However that depends on what year you start. I would like to know where I can find the yearly returns and then do a study of every 20 years, year by year. For example: What is the return if I bought the S&P in 1980 and held it until 2000, and then What would it be if I bought it in 1981, 1982, 1983 etc. Thank you.
