I am looking for a way to easily compute the TOTAL RETURN (dividends reinvested) of the US Total Stock Market Index and the International Total Stock Market Index (ex-US), from exactly 50 years ago TO DATE (like, actually through today's date, or yesterday's would be fine, but not 2010 or 2015, for example). Any resources?
If not, I will settle for S&P 500, DJIA, or another reasonable approximation of the index. I would strongly prefer the total market indices though, if possible. Thank you!
