For the first time ever, I am making available the S&P 500 Monthly Total Returns going back to 1926.
I originally put this together years ago and have been religiously updating the information each month for the last ten years or so (what a life I have, right?).
My numbers vary slightly from the numbers found in the Ibbotson Year Book. I think the difference is due to rounding. My numbers come from percentages rounded to the nearest .00.
Anyway, I hope AFM readers find this helpful.
