I was looking for both the daily adjusted close and the normal close of the S&P500. On Yahoo Finance i found data that included both of these prices, but the two were identical. These are the R-commands i've used:


I also tried it with python, but the same thing happened. The adjusted close and close were equal on every day. Is that a bug? Or is there no difference between the two?
