"Dividends have also been div and split adjusted", what does that mean?
The new Close values are unadjusted but all other fields are split adjusted, the adjusted close being the relevant field. This is why the Close can appear higher. There are no dividend adjustments that I can find. Do you have symbol examples?
For example, NKE 2000-03-16 dividend was $0.0075 per share. 1987-09-04 dividend is $0.0006 per share. These numbers seem too small, like they were split adjusted as well.
