Historic
From ACT Wiki
Measures based on actual past data, rather than forecast future data.
For example the historic dividend yield is normally based on the most recent past dividend.
(As opposed to the prospective dividend yield which is normally based on the next forecast future dividend.)
Another example is the historic Price to earnings ratio (PER) which is normally based on the earnings for the most recent past period.
(As opposed to the prospective PER which is normally based on the projected earnings for the nearest future forecast period.)
