Using the BDH function of Bloomberg's excel add-in, I was given a historical database of fund prices covering the years 2000 through November 2020. The issue is that a fund frequently replicates its final price from the time of extintion until November 2020.
For illustration, suppose a fund was terminated in 2015 at a price of 5.25; in this case, the price of 5.25 is displayed from 2015 until nov/2020, which is obviously worthless. I want to know if the parameterization of the BDH function is the issue or if this function always returns data in this manner.
