Hi Dave,
This was talked about recently and Mark Wagner explains it here:
In brief, the Stock Status report can be run for previous days but only for the part quantities. The costs on the report are whatever they are at the time the report runs using the part’s costing type (Standard, Average, etc.). I’ll be corrected if I’m wrong but that seemed to be the consensus.
It’s been recommended to do a snapshot of your PartCost table nightly so that you could do some revaluation if necessary in Excel.
