Interesting. Does Walmart have some important quarterly or annual results due to come out in the next six months? Because if so this could be an attempt to manipulate the corporate shrink figures.
I worked in that industry at one time. Was in a store with high shrink (go out to the parking lot, toss a rock in any direction, and it would have landed in a housing project). Corporate was always engaging in weird machinations to try and cover or explain our shrink. Window dressing for the stockholders.
