Supplies investments (6)
I believe the answer is:
stocks
I believe this clue is a double definition.
'supplies' is the first definition.
(stocking is a kind of supplying)
'investments' is the second definition.
(I've seen this before)
(Other definitions for stocks that I've seen before include "Village greens used to have these" , "bloomers" , "Plants; form of punishment" , "Securities, investments" , "Supplies of goods in store" .)
