Editing Commodity (section)

== Inventory data ==
The [[inventory]] of commodities, with low inventories typically leading to more volatile future prices and increasing the risk of a "[[stockout]]" (inventory exhaustion). According to economist theorists, companies receive a [[convenience yield]] by holding inventories of certain commodities. [[Data]] on inventories of commodities are not available from one common source, although data is available from various sources. Inventory data on 31 commodities was used in a 2006 study on the relationship between inventories and commodity futures risk premiums.<ref>{{Cite SSRN|last=Gorton |first=GB |display-authors=etal |year=2007 |ssrn=996930 |title=The Fundamentals of Commodity Futures Returns}}</ref>
