hedging is when a bank finances a project. For example if jinshan was hedge ( which they aren't) , it would sell its produced gold for $500 ( depending on the terms) an ounce to its financers . who would then sell it at its current price ($1000). In our case , jinshan cost is around $255an ounce , and it sells each ounce for the current price ($1000).

So if you hold any shares in hedge producers and your counting on gold to continue its rise , then selling them is recommeded. Since they are selling at a hedge or set price.
