A Bad Day For GBN.V Shares
Considering that dynamic hedging strategies now form the basis of the market, and that probably gold mining shares are the favourite prey for commercial traders providing liquidity for the markets and that this has been an established practise since the 1990's when dynamic hedging came into vogue, you would look at how long term bond yields are performing.
GBN.V shares are strongly inversely correlated with long-dated U.S. treasuries, this is an absolute fact.
So on any given day when GBN.V truly sucks, then yields are likely on the decline, and treasury bond prices are on the rise.
