IAU will track spot gold. Spot gold could see a bounce going into 2016. We've seen this for the past two years, and hitting lows in December seems to set the table for the coming year. Still a long-term bear until proven otherwise.
Hedge Funds dress down their losers and individuals take tax losses in December. Commodities probably bounce again in the first quarter of the new year. The sell-downs in POT and MOS have been brutal but a bounce is coming.
