Based on projected money supply, I am predicting 2150 as what will be a midrange target for gold in 2013. I think 43 will be midrange for silver. Meaning the prices will trade on either side of those numbers, with those numbers being the center of an upcoming trading range.
Backing 15% of the Fed balance sheet, which is the historical low ratio, puts gold at 2150 after a year of QE 3 + 4. Silver at 50 to 1 is $43. These seem to be pretty reasonable low targets based on what I have observed as normal pricing during teh last few years.
