We've recently witnessed Silver make a huge run from $27 to just under $35 recently (+30%). Gold went from $1565 to $1770 (+13%). And Platinum, once a stalwart of PM's which traded above gold for decades, went from $1380 to $1700 (+23%).
August 2011 was the first crossover of the Gold:Platinum ratio. In April 2010 it was 1.5:1, got as low as .87:1 in December 2011 and again in August 2012, and is currently .95:1. The 250 day moving average is below the 1:1 ratio; meaning that the weakness in Pt in relation to Au has been ongoing for 3 years.
I'm not sure if being a contrarian now is the right thing to do, and I have not been a big fan of the other white metals for the last 5 years, but I am finding prudence in the idea of diversifying my holdings by adding some Pt to my portfolio. I continue to like gold and silver, but this looks like an opportunity in Platinum.
