Dislikedas for calling tops or a bubble he are some facts
in my opinion i dont think gold is overstreched nor over-valued if you see the charts and the annual returns on gold its not that overstreched nor over-valued:
2006 :22.9%
2007 : 31.3%
2008: 5.9%
2009: 24%
2010: 29.6%
2011 ytd: 4.7%
on the other hand silver because of the smaller market size compared to gold it was known as an easy to control and easy to minupilate market and its known for it high volitility thats way they call it the devils metal because of the high fluctiuation...Ignored
