Even with today's "explosion", neither gold nor silver is even back up to where they were earlier this month. With the prices so manipulated, I really don't put much stock in short term movement. Wake me when they surpass their previous highs- gold over $2k and silver over $50.
And while the increases matter if you hold physical, gold and silver prices don't really have much to do with the price of SFMI, and won't until SFMI gets its act together and there is a better correlation between the price of gold and the amount in WEM.
