I'm not liking my silver (or oil) much anymore. However, I expect the dollar to soften, and more middle east tension, and so they should run up again some day. Hopefully soon.
What you want to remember, is that any leveraged ETF like AGQ is not beingg traded by the arbitrageuers in the extended hours...the ones who trade futures and swaps to make it a tripler...you are seeing the retailers jockeying for position, getting ready for tomorrow......which in this case is a good thing since it is going up for you...
