A good comparitive discussion:

"Every single contract that was shorted since May 4th by The Forces of Darkness and their tag-along, smartypant buddies is now under water. As the techies drive silver higher, the pain of being short becomes increasingly unbearable. (Kind of like how we all felt being long back in May.) More short covering will ensue and you get a virtuous cycle of higher prices.

Therefore, expect more explosive moves and higher prices next week. The only potential negative is that option expiration for the Sep11 contract is Thursday. Whether or not this will serve to contain the advance is difficult to predict. One thing I do know, though: I'm very excited for Monday. Tuesday, too." - ENDQUOTE

cheers!
