There were two items of intraday commentary on the precious metals which you can find by scrolling down. The more important of them is linked below. I found it to be a little surprising this morning.
First Rogoff and now Scholes. Maybe Mackay was right, that men go mad in herds, but come back to their senses one at a time.
I also found this story to be interesting in a similar vein, although Stanley is not an economist.
