This is a 28min video from Grant Williams of Vulpes Investment management (Singapore hedge fund managers). Grant is the author of the much acclaimed Things that make you go Hmmmmmmm!. The presentation details two bubbles, one about to burst and the other about to inflate enormously.
There is much money to be lost in the bursting by the unwary and conversely a great deal to be made by hitching a ride up with the other.
