No idea about his specific fund's pricing but the "traditional" pricing model for hedge funds is 2 and 20, ie, 2% of assets under management plus 20% of profits.

But also, a performance fee is kind of like an option in that it has an asymmetrical payoff - if you make 100 in profit, you get 20, but if you lose 100, you don't have to pay 20. All other things being equal, the expected value of a performance fee will increase with portfolio size as long as there is a chance you are right (and there is always a chance you are right).

Yes, the predicted events will have to come to pass eventually to collect on the performance fee. Nobody (not even this guy) knows when that will happen, but everyone knows that it will happen eventually, and in the meantime, you can position yourself so as to maximise the payoff when they do.
