My point is there is someone on each side of the transaction, (yes there are spreads and commissions). For each Seller there is a Buyer, for each Buyer there is a Seller.
The sum of money is the same, it is distributed differently. People are acting as if wealth suddenly evaporated in China, but it was redistributed within China. I am pretty sure China still only lets citizens own shares. So all the wealth is still there the seller are getting less than they hoped but the buyers are paying less.
