Also, any MM or investment banks selling CFD s & futures contracts in GGP would for example on a Buy CFD they sell to a punter, hedge their risk by buying equivalent GGP shares. The buy would be on that firms principal trading book and again no need to report holdings.
If selling a future then given punters only need to put up about 20% of actual cost, any buying of shares to hedge needs to be nearer 4 x the size of the contract
