You bought shares on the secondary market above the listing price. You are only receiving money at the listing price. i.e.: 1. shares listed at $20, I buy one, paying Ackman $20 2. I sell it to you for $30, you pay me that money 3. Ackman returns $20 to you It also works the other way around if you bought it from me below $20. You'd make a profit.
