Plus, if we suddenly purchased that many that quick, you can bet that the cost of the shares would suddenly increase, and that would put money in the pocket's of Hasbro collective bunch of moneymongers...their profits would go up
Just a correction on how shares work. The ONLY times Hasbro gets money for a share purchase is when they are the seller of the shares, i.e. IPO, stock split.
As most of the shares out on the market are currently owned by private individuals or companies holding them as part of collective funds, those people or groups would collect the cash from any sale of their shares ... and not Hasbro.
