Stock prices in beta 7 are stupid. They become incredibly high the less peopel there are left in the game, and stock is valued incredibly highly. If you own 6 of your own stock, and your opponent owns 4 of yours, you can buy back your own stock and it actually reduces your opponents buyout percentage because your own stock price rises so much because you own yourself. Fortunatly due to the nature of team games this shouldn't be much of a problem for the tournament, but it's very apparent in a FFA game. A 1.8 million buyout price should not be happening in OTC, ever, but that's the standard in beta 7.
