We are not presenting this as a gambling opportunity. A bookie would be happy to take an infinite number of bets at rates that he has determined. We can only facilitate the trading of shares which are made available by you, the player. The price of the shares and the dividends paid are determined independently by market activity. We can not guarantee that the price of any athlete's stock will rise, or that it will even remain solvent.
Stock price is completely dependent on market activity.
We can not guarantee a stock will pay dividends. Even if an athlete performs above average, dividends must be generated by trading activity. We can not guarantee that the list price of a stock is the price at which you will be able to sell it. There must be a buyer to complete the transaction. Once you have purchased a stock there is no guarantee that you will be able to recover any of your money.
