I assume, like any listed stock with enough float, these "Shares" can be sold short? (Assuming the requisite deposits are retained in order to satisfy the order)
You assume correctly. Tradesports is completely zero-sum; for every long position there's a corresponding short position.
Yes, Tradesports can be sold short, I believe. But that doesn't affect the theoretical validity of Tradesports; someone being certain a candidate will NOT be chosen is as indicative as other being certain that candidate WILL be chosen... Or are you speculating that maybe someone is trying to purposely drive down the price of Luttig?
