That does not make a difference cause every thing has to go through the issuer as far as buying and selling goes and the issuer just happens to be the ones who hold the lease on the ships, the leaser if you like.
So in other words for every seller or buyer there needs a market maker hired by the company for the company it is then the company through its market maker sells the shares for a profit or buys the shares for a depreciated price relative to the asking price the companies bid price.
The bid is always lower then the asking except when the company is selling were there is no bid.
The rules is buy on the bid and sell on the ask when there is no bid as long as there is a spread. Now should there be no takers and the company puts out a bid again then sell your loss and pick up the lower bid always working the spread on both the down side and up side cause don't forget you have a tax advantage on your loss against the up side expense.
