There's no telling what one may uncover in the pink sheets. For example, thee are many small banks and transportation companies that prefer to remain unlisted. Many of these companies are very tightly held, and rarely does their stock become available to buy. Do to their inactivity, often times the spread between the bid and ask prices are very large. Some times one occasionally encounters a stock where there is only a bid price, and no offer price. This probably indicates that their is a buyer around trying to accumulate stock, and when ever shares become available, the market maker that is working with him, purchases the shares as soon as they become available for his account. If you should ever decide to accumulate a company like this, you could approach a broker dealer and ask if they could begin to make a market in the issue for you, as you hope to acquire a substantial position in the company. GLTU, and happy hunting.
