You must bury the shares of your public company to reduce its float. Your investor relations costs will be lower if your public company has a lower float. [See my article on the proper use of shares.] The buried shares are deducted from your float and the balance is called the effective float. Your goal is to reduce the effective float to as near zero as possible. If your effective float is zero, you need not find buyers for your float because there are no shareholders selling their stock in your company. It is obvious that this is the best situation. If you want your company to be successful in every aspect, I recommend that you structure the float of your company this way.
Speculators, Not Investors
American stock buyers, on the whole, are speculators, not investors [http://www.iht.com/articles/529443.htm]. Stocks are bought with the intention of selling them quickly at a profit. Even the U.S. Government realizes that speculation doesn't lead to economic growth. Stock buyers who are willing to hold on to their shares for a minimum of one year pay less tax than those who trade in the Market quickly and sell their stocks. The American Government's tax incentive hasn't altered the speculative nature of the U.S. Market, because long term investors are consistent money losers. I've often wondered why these long-term investors continue to buy and hold shares in such a manner?
Avoiding Having Your Shares In the Market
I have been involved in the North American stock market for over 20 years and can confirm that professionals make more money by selling shares short (betting on the fall of the share price or the bankruptcy of the company) than by purchasing shares. There are over twenty ways to short sell stocks that are not listed in textbooks. (I have written a short selling article that lists twenty-four ways to short shares.) It is the only way to effectively defend against short selling. Make sure that your company shares are not in possession of the Depository Trust Company in New York.
When most people buy shares, they leave them "in street name" rather than taking possession of the share certificates. In street name, they are simply turned over to DTC. Short sellers rely or "borrow" street stock in order to sell shares that are not present on the market. Public short sellers anticipate paying back the "borrowed shares" at a much lower price when the stock crashes. Professional short sellers do not expect to be able to legally buy back the shares that aren't there and avoid paying U.S. tax on their profits. If the shares are not there to be borrowed, your company can't be sold short.
If you can prevent recommended reading your shares from being sold on the DTC by having your shareholders insist that they receive their certificates in person, then your company has a Cash Market. Few companies bother or understand the dangers they run from short sellers. Brokerage firms and the DTC work very hard to make it extremely difficult to create a Cash Market in any stock.
