After that they have very little interest in the market. If it is declining too fast, they may support it occasionally by buying some stock and giving out some favorable news. That will make the market rally and they will sell out the newly acquired stock near the top of the rally. Manipulations of this kind appear to be going on nearly all the time, and there does not seem to be any limit to the number of suckers who fall for them. But then, one can't blame the public when you realize how thoroughly unreliable is most of the market information given to them. Still another kind of manipulation is "one-man" manipulation, where one man controls companies, which are known as "one-man" companies. Usually the directors of these companies are friends or employees of his, and in many instances he has their resignations in his possession, so that they must do whatever he wants them to do. Owing to the strict rules of the New York Stock Exchange, it is rather difficult for such manipulations to be carried on there. But there have been many of them on the New York Curb. When the Curb was operating on the street and was not under very much control, manipulations of this kind were very frequent. As an example, suppose a man of this kind has a mining company. When he wants the stock to go up, he sends the stockholders a great deal of information about the work at the mine, and perhaps sends them a telegram when a new vein of rich ore is found. The stockholders rush in to buy more stock, and that puts the price up. Then he unloads stock on them to the extent that they will buy it. In a day or two, the stock may drop back to less than one half of what it was selling at. If this "one-man" manipulator wants to buy any stock, he will give out a little unfavorable news, and he can get stock at his own price. After that the news is good or bad according to whether the manipulator wants to buy or sell, but as a rule he has an abundance of stock that he wants to sell, and is continually giving out good news. A few years ago there was a man operating in New York who promoted several companies and manipulated them in a large way. He is out of business now, but the same thing is still done in a smaller way. It is our opinion that more money is lost by the public in manipulated stocks than in promotion stocks, and we read a great deal about the enormous losses in them. Promotions that are failures may be perfectly legitimate and conducted in the utmost good faith, but manipulations are nearly always for the purpose of swindling the public. However, the lure of them is so great many people cannot withstand the temptations of them even after they have been "trimmed" several times. _PART FOUR_ TOPICS OF INTEREST TO SPECULATORS CHAPTER XVI. MARGINAL TRADING Most people who trade in stocks buy on margin. The ordinary minimum margin is about 20% of the purchase price, because banks usually lend about 80% of the market value of stocks.
