Of course, every trader gets market letters from one or more brokers. These are many and varied in character. Some of them are prepared with great care and give reliable information, but you must remember that a broker's market letter is published for the purpose of getting business, and business is created only by the customers' trading. Therefore it is to the broker's interest to have his customers make many trades instead of a few trades. In his book "Business Barometers," Roger W. Babson reproduces a letter written to him by the Manager of the Customers' Room of a Stock Exchange House. We consider this letter so important to all traders, we are taking the liberty to reproduce it here: "Hearing on every hand about the fortunes made in Wall Street, I decided, upon being graduated from college, to devote myself to finance. With this end in view, I secured a position with a first-class New York Stock Exchange House, finally becoming the 'handshaker' for the firm; that is, 'manager' of the customers' room. So I had an exceptional opportunity to size up the stock business. The chief duties of the manager are to meet customers when they visit the office, tell them how the market is acting, the latest news from the news-tickers and the gossip of the Street. But the real duties are to get business for the house. Once a most peculiar man came to the office. He was about forty-five years of age, dressed in a faded cutaway coat, high-water trousers, and an East Side low-crown derby hat. In a high squeaky voice he said that he knew our Milwaukee House and would like to open an account. Of course, we were all smiles, for here was a new 'customer.' "One day while in Boston he called us up on the long-distance telephone to make an inquiry about the grain market. One of my assistants, desiring to get a commission out of him, said 'We hear that Southern Pacific is going up; you had better get aboard.' He said 'All right; buy me a hundred at the market.' The stock was bought, but he never saw daylight on his purchase, for the market declined steadily afterward and by the time he got back from Boston it showed a heavy loss. The man who advised its purchase had no special knowledge about the stock, but simply took a chance, knowing that the market had only two ways to go, and it might go up, in which case, besides making twenty-five dollars in commissions for the house, he would be patted on the back for his good judgment. If the market went down, as it did, he would still make twenty-five dollars.
