It is unquestionable that only a small part of the transactions upon the Exchange is of an investment character; a substantial part may be characterized as virtually gambling. Yet we are unable to see how the State could distinguish by law between proper and improper transactions, since the forms and the mechanisms used are identical. Rigid statutes directed against the latter would seriously interfere with the former. The experience of Germany with similar legislation is illuminating. But the Exchange, with the plenary power over members and their operations, could provide correctives, as we shall show. MARGIN TRADING Purchasing securities on margin is as legitimate a transaction as a purchase of any other property in which part payment is deferred. We therefore see no reason whatsoever for recommending the radical change suggested, that margin trading be prohibited. Two practices are prolific of losses--namely, buying active securities on small margins and buying unsound securities, paying for them in full. The losses in the former case are due to the quick turns in the market, to which active stocks are subject; these exhaust the margins and call for more money than the purchasers can supply. The losses in the latter case are largely due to misrepresentations of interested parties and unscrupulous manipulations. To correct the evils of misrepresentation and manipulation, we shall offer in another part of this report certain recommendations. In so far as losses are due to insufficient margins, they would be materially reduced if the customary percentage of margins were increased. The amount of margin which a broker requires from a speculative buyer of stocks depends, in each case, on the credit of the buyer; and the amount of credit which one person may extend to another is a dangerous subject on which to legislate. Upon the other hand, a rule made by the Exchange could safely deal with the prevalent rate of margins required from customers. In preference, therefore, to recommending legislation, we urge upon all brokers to discourage speculation upon small margins and upon the Exchange to use its influence, and, if necessary, its power, to prevent members from soliciting and generally accepting business on a less margin than 20 per cent. PYRAMIDING “Pyramiding,” which is the use of paper profits in stock transactions as a margin for further commitments, should be discouraged. The practice tends to produce more extreme fluctuations and more rapid wiping out of margins. If the stockbrokers and the banks would make it a rule to value securities for the purpose of margin or collateral, not at the current price of the moment, but at the average price of, say, the previous two or three months (provided that such average price were not higher than the price of the moment), the dangers of pyramiding would be largely prevented.
