Another field to which a member may turn is that which has to do with transactions in bonds. The “bond-crowd,” as it is called, makes its headquarters on a platform under the east gallery. There are about fifty of these “bond-men,” and the compensation paid them for their service is the same as that paid on stocks, ten thousand dollars in bonds being reckoned equivalent to 100 shares. As there are twice as many bonds as stocks listed on the Exchange, one would think a larger number of brokers than this little coterie would be required to handle the transactions, but, despite this disparity in the relative size of the lists, it so happens that very many of the listed bond issues are rarely dealt in, and hence there is no surplus business. Moreover, brokers from all parts of the room are constantly executing their own bond orders without having recourse to the assistance of brokers who make this department a specialty. Still another opportunity presents itself in the business of arbitraging. The arbitrageurs stick closely to the rail along the south wall, where there are pneumatic tubes connecting with the cable offices downstairs. Their business is one that calls for the utmost speed, since it involves taking advantage of fractional differences that arise from time to time in the prices of stocks that are listed on foreign Bourses as well as on the New York Stock Exchange. Thus Canadian Pacific may sell at 270 in London and at the same time at 269½ in New York, and as an excellent cable service keeps pace with these fractional differences, the arbitrageur may buy in New York and sell in London and receive a confirmation, all within three minutes.[96] Because of its complexity and its risks, arbitraging is not a business that appeals to beginners on the floor. One must have reliable colleagues on the foreign Exchanges who are constantly watchful and alert, and who are moreover possessed of sufficient capital to finance large transactions. In addition, there are labyrinthine difficulties to surmount in the way of commissions, interest charges, insurance of securities in transit, fluctuations in the money markets abroad and at home, cable tolls, letters of confirmation, rates of foreign exchange, settlement days, contangoes, and many other matters. Unless a man has had a long experience in the difficult art of arbitraging, he had better shun it or prepare for trouble.
