link traders as closely as if they were seated in the same room. With the help of computers, price quotations from dealers in Seattle, San Diego, Atlanta and Philadelphia can be flashed on a single screen. Dedicated telephone lines link the more active traders. Confirmations are delivered electronically rather than through the mail. Dealers thousands of miles apart who are complete strangers execute trades in the thousands or even millions of dollars based on thirty seconds of telephone conversation and the knowledge that each is a securities dealer registered with the National Association of Securities Dealers (NASD), the industry self-regulatory organization that supervises OTC trading. No matter which way market prices move subsequently, each knows that the trade will be honoured.
2. TRADING ON THE STOCK EXCHANGE FLOOR
When an individual wants to place an order to buy or sell shares, he contacts a brokerage firm that is a member of the Exchange. A registered representative or “RR” will take his order. He or she is a trained professional who has passed an examination on many matters including Exchange rules and producers.
The individual’s order is relayed to a telephone clerk on the floor of the Exchange and by the telephone clerk to the floor broker. The floor broker who actually executes the order on the trading floor has an exhausting and high-pressure job. The trading floor is a larger than half the size of football field. It is dotted with multiple locations called “trading posts”. The floor broker proceeds to the post where this or that particular stock is traded and finds out which other brokers have orders from clients to buy or sell the stock, and at what prices. If the order the individual placed is a “market order”–which means an order to buy or sell without delay at the best price available–the broker size up the market, decides whether to bargain for a better price or to accept one of the orders being shown, and executes the trade–all this happens in a matter of seconds. Usually shares are traded in round lots on securities exchanges. A round lot is generally 100 shares, called a unit of trading, anything less is called an odd lot.
When you first see the trading floor, you might assume all brokers are the same, but they aren’t. There are five categories of market professionals active on the trading floor.
Commission Brokers, usually floor brokers, work for member firms. They use their experience, judgment and execution skill to buy and sell for the firm’s customer for a commission.
Independent Floor Brokers are individual entrepreneurs who act for a variety of clients. They execute orders for other floor brokers who have more volume than they can handle, or for firms whose exchange members are not on the floor.
Registered Competitive Market Makers have specific obligations to trade for their own or their firm’s accounts–when called upon by an Exchange official–by making a bid or offer that will narrow the existing quote spread or improve the depth of an existing quote.
Competitive Traders trade for their own accounts, under strict rules designed to assure that their activities contribute to market liquidity.
And last, but not least, come Stock Specialists. The Exchange tries to preserve price continuity– which means that if a stock has been trading at, say, 35, the next buyer or seller should be able to an order within a fraction of that price. But what if a buyer comes in when no other broker wants to sell close to the last price? Or vice versa for a seller? How is price continuity preserved? At this point enters the Specialist. The specialist is charged with a special function, that of maintaining continuity in the price of specific stocks. The specialist does this by standing ready to buy shares at a price reasonably close to the last recorded sale price when someone wants to sell and there is a lack of buyers, and to sell when there is a lack of sellers and someone wants to buy. For each listed stock, there are one or more specialist firms assigned to perform this stabilizing function. The specialist also acts as a broker, executing public orders for the stock, and keeping a record of limit orders to be executed if the price of the stock reaches a specified level. Some of the specialist firms are large and assigned to many different stocks. The Exchange and the SEC are particularly interested in the specialist function, and trading by the specialists is closely monitored to make sure that they are giving precedence to public orders and helping to stabilize the markets, not merely trying to make profits for themselves. Since a specialist may at any time be called on to buy and hold substantial amounts of stock, the specialist firms must be well capitalized.
