Part of these percentages often is included in Institutional Holdings - making the combined total of these percentages over 100.

Market Makers The NASD member firms that use their own capital, research, retail and/or systems resources to represent a stock and compete with each other to buy and sell the stocks they represent. There are over 500 member firms that act as Nasdaq Market Makers. One of the major differences between The Nasdaq Stock Market and other major markets in the U.S. is Nasdaq's structure of competing Market Makers. Each Market Maker competes for customer order flow by displaying buy and sell quotations for a guaranteed number of shares. Once an order is received, the Market Maker will immediately purchase for or sell from its own inventory, or seek the other side of the trade until it is executed, often in a matter of seconds.
Market Maker Spread The difference between the price at which a Market Maker is willing to buy a security and the price at which the firm is willing to sell it i.e., the difference between a Market Maker's bid and ask for a given security. Since each Market Maker positions itself to either buy or sell inventory at any given time, each individual Market Maker spread is not indicative of the market as a whole. (see Inside Market)
