      On the subject of key market makers, don't believe for a moment thatthey are all the same. Goldman Sachs (GSCO), Merrill Lynch (MLCO), BearStems (BEST), Morgan Stanley (MSCO), and Solomon Smith Bamey (SBSH) arewidely known to be big players in the stocks that they make markets in. Notonly do savvy traders follow their every move, other market makers do aswell. In my opinion, GSCO is the most reputable, highly regarded, powerfulmarket maker on the street. GSCO is not the key market maker in all stocksthat it makes a market in. Nevertheless, when GSCO starts to getaggressive, everyone takes note. By paying close attention to GSCO'sactions (number of times at inside quote, confirmation of trades on theTOS, the general movement of its bids and offers around the inside quote,etc.) a trader can develop a good "feel" for the movement of the stock. Icannot count the times that an action by GSCO has been followed by the sameaction by other market makers.
