Trading Mechanisms and the Components of the Bid-Ask Spread


  • Affleck-Graves, John
  • Hegde, Shantaram P
  • Miller, Robert E


The authors compare the relative magnitudes of the components of the bid-ask spread for New York Stock Exchange (NYSE)/American Stock Exchange (AMEX) stocks to those of National Association of Securities Dealers Automated Quotations (NASDAQ)/National Market System (NMS) stocks. They find that the order-processing cost component is smaller, and the adverse selection component is greater, on the NYSE/AMEX trading systems than on the NASDAQ/NMS system. The inventory holding component is also greater for exchange-traded stocks than for NASDAQ/NMS stocks, but this may be attributable to differences in the characteristics of the firms whose stocks trade on the respective systems.
