المستخلص: This study aimed at suggesting a model for the main determinants of the bid-ask spread in the Amman Stock Exchange. Daily trading data for 50 selected companies, during a 6 years’ time period from 2001 to 2006, was collected from ASE publications. The suggested explanatory variables (security's specific factors: stock price, price volatility, trading volume, number of trades), company’s specific factors: firm size, industry affiliation, ownership concentration, ownership type, and financial performance), and stock market’s specific factors (tick size)), were significantly affected the relative bid-ask spread in ASE except the industry affiliation variable. Also, the cross-sectional variation in spreads in ASE is due primarily to differences in information asymmetries and differences in order processing cost. The study suggests that ASE should implement a multiple tick sizes, by defining small number of price ranges with different (low) tick sizes. The study emphasizes the need for stock ranking system to use it as a proxy for the security risk, since the bid-ask spread is a positive function of security risk
