Liquidity Cost Determinants in the Saudi Market

Ahmed Alzahrani
Abstract—this paper examines liquidity as measured by both price impact and bid-ask spread. Liquidity determinants of large trades "block trades" in the Saudi market are examined using 124 companies that comprise all listed firms in the market. We use high frequency intraday data for the period 2005-2008 to provide out of sample evidence related to liquidity and information asymmetry. Bid-ask spread as a measure of liquidity was decomposed, using the model of Huang and Stoll (1997) to infer the information asymmetry patterns in the market. We use quoted spread (QBAS), relative spread (RBAS) and effective spread (EBAS) as three proxies for liquidity in the market. We find a price impact asymmetry between buyer-initiated block trades and seller-initiated block trades. Seller of block trades in the Saudi market pay higher liquidity premium than buyers of block trades. Our results provide new evidence from an order-driven market that has low degree of institutional investors and higher concentration of ownership.

Index Terms—Liquidity, price impact, Bid-ask spread block trades, Saudi stock market, information asymmetry.
