Illiquidity as a Priced Factor: Evidence from Intradaily Data

Sahn-Wook Huh

published: 2009 | Research publication | Speaker Series Document


A number of proxies for illiquidity have been proposed in the literature that relates trading costs to asset prices. However, some of the illiquidity measures provide equivocal relations to returns. Other measures conceal important dynamics underlying highfrequency data because they are constructed from daily or lower frequency databases. In this study, we adopt a direct and intuitive approach to estimating illiquidity. Specifically, we estimate a set of price-impact parameters based on four different models using the intradaily order flows processed via the Lee and Ready (1991) algorithm from the tickby-tick databases for NYSE stocks over the past 23 years. Our empirical results provide strong evidence that illiquidity measured by the price-impact parameters is priced in the cross-section of stock returns, even after controlling for risk factors, firm characteristics, and other illiquidity proxies prevalent in the literature. Consistently high levels of statistical significance also suggest that the price-impact parameters estimated using theintradaily order flows are more reliable proxies for illiquidity.
