Is information risk priced for NASDAQ listed stocks?
Easley et al. (J Finance 57:2185 2221, 2002) building upon the asset pricing model of Fama and French (J Finance 47:427 465, 1992) show that the probability of informed trading (PIN) is a determinant of asset returns for NYSE listed securities. We extend this work by examining whether the PIN is a predictive factor for NASDAQ stocks, as many studies document significant differences between NYSE and NASDAQ listed securities. In the process we examine whether the use of PIN is appropriate for NASDAQ listed securities. We find that PIN and certain stock characteristics correlate differently for our sample of NASDAQ stocks than that of Easley et al. sample of NYSE stocks. We also determine that the risk of informed trading is only weakly priced for NASDAQ stocks. Contrary to Easley et al. we do not find evidence that excess returns increases as PIN increases.
