Why is PIN Priced?

Recent empirical work suggests that a proxy for the probability of informed trading (PIN) is an important determinant of the cross-section of average returns. This paper examines whether PIN is priced because of information asymmetry or because of other liquidity effects that are unrelated to information asymmetry. Our starting point is a model that decomposes PIN into two components, one related to asymmetric information and one related to illiquidity. In a two-pass Fama-MacBeth regression, we show that the PIN component related to asymmetric information is not priced, while the PIN component related to illiquidity is priced. We conclude, therefore, that liquidity effects unrelated to information asymmetry explain the relation between PIN and the cross-section of expected returns.
