Testing the PIN variable

Abstract

This paper puts the PIN variable (Probability of INformation-based trading) to test. We ¯nd that for a large set of stocks, the PIN vari- able is lower (albeit insigni¯cantly) in the periods before earnings an- nouncements dates than in the periods after earnings announcements dates. This is inconsistent with the idea of PIN capturing the proba- bility of informed trading
