Intra-Period Timeliness, Adjusted

Click here for code to calculate Adjusted Intra-Period Timeliness (IPT_Adj) as developed in my 2018 "Robo-Journalism" RAST paper with Ed deHaan and Christina Zhu. Intra-Period Timeliness (IPT) is a measure of the speed of price reaction to a disclosure within a given window. Our adjustment modifies the traditional IPT measure to penalize for over-reactions and reversals. See Section 4.2.2 of the paper and related Internet Appendix for further details.
