Insider Investment Horizon

Published: 01/23/2020   |   DOI: 10.1111/jofi.12878

FERHAT AKBAS, CHAO JIANG, PAUL D. KOCH

We examine the relation between insiders’ investment horizon and the information content of their trades with respect to future stock returns. We conjecture that an insider's investment horizon establishes a benchmark for expected patterns of continued trading behavior and thus helps identify unexpected insider trades, which should be more informative in efficient markets. Consistent with this conjecture, the trades of short‐horizon insiders are both more unexpected and more informed, on average, than those of long‐horizon insiders. Short‐horizon insiders and their firms also tend to display characteristics that are associated with a greater focus on short‐termism.


Informed Trading through the Accounts of Children

Published: 03/19/2013   |   DOI: 10.1111/jofi.12043

HENK BERKMAN, PAUL D. KOCH, P. JOAKIM WESTERHOLM

This study shows that the guardians behind underaged accounts are successful at picking stocks. Moreover, they tend to channel their best trades through the accounts of children, especially when they trade just before major earnings announcements, large price changes, and takeover announcements. Building on these results, we argue that the proportion of total trading activity through underaged accounts (labeled BABYPIN) should serve as an effective proxy for the probability of information trading in a stock. Consistent with this claim, we show that investors demand a higher return for holding stocks with a greater likelihood of private information, proxied by BABYPIN.


The Temporal Price Relationship between S&P 500 Futures and the S&P 500 Index

Published: 12/01/1987   |   DOI: 10.1111/j.1540-6261.1987.tb04368.x

This paper empirically examines the intraday price relationship between S&P 500 futures and the S&P 500 index using minute‐to‐minute data. Three‐stage least‐squares regression is used to estimate lead and lag relationships with estimates for expiration days of the S&P 500 futures compared with estimates for days prior to expiration. The results suggest that futures price movements consistently lead index movements by twenty to forty‐five minutes while movements in the index rarely affect futures beyond one minute.
