We analyze the information content of corporate insiders’ trades after accounting for certain trading patterns. Insiders spread their trades over longer periods of time when they have a longer lived informational advantage and when outside investors are less attentive. In contrast, they make isolated trades in short windows of time when their informational advantage is short-lived. Both isolated trades and trade sequences (those spread over multiple consecutive months) predict sizable abnormal returns; for sequences, these abnormal returns are manifest only following the completion of the sequence. The return patterns we identify continue to hold for a large group of insiders that would have been classified as “routine” traders by prior research, suggesting that informed insider trading may be even more widespread than previously thought.

С использованием данных о торговле инсайдеров определяются их разовые и серийные покупки (продажи). Серийные сделки могут быть использованы в построении лонг-шортовой стратегии - покупаем бумаги, по которым топы делали серийные покупки, продаем те, где были серийные продажи. По результатам в статье доходность может быть 20-30% годовых.
