The dataset consists of 644,643 corporate insider transactions between January 1986 and December 2013 that were filed to the Securities and Exchange Commission using Form 4 under Section 16 of the Securities Exchange Act of 1934. The original filings contain information on the identity of the trader, the role within the firm, the number of shares that were bought or sold, the transaction price, the total share position of the respective trader, the date of trade, and the date of reporting. The data on trades are merged with other characteristics of the insider or the firm.

The dataset is used to investigate insider trading quantities and dollar profits to measure the benefits that insiders extract from their superior information. We describe and quantify the dollar profits, study the relation between trading returns and trading quantities and explore the determinants behind this relation.
