Corporate insiders in publicly traded companies, such as top executives and directors, know more about their firms than the market does. Therefore, within their insider transactions hides the most lucrative information of all – private information. The investment rationale suggests that by mimicking the actions of insiders, both sell and buy transactions, one can achieve a higher return than a simple buy and hold strategy. However, due to insider-specific incentives and trading noise, it is important not only to follow all the insiders’ transactions but also to identify which transactions are informative.
CORPORATE INSIDER TRADING SIGNAL
The Insider Transactions signal tracks the aggregated insider actions and ranks stocks from the Most Insider Bought to the Most Insider Sold.
All Form 4 filings are scanned and categorized in TipRanks’ database. To eliminate the noise included in the non-informative actions, an important part of the signal construction is identifying which of the transactions are informative. We include only transactions that have a clear buy or sell motivation and exclude transactions that are more ambiguous or automatic in nature.
The magnitude of the Insider Transaction signal depends on several factors including time passed from the transaction, the type of transaction (Buy or Sell), the number and size of transactions, and several normalizing and statistical adjustment factors.
Stocks are then ranked with a score of 10 to 0, with 10 having the strongest insider transaction trend to 0 having the weakest.
