Zacks Insider Score

Zacks has been collecting information on insider stock transactions since mid 2007. In order to predict which stocks are likely to outperform the market, we have developed a scoring system that is based on our collection of insider transaction information.


Since insiders tend to know what’s going on before the press does, traders watch for clusters of insider buying and selling activity to get a jump on potential market moving developments in the pipeline.


Zacks analysts have identified fourteen factors related to open market transactions, both buys and sells, which have taken place over the most recent one to six months, which can be used to predict returns over the next three to six months. The factors relate to agreement in terms of the number of buy versus sell transactions, magnitude in terms of the total change in insider holdings, and transaction size.


In recent testing, we've been able to achieve annualized portfolio returns as high as 48.84%. To see more details on the Zacks Insider Score, click here.
