At Zacks, we've championed independent research since 1978, when our founder, Len Zacks, published a highly influential paper which first detailed his innovative investment approach: analyzing earnings estimate revisions and surprises to predict stock movements.

Since then, Zacks has continually expanded and refined that research to help institutions and high net worth clients invest more effectively. Today, Zacks Investment Research is one of the largest equity research providers in North America.
