Today, Screener.co founder Lenny Grover published a blog on FinScreener.org extolling the benefits of using a stock screener in the investment process.  From the article:

"Core to my belief in the importance of powerful screening tools is a relief belief that if you prospect in the same narrow company universe as everybody else, it will be harder to consistently differentiate yourself with superior returns. Casting a wider net, and looking off the beaten path for investment opportunities, is especially important for value investors"

If you are curious as to how screening can benefit your investment process, this article is informative.
