I've trashed this sites methodology here before. Its complete #$%$ when it comes to panl.
"Our proprietary screening process stacks up opportunities based on 27 valuation measures. ...
Our value score is based on a simple priciple that past fundamental results mean something. 80% of the score is based on past results, 20% is based on forward looking estimates. "
Well guess what using 80% of 27 valuations measures that look back on panl is like riding a bullet train looking backward just as it pulled out of the train station. its #$%$.
by they way they spelled principle wrong.
