Nitheesh, thanks for the article. I'm a big fan on Ben Graham and value investing. I wanted to say, though, that the forumla you shared is something he was trying to come up after he retired to make investing easier for the masses. In the end, it wasn't particularly successful. Most Ben Graham style investors, myself included, stick with asset value (AV) and earnings power value (EPV). These are more complicated than the shorthand provided, but likely more useful.

Cheers!
