Though known as perhaps the greatest value investor of all-time, Warren Buffett’s approach involves much more than just looking at value, Validea CEO John Reese writes in his latest Forbes column.

“To label Buffett a ‘value investor’ is probably an oversimplification,” writes Reese. He cites a recent study from AQR Capital Management’s Andrea Frazzini, David Kabiller, and Lasse H. Pedersen, which found that “the secret to Buffett’s success is his preference for cheap, safe, high-quality stocks combined with his consistent use of leverage to magnify returns while surviving the inevitable large absolute and relative drawdowns this entails.”

Reese says the findings didn’t come as a surprise to him, because the Buffett-inspired Guru Strategy he has employed for many years uses metrics that target safer, high-quality stocks. He talks about how his Buffett-based model works, and looks at a few stocks it’s high on right now. Among the picks: FactSet Research Systems.
