This screen finds stocks with a Shiller P/E below 10. The Shiller P/E, or CAPE ratio, developed by economist Robert Shiller, divides the share price by the average of the last ten years of inflation-adjusted earnings, smoothing out business cycles and one-off years. A CAPE this low marks deep value: the stock trades at a small multiple of its decade-long earning power, a classic hunting ground for value investors.
