The Shiller P/E, or CAPE ratio, divides the price by ten years of inflation-adjusted earnings, smoothing out booms and busts. Robert Shiller made it famous as a long-term valuation gauge. This screen lists stocks on the London Stock Exchange with a cyclically adjusted P/E ratio below 12 and a return on equity above 10%, cheapest first. LSE prices are quoted in pence, and the list skips thinly traded shares.
