A combined value screen developed by Richard Beddard, editor of leading UK finance site, Interactive Investor. It selects 30 UK-listed companies (with a market value of more than £500 million), using an approach that assesses three key criteria: i) value, as measured by the earnings yield; ii) profitability, measured by return on capital; and iii) financial strength, as measured by Piotroski’s F-Score. Essentially Piotroski plus the Magic Formula. This screen is not to be confused with the Thrifty Thirty, which is Beddard's own stock picks, as described on the Interactive Investor Blog. more »
