Piotroski F-Score Price to Book Value Screen

The Piotroski F-Score P/B is the classic value strategy by famous finance academic Joseph Piotroski. Originally published in a 2000 research paper titled "Value Investing: The use of historical financial statement information to separate winners from losers", the strategy hunts for the highest quality shares amongst a deep value basket. In this version of the screen, the cheapest 20% of the market by their Price to Book ratio are first selected, and filtered further to find those with the most improving fundamental health trends using the Piotroski F-Score. Piotroski developed the F-Score system after observing that: "In that mix of bargain companies, you have some that are just stellar. Their performance turns around. People become optimistic about the stock, and it really takes off. However half of the firms languish; continue to perform poorly and eventually delist or enter bankruptcy." Piotroski's back-tests over 20 years showed that his formula could improve the returns from typical value investing strategies by at least 7.5% annually and is especially effective amongst small caps. Investors should beware the low liquidity shares in this screen can be expensive to trade. more »

Piotroski F-Score Price to Earnings Value Screen

The Piotroski F-Score P/E is a value strategy developed by the renowned finance professor Joseph Piotroski, published in a 2000 research paper titled "Value Investing: The use of historical financial statement information to separate winners from losers". The strategy hunts for the best quality shares amongst a deep value basket. In this version of the screen, the cheapest 20% of the market by their P/E ratio are selected, and filtered further for the highest scoring companies using a nine-point fundamental checklist called the Piotroski F-Score. Piotroski developed the system after observing that: "In that mix of bargain companies, you have some that are just stellar. Their performance turns around. People become optimistic about the stock, and it really takes off. However half of the firms languish; continue to perform poorly and eventually delist or enter bankruptcy."

Piotroski High F-Score Screen

The Piotroski F-Score Screen is a quality strategy outlined by the famed academic Professor Joseph Piotroski and investigated further in a 2011 paper titled "Identifying expectation errors in Value/Glamour stocks". The strategy hunts for the best quality shares in the market regardless of price. In this version of the screen we have selected the highest scoring stocks in the market using Piotroski's nine-point fundamental checklist called the F-Score. While the F-Score was originally used only for filtering value stocks, Piotroski discovered it was just as effective for filtering glamour stocks: "Firms experiencing the strongest improvement in fundamentals (FSCORE ?7) generate a mean size-adjusted return of 5.5 percent annually". What Piotroski essentially was saying was that the highest scoring stocks returned 5.5% more than the market - these findings have been backed up by independent research by Societe Generale. Perhaps as a result the F-Score has become extremely popular with investors and is a core component of the Stockopedia StockReports. more »
