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 »

Companies with a score of 8 or 9 have been found as a group to outperform weak stocks by 7.5% annually over a 20 year period. The weakest stocks, scoring 2 or lower, were found by Piotroski to be five times more likely to fall into financial problems.
The price-to-book ratio, or P/B ratio, is a financial ratio used to compare a company's book value to its current market price and is a key metric for value investors. Book value denotes the portion of the company held by the shareholders; in other words, the company's assets less its total liabilities. This is calculated as the Current Price divided by the latest annual Book Value Per Share (The inverse ratio is known as book to market). We exclude preferred shares in the calculation of Book Value.
As with most ratios, it varies a fair amount by industry (companies that require more infrastructure capital will usually trade at P/B ratios much lower than, for example, consulting firms). P/B ratios are often used to compare banks, because most assets and liabilities of banks are constantly valued at market values. This version includes intangible assets and goodwill, unlike price to tangible book value. The price / book value ratio rarely falls below 1
