Piotroski High F-Score Screen

Josef Piotroski came up with a simple nine criteria scoring system to help identify bargain stocks in recovery.  It is known as the F-Score and is used extensively throughout Stockopedia on Stock Reports and in screens as a measure of an improving financial health trend.  But while his now famous original strategy (which we have modelled here) focused on applying the F-Score filter to only the cheapest stocks in the market, other analysts have discovered that the highest F-Scoring companies in the market in aggregate also outperform.   We have filtered the market in this strategy to just highlight the companies showing a Piotroski F-Score of 9. more »

Philip Fisher Growth Screen

This is a growth screen based on the approach of the late Phil Fisher, one of the great investors of all time and the author of the classic book Common Stocks and Uncommon Profits. Fisher started his money management firm, Fisher & Co., in 1931 and over the next seven decades made tremendous amounts of money for his clients. Philip Fisher had a famous 15 point checklist for investing in stocks. Even though it includes numerous qualitative factors, it's possible to glean some key quantitative criteria too: Consistently strong profitability; Consistent sales growth; Growth exceeding industry norms; Little or no dividend payout; and Reasonable price compared to future growth prospects You can read more about Philip Fisher's approach here. more »

Large Cap Dividend Attraction Screen

This is a large-cap dividend focused screen, loosely based on the "Dividend Attraction" screen discussed by Kevin Matras in his useful book, "Finding Number 1 Stocks". It focuses on the added dividend security to be found amongst larger-cap stocks in a credit-constrained environment. In Matras' version, however, the primary filter is the Zacks Rank (a proprietary metric analysing analyst forecasts for i) Agreement, ii) Magnitude, iii) Upside Potential, Surprise). However, this version just uses the 3 month change in analyst forecasts instead. The other elements are: i) A market capitalisation above £1.5 bn, ii) Positive 5 Year Dividend growth, iii) Above Average Return on Equity, iv) Above Average EPS Growth and v) Price to Operating Cashflow. more »

Martin Zweig Growth Screen

A Growth at a Reasonable price (GARP) investing strategy that uses both fundamental analysis and market timing. It focuses on strong growth in earnings and sales, a reasonable price-earnings ratio given the company's growth rate, insider support, and relatively strong price action. Martin E. Zweig was a reputed US growth money manager back in the 1990’s as well as an investment newsletter writer. He was named stock picker of the year 2 times in a row and wrote a book titled “Winning on Wall Street”, which outlines his investing strategy. Zweig is essentially a growth investor but with a conservative streak, focusing on selecting growth stocks with certain value characteristics, through a system that uses both fundamental analysis and market timing. more »

Benjamin Graham Defensive Investor Screen

A demanding intrinsic value-based screen designed for less experienced investors which focuses on “important” companies with long histories of profitable operations and strong financial condition. Graham felt defensive investors should confine their holdings to the shares of large, prominent, and conservatively financed companies with long histories of profitable operations. By this, he meant a firm of substantial size and with a leading position in its respective industry. Additionally, Graham sought companies with: 1) Strong financial position (based on the current ratio & debt to working capital). 2) 20 years of uninterrupted dividends 3) No negative earnings in the last 10 years & a 10-year annual earnings growth rate of at least 3% 4) A reasonable price-earnings ratio & a moderately low ratio of price to assets more »

Greenblatt's Magic Formula

This screen implements the Magic Formula value investing strategy pioneered by hedge fund manager, Joel Greenblatt. It is based on buying 20-30 "good, cheap companies" defined as having the best available combined MFI ranking in terms of Earnings Yield and a Return on Capital.  Greenblatt argues that return on capital is the best determinant of whether a business is a good one or not (companies that can earn a high ROC over time generally have a special advantage that keeps competition from destroying it, such as a unique business model). Earnings yield is his metric for 'cheapness'. Greenblatt believes that stock prices of a firm can experience “wild” swings even as the value of the company stays relatively constant giving investors opportunities to buy low and sell high. more »

Price Momentum Screen

A momentum screen based on buying prior winning stocks and selling short prior losers based on the empirical observation that Investments exhibit persistence in their relative performance. Buying winners inherently conflicts with the contrarian philosophy that is part and parcel of many successful investors. Nevertheless, it has long been noted by traders that good performing investments tend to continue to do so, whereas those that have performed relatively poorly tend to continue on the same path. This screen looks for high relative strength in the last six to twelve months compared with the market (top 25%) - relative strength doesn't work over short timeframes, such as one month. It excludes the most illiquid stocks, i.e. the bottom 25% of stocks based on market capitalisation. You can read more here.  more »

Benjamin Graham Net Nets Screen

This strategy is one of Ben Graham's most famous bargain stock strategies aiming to find stocks trading for less than their liquidation value.  The idea is to find stocks  trading at such a cheap price that you could buy the whole company and sell off all the assets at a profit with near minimal risk.    It is a simplistic screen which just looks for stocks where the market cap is less than the so called 'Net Net Working Capital'  (defined as  Cash and short-term investments + (75% of accounts receivable) + (50% of inventory) - All Liabilities).  The formula is very conservative in estimating the value of inventory and receivables due to the likelihood that not all will be collectible in a firesale. About such stocks Graham wrote: ‘ No proprietor or majority holder would think of selling what he owned at so ridiculously low a figure…In various ways practically all these bargain issues turned out to be profitable and the average annual result proved much more remunerative than most other investments’. This is not a strategy for the faint-hearted due to the high risk companies that qualify. Graham sought safety from individual bankruptcy risk by diversifying his portfolio with a large numbers of companies – he suggested 30. more »

Neglected Firms Screen

This screen involves seeking out stocks that are covered by few, if any, financial analysts and attempting to discover sources of value that may have been overlooked by other investors. Neglected firms tend to be small, low-profile companies that have not received much media attention. Areas of the market that attract media attention, public interest or sophisticated institutional followings are more likely to be properly priced than areas that are off the beaten track. more »

Piotroski F-Score Price to Earnings Value Screen

The Piotroski F-Score screen aims to identify deep bargain-bucket stocks that are in recovery.  Josef Piotroski, a finance professor, recognized that, while it has long been shown that bargain stocks have strong collective returns, there is very wide individual variability. What he wondered was whether it was possible to weed out the poor performers and identify the winners in advance. He therefore sought to develop a simple accounting-based scoring system for evaluating a stock’s financial strength. Piotroski's F-Score looks at value stocks and tests nine variables from a company’s financial statements. One point is awarded for each test that a stock passes. Piotroski regards any stocks that scored eight or nine points as being the strongest. In this version of the screen, Price to Earnings, rather than Price to Book, is used as the measure of "cheapness".  more »

Jim Slater ZULU Principle Screen

The Zulu Principle is an investment strategy made famous by Jim Slater in the book of the same name. It is a GARP investing style which uses a combination of growth and value, looking for shares where brokers are forecasting high earnings growth, but which are currently valued at a price that is low relative to their forecast earnings. The strategy aims to capture growth companies at a reasonable price by using the PEG Ratio. Slater uses forecast earnings to calculate both PER and the EPS Growth Rate. As Slater puts it: "I have always been attracted to growth shares, particularly those that can be purchased at what I perceive to be a discount to their proper value”.  more »

R&D Breakthroughs Screen

This screen seeks to identify research-led businesses that are investing significantly in future development in order to try to identify their potential future growth before the market does.  As Jack Hough notes, "When a company announces a breakthrough drug or a sudden advance in computer-chip technology, its shares often soar right away. Imagine being able to foresee which companies are due for such lucrative discoveries". Specifcially, the screen looks for R&D investment levels that are increasing and which equal at least 5% of annual sales and 5% of total assets. It also looks for Price to R&D ratios that are below 20x. more »

Bold Earnings Revisions Screen

This screen seeks to identify stocks that have experienced recent revisions in the earnings estimates. Specifically, it looks for stocks that have seen one analyst revision in the last week/month, to try to see if there is an analyst moving away from the consensus. This follows research that showed "bold" estimates like this have a significant impact on share price performance. Note: that this screen on its own isn't able to only pull back revisions that are "bold" (moving away from the consensus), as opposed to revisions that are "herding" (moving closer to the consensus). This will need to be done by analysing the actual list of companies produced in more detail. more »

Bill Miller Contrarian Value Screen

This screen seeks to emulate the style of Bill Miller, manager of Legg Mason Value Trust. Miller’s strategy focuses on identifying securities that are trading below their intrinsic value, but differs from many value managers in that he focuses on cash earnings, not accounting earnings. He looks for firms that may be undervalued based on the present value of future cashflows, although this is not easy to screen for in detail. He says: "Ideally, what we want is a company... that has tremendous long-term economics and those economics are either currently obscured by macroeconomic factors, industry factors, company-specific factors, or just the immaturity of the business." Diversification is a crucial element in Miller’s strategy but he aims for diversification among the stocks it incorporates, rather than the sheer quantity. By focusing on companies that are being shunned by the market, this strategy takes on higher risks in hope of higher returns. The value moniker for his Fund is perhaps misleading because Miller has bought many Internet “growth” stocks. You can read more about Miller's approach here. more »

Earnings Downgrade Momentum Screen

This is a strategy that aims to zero in on stocks where brokers are downgrading their earnings estimates.  In theory, this is a short-selling strategy! The idea is that brokers have a behavioural bias which anchors their new estimates too closely to their previous estimates thus making a high likelihood that earnings estimates will continue to fall in future. Continuing earnings estimate downgrades can be negative for stock prices.   However, research has shown that investing on the basis of broker recommendations does not generally work because of the bias in those recommendations. Research suggests that focusing on positive recent changes in broker recommendations may be more fruitful, particularly in combination with other signals, although this doesn't appear to be true for downgrades. You can read more here.  more »

Earnings Upgrade Momentum Screen

A momentum screen based on buying stocks with rising analyst earnings estimate revisions in light of empirical findings that stocks with their estimates revised often outperform the market over at least the next 12 months. Although investing on the basis of broker recommendations alone does not appear to be a successful strategy because of the bias in those recommendations, research suggests that focusing on recent changes in broker recommendations is more fruitful, particularly in combination with other signals.

Altman Z-Score Screen

This is a short-selling strategy based on the Altman Z-score which combines five weighted business ratios to estimate the likelihood of financial distress. The idea is that, if the Altman Z-Score is close to or below 3, it is wise to do some serious due diligence. The Z-score results usually have the following "Zones" of interpretation: any Z-Score above 2.99 is considered to be a safe company. Anything below 1.80 is in the distress zone, with a strong likelihood of the company going bankrupt within the next two years, while anything between 1.80 and 2.99 is in a "grey zone". In line with Altman's result, this work is based on last annual reported results and does not factor any interim updates. According to the research, the Altman score does experience false positives (i.e. classifying the firm as bankrupt when it does not go bankrupt) in approximately 15-20% of cases. more »

Geraldine Weiss Lite Dividend Screen

A blue-chip focused screen focused on buying blue-chip stocks whose dividend yields are near the high of their historical ranges and selling when the dividend yield declines to historic lows. Geraldine Weiss was the founding editor of Investment Quality Trends - one of the longest-lived investment newsletters.  According to a 2002 Forbes article,  she has seven criteria in total (but the last criteria comprises a further six "blue-chips only" conditions). A stock: 1. Must be undervalued as measured by its dividend yield on a historical basis. 2. Must be a growth stock that has raised dividends at a compound annual rate of at least 10% over the past 12 years. 3. Is selling for two times book value or less. 4. Has a P/E ratio of 20-to-1 or below. 5. Has a dividend payout ratio in the 50% area (or less) to ensure dividend safety with room for growth. 6. Debt is 50% or less of total capitalization. 7. Meets all six of our Blue Chip Criteria: dividend raised five times in the last 12 years, carries an A rating from S&P, has at least 5 million shares outstanding, at least 80 institutional investors hold the stock, 25 uninterrupted years of dividends and earnings improvements in seven of the last 12 years. While it’s difficult to replicate this screen exactly for the UK market, we’ve produced a Geraldine Weiss-lite version along similar lines.  more »

Earnings Surprise Screen

When companies report earnings significantly higher than analyst's earnings estimates the result is known as an 'earning's suprise'.  While earnings surprises often create spikes in the share price on the day of the announcement, they have also been observed to trigger longer term increases in the share price.  This effect is known as the  "Post Earnings Announcement Drift" and can last for several weeks or even months after the announcement date.  The effect is generally attributed to the fact that analysts are slow to revise their forecasts and the market does not fully react to the information about future growth conveyed by the earnings surprises.  The idea behind the strategy is to buy stocks that report earnings surprises and hold them over this time period. Positive surprises often happen at the beginning of a turnaround, or a new growth cycle where sales start to accelerate beyond the historical rates, “surprising” the analyst community.  You can read more here. more »

James Montier 'Unholy Trinity' Screen

This is a three point short selling screen based on the approach outlined by James Montier in 2008 to identify potential candidates in weak markets.   1. High Valuation (Price to Sales Ratio > 1) - Calling the Price to Sales ratio 'insane' as a valuation measure due to its lack of focus on profitability,  Montier first screened for companies trading at a multiple of at least 4 times sales. 2. Weak Fundamentals  (F Score < 4) -  With the valuation side covered, he then qualified this list by screening for the financially weak companies having a Piotroski F Score of 3 or less.  3. Poor Capital Discipline (Asset Growth > 10%) -  But unsatisfied with only focusing on high valuation and weak fundamentals, Montier also showed that company executives were often wasteful capital allocators; research showing that companies with low asset growth rates highly outperform companies with high asset growth rates by 13% annually.  more »
