3 Outline Introduction Why Screening is Necessary What Constitutes a Good Screen? Sources of Information Screening Processes Examples of Commercial Screens

4 Introduction Security screening involves reducing the security universe down to a manageable size Picking stocks is an art rather than a science  There is no single best way to choose individual investments

5 Why Screening Is Necessary Time Constraints Everyday Examples of Screens

6 Time Constraints The NYSE and AMEX, and Nasdaq list thousands of potential investments  There is no time to analyze every security and process the associated information Many people never develop a well- conceived way to deal with the information overload

7 Everyday Examples of Screens University Admission Test The Football Team

8 University Admission Tests More people apply for admission than are ultimately admitted Universities use two steps:  An initial screen  Closer individual scrutiny for those passing the first round

9 The Football Team More players try to join the football team than the rosters can carry Coaches may use screens:  40-yard dashes for running backs  Bench presses for offensive linemen

10 What Constitutes A Good Screen? Ease of Administration Relevance and Appropriateness Acceptance by the User Ordinal Ranking of Screening Criteria

11 Ease of Administration The screen should be easy to administer and implement e.g., narrow stocks down to thinly traded stocks by using The Wall Street Journal  Thin trading refers to a security with a relatively small number of shareholders and a lack of trading volume

12 Relevance and Appropriateness Screens should logically have something to do with the ultimate objective For example, start at the top of the NYSE listings with your screen

13 Acceptance By the User Screens lose value if people fundamentally disagree with it For example, people may not believe in SAT scores as a screen for admission

14 Ordinal Ranking of Screening Criteria Use a screen pecking order for multiple- stage screening:  The first screen is the one that eliminates the most alternatives  The second screen eliminates the next highest number of alternatives, etc.

30 Screening Processes Multiple-Stage Screening Subjective Screening Screening with the Popular Press Only A Quick Risk Assessment Screen with the Stock Report

31 Multiple-Stage Screening Most investment applications require several screening stages  e.g., earnings per share by itself is not very useful  e.g., in choosing a growth stock, it would not make sense to search initially for those with the highest dividend yield

32 Subjective Screening Not all screens need to be quantitative For example, socially responsible investing:  Tobacco stocks, nuclear power, animal testing, the environment, human rights, etc.  Best of class investing recognizes that all firms can be faulted in some way and looks for “role models” within each industry

33 Screening with the Popular Press Only Price/Earnings Ratio Dividend Yield Stock Price Exchange Listing Familiarity 52-Week Trading Range Options Availability

34 Price/Earnings Ratio Low PEs are good:  Investors pay little to get a lot High PEs are good:  The efficient marketplace anticipates that future earnings will be higher than those of the past

35 Dividend Yield Dividends do not materially alter a recipient’s wealth People like to receive dividends:  Strokes the ego  Important for income or growth of income objectives

36 Stock Price Some people believe in an optimum trading range for stock prices The cost of a share should be merely a market People prefer to avoid odd lots  e.g., investing $2,000 means the stock price cannot be higher than $20

37 Exchange Listing Some clients may want to restrict their investments to a particular exchange:  AMEX  NYSE  Nasdaq

38 Familiarity Invest in companies that you know something about Familiarity is a subjective criterion

39 52-Week Trading Range “The stock is trading at the low end of its annual high and low” If the market is efficient, annual highs and lows are of no value in predicting future prices

40 Options Availability Some people invest in equity issues that have options available because they are versatile Options information is contained in the financial press

41 A Simple Financial Pages Stock Screen

42 A Quick Risk Assessment Screen with the Stock Report ROA and ROE Evaluating ROA and ROE

43 ROA and ROE The Stock Report contains ten-year histories of ROA and ROE:  Useful for a quick comparison of companies: ROA is net income after taxes divided by total assets ROE is net income after taxes divided by equity If the firm has debt and positive earnings, ROE will exceed ROA

44 Evaluating ROA and ROE A “good, safe investment” has a history of stable ROA and ROE figures, with ROE somewhat higher than ROA If ROE is substantially higher than ROA, the firm is heavily leveraged (risky)

45 Examples of Commercial Screens Published Paper Data Computerized Data
