COMPUTER SCREENING - A USEFUL FIRST STEP
IN THE STOCK SELECTION PROCESS
by LARRY

In all the world's exchanges, there are tens of thousands of separate common stocks. In India alone, for instance, over 6000 issues are listed on their main exchange. How might you select, among the blizzard of company shares, just the ones you would like to purchase?

Fortunately, most actively traded, and so fairly liquid, stocks are able to be screened online, and/or through frequently updated CD services, via the computer.

You may thus, in a matter of minutes, set up your desired parameters, apply them to this smaller universe of available stocks, and so winnow the field down from many thousands to a more manageable few dozen or so different issues. These, in turn, may be further filtered with more refined criteria, all while you sit at home in leisure.



There are any number of ways to screen for desired equities. For a modest membership fee of $29 a year, one can gain access to a multitude of stock screens developed by the American Association of Individual Investors (AAII). The most profitable of these, according to "Smart Money," since 1997 have performed at stunning appreciation levels, with annualized gains of over 30 or even 40%. Such returns, however, do not take into account commissions, bid and asked price spreads, or the taxes on frequent trades that could be required for following all the screen selection changes.

Another sterling record is that of value investor or contrarian Al Frank whose Prudent Speculator recommendations have provided 19-20% compound annualized total returns over both the last ten and twenty years. Mr. Frank, according to his book, The Prudent Speculator - Al Frank on Investing, emphasizes a variety of low price to value standards, as well as low company debt and relatively high return on equity, in his selection criteria.

As I prefer an approach somewhat similar to Al Frank's (though I do not claim to capture his recommendations' excellent returns), I'll show the stock selection use of the computer by giving an illustration of fairly typical value criteria.



First, find yourself a good stock screening site. I like T. Rowe Price and Charles Schwab for this, but there are many from which to choose.

Next, put in your screening criteria and use them to reduce the thousands of available assets to only a few score.

Here, for example, is one initial set of generic value parameters:

  • Return on equity (ROE) 15% or more;
  • Debt to equity 1 or less;
  • Price to earnings ratio less than 10;
  • Price to book value 2 or less;
  • Price to sales (revenue) 1 or less;
  • Price to cash flow ratio 5 or less.

Applying those guidelines reduces a selection pool of about 6000 stocks to only 69 (per the Schwab screening tool effective at the close of business 8/17/04).

I screen the results further by culling from those selected stocks the ones with the lowest debt to equity and price to sales ratios. Today these turn out to be stocks with D/E .33 or below plus P/S .5 or below.

35 stocks remain after applying those two filters.

I distrust the accuracy of any single stock selection tool and so examine these 35 stocks still more by looking them up on AAII's site and both double-checking and further refining the criteria.

Here, for instance, I also look for which stocks do or do not pay dividends, check the payout ratios (must be .5 or less), see if their current ratios are 2 or above (a plus, but not essential), note the market capitalization (generally, lower is better), and consider the latest stock prices (preferring not to purchase very low or very high priced stocks, with a few exceptions).



I am left with a couple dozen potential buy candidates with, overall, low market capitalization, high profitability, low price to value ratios, and low debt.

Finally, I use two or three online stock rating services (such as Quicken, Value Line, and Charles Schwab) to see if any of my remaining selections are highly ranked and, if so, why, and to note any recent news on the handful of stocks left for which rating service interest has now been found.



There is no guarantee the remaining two or three stocks will do well in the marketplace, but at least for the patient investor they would seem to have a better than average potential for good appreciation.

A thorough investor will not stop his or her analysis at this point but would take it as only a first step.

Other avenues of research might include review of a stock's info in the monthly "Standard and Poors Stock Guide," a check of the stock's report (if available) in "Value Line," reading analysts' assessments of the stock, studying the company's SEC filings, latest annual report, and recent quarterly reports, and going to a financial chat room, such as the comprehensive "Discussion Boards" available for a modest annual fee through The Motley Fool, to see what others may be saying about the value and prospects of the companies and their stocks which still have highest appeal for addition to your portfolio.



Based on our illustration selection process, the following stocks currently seem attractive:

First American Financial Corp. (FAF) (recent price $28.06)
Stewart Information Svc. (STC) (recent price $34.85)
Maxcor Financial Group, Inc. (MAXF) (recent price $9.36)
