Stock Screening

Might stock screening prove the key to your investment success?

I read Jack Hough’s new book Your Next Great Stockon the plane ride back from Chicago. I enjoyed the book, and he did a good job of presenting a very basic introduction to stock screening. He reviews the screeners on the market as well as some of the academic evidence supporting factor based research. Jack didn’t present much in the way of backested results or sample portfolios, which is unfortunate. (I prefer factor based stock models that score all stocks on a scale of 0-100 based on composite factor rankings – like Portfolio123 – rather than screens that simply update at fixed time intervals – like AAII or ValueLine.) Most institutional pm’s use Factset, ModelStation, or something similar and expensive.

A nice free screener is James Gritton’s backtest.org. It uses the historical ValueLine database (~2000 stocks with mkt caps over $400 million) back to the late 1980s. You can put together all sorts of screens, combinations of screens, etc. (For more information check out the Mechanical Investing board at the Motley Fool.)

Here is a simple screen of screens with impressive historical results of 30% annual gains with S&P like vol. (The logic for the screens is at the bottom of the post). There is even a free software app that can find the current picks for you called Saucer.
