Combining Value and Momentum
by John Bajkowski
Kevin Truitt illustrates how investors can benefit by combining traditional value and price momentum filters in his July 2013 AAII Journal article “Investing’s Odd Couple: Value and Momentum.” Research cited by Truitt highlights fundamental and technical factors that can be combined to help avoid both value traps and overvalued momentum stocks. It is possible to combine growth and value approaches with good track records into a combined approach with high expected return, but even lower expected volatility. Growth and value approaches tend to shine in different market environments, providing diversification benefits.
This issue’s First Cut applies the key factors highlighted in the article using AAII’s stock screening and fundamental database, Stock Investor Pro.
The starting universe of 4,953 stocks consisted of exchange-listed companies. The First Cut first looked for companies with price-earnings ratios (price divided by trailing 12-month earnings per share) lower than the median industry ratio in which the company is classified. This type of relative comparison adjusts automatically to industry prospects and overall market conditions. The First Cut then filtered for companies with a PEG ratio (price-earnings ratio divided by five-year historical growth rate) to be either below the industry median or below 1.0. The screen’s final fundamental test required that the ratio of enterprise value to EBITDA (earnings before interest, taxes, depreciation and amortization) be 10 or smaller. Enterprise value is calculated by adding market capitalization, preferred stock and total debt, and reducing this sum by the amount of cash held by the firm. The enterprise value to EBITDA ratio relates a firm’s takeover cost to its earnings potential. The lower the ratio, the more attractive the firm. A total of 362 exchange-listed stocks passed all of the value filters.

At one point weren't the actual SIP statements for the screen included with the online version of the article? When trying to duplicate a screen from its literal description, slight variations in interpretation can result in big differences in the final screen statement. It would help enormously if we could see the screen as the actual statements in the screen editor.

Did an exact duplicate of the screen and came up with 13 entirely different companies. There was not a single match. My data was as of July 5th while the article used June 14th data. If there is that kind of shift in just 3 weeks, this can't be a very reliable screen. Comments?

The market sentiment shifted rather dramatically over the last month. This First Cut makes use of short-term price momentum and will likely have more significant changes n passing companies than other screens.

Hi John,
Two very interesting articles here. Will this screen be added to the other screens, or will it just be available through Investor Pro? I would somehow like to see a history. Thanks!--C.J.

Can statistics be provided on 3, 5 and 10 year historical returns using the approach, along with volatility? I like the screen, but would like to compare results to some of the tried & true screens I already use.
Thanks, KS

Hi Kevin,
This screen has not been backtested, so the data you seek is not available.

Will the First Cut value and momentum stocks go into your shadow portfolio? Is there a surrogate First Cut portfolio that gets updated?

As an old FORTRAN programmer I'm not familiar with the IIF Boolean. I used IF etc.in the old days. Is there someplace in SIPro where these operators are listed? Also,is there a ranking for the custom fields? That is, don't they have to appear at the start of the program you have written above? Finally, do we just copy your language into the operator column and hit "run".

John Wiley -
Use the Custom Field Editor in SI Pro to create the three custom fields shown here. Copy the custom field name in the Name box and copy the line of "code" into the Expression box. Once you've created and saved the custom fields, use the Screen Editor to build the screen, plugging in the custom fields where shown. You'll choose the operators you need in the Screen Editor from a drop-down list when you click on the operator field.

John Wiley- Sometime around 2008 SIPRO changed the way "zero" values are handled. The change was to NA or NULL. I.M.O. a terrible change for writing code. The change can cause problems with custom fields unless cumbersome allowances are made. My original custom fields were essentially invalidated. I canceled my SSI-PRO subscription. IsFieldNull and In-Line If (IIF). See May 2008 Stock Investor News.

Can someone explain why momentum is the right filter to use? My impression was that you wanted to buy stocks when they are beaten down not when they are rising.
