AAII’s purpose is to provide investment education and information. Our ongoing goal is to prepare individual investors to effectively manage their investments and to provide the necessary education, data and support to help them in that effort.

Over the years, however, we became increasingly aware that many of our members wanted more specific help. In talks with members, we found that there is a need for an intermediate level of support—not a complete advisory letter, but some specific guidance for individuals in developing an effective investment program—a real-world example of how to take an investment approach and construct and monitor an actual portfolio. AAII addresses this need by currently offering our members access to our Model Shadow Stock Portfolio.

This brief guide is offered as a starting point for those members interested in following the investment direction and education we offer through the AAII model portfolio. The performance of this real-world portfolio has been impressive, but please be advised that a bit of study and commitment is required of members seeking to follow our portfolio.

AAII Model Shadow Stock Portfolio

The Model Shadow Stock Portfolio provides guidance for investing in the promising micro-cap value sector of the market. The portfolio was initially conceived to show the membership of AAII how to capitalize on the most promising academic research to manage a stock portfolio without having to commit a great deal of time and effort to day-to-day monitoring. In fact, AAII manages this real-money stock portfolio (it is not a hypothetical portfolio) by simply reviewing holdings on a quarterly basis.

The Model Shadow Stock Portfolio reflects the following beliefs:

A True Do-It-Yourself Model


To pick the right stocks for AAII’s Model Shadow Stock Portfolio, we focus primarily on portfolio formation and risk reduction. The stocks in the AAII Model Shadow Stock Portfolio are largely risky stocks when evaluated separately. But when taken together as a portfolio, most of that individual stock risk has been diversified away. In fact, the average risk of the individual stocks has been reduced by about 70%. The central point of our Model Shadow Stock Portfolio is that the risk of any individual stock is not important if your portfolio is well diversified. What is important is how the addition of that stock affects the risk of your overall portfolio. If you are not following our full portfolio but instead use our list of stocks as a tool to generate investment ideas, we suggest that you adhere to our overall strategy by selecting and monitoring a portfolio that consists of at least 10 stocks. Choosing stocks in different sectors will provide added diversification and protect your portfolio from some sector volatility. Furthermore, be sure to consider fees when making your investments. While there is no recommended minimum, investments should be large enough so that fees are insignificant.

While the Model Shadow Stock Portfolio minimizes risk, it is still prudent to take into account your personal risk tolerance. Investors are rightly worried about the amount they invest in a micro-cap strategy. Even a properly diversified micro-cap portfolio will be more volatile than the total market because these stocks are inherently more risky. The worst time to sell a stock is at the bottom, so be sure not to put so much weight into your micro-cap portfolio that you cannot stomach the losses. Keep in mind that due to the nature of the Model Shadow Stock Portfolio, it will offer very little income in the form of dividends.

Two Ways to Build Your Own Shadow Stock Portfolio


Follow the guidance provided here and issued in the AAII Model Portfolios columns in the January, April, July and October AAII Journals—remember, this portfolio was designed to require only simple modifications on a quarterly basis when company fundamentals change.

Utilize the resources we offer at www.aaii.com/stockportfolio where we provide monthly updates on the “Passing Companies.” The Passing Companies list shows the companies that meet the criteria for the Shadow Stock screen on the “data as of” date. This list is not to be confused with the Actual Portfolio list, which shows the companies that AAII currently holds in our Model Shadow Stock Portfolio. We run this screen monthly, so please click here for the most current list of stocks.

Ongoing Management of Your Stock Portfolio


AAII’s Model Shadow Stock Portfolio is not intended to be an advisory service in the usual sense of that term—it is not intended to be a list of individual stock recommendations. Instead, the model portfolio serves to show you how to use a value-oriented approach to select micro-cap stocks in an effort to build your own Shadow Stock Portfolio. Profitable micro-cap investing requires extra care. The portfolio construction and monitoring rules were developed over the years to minimize real-world costs and maximize profits.

In the pages of the AAII Journal, we provide quarterly commentary on the Model Shadow Stock Portfolio (ours has been running for 20 years) and provide suggestions on how you can vary our approach to build a portfolio suitable for your own specific needs. At www.aaii.com/stockportfolio, we present the detailed rules for building and managing a Shadow Stock Portfolio as well as a monthly list of stocks that meet the criteria for inclusion.

Ongoing performance of AAII’s Model Shadow Stock Portfolio is tracked online, but keep in mind that a portfolio can be built by simply following the investment moves outlined in the AAII Model Shadow Stock Portfolio columns found quarterly in the AAII Journal.

Stock Portfolio Management Criteria

It is our belief that a quarterly review of the following purchase, sale and management criteria is all that is needed to build your own Shadow Stock Portfolio. Simply review your holdings on a quarterly basis to see if any fundamental changes make them candidates for sale (see sell rules below). If you have new investment funds available or cash from sales, you can look at the list of Passing Companies (www.aaii.com/stockportfolio) to see if any companies meet your needs for inclusion in your Shadow Stock Portfolio.

Stock purchases must meet these criteria:

    *These figures will change gradually as market values change. Any changes will be noted in the AAII Journal and online.

Stocks are sold if any of the following occur:

In summary, we sell when the market recognizes the value of one of our holdings, thus driving up the price so that it no longer remains in the “shadows” of Wall Street.
