Piotroski Enhanced Value Stock Selections - January

by: JD Henning


Publishing five of the 15 Piotroski Enhanced Value Stock Selections available to January subscribers only.

Latest update of Enhanced Piotroski Portfolio returns for all portfolios YTD. Best return to date: September Portfolio +10.35% (four months).

Value stock selections will likely return to greater favor as record momentum and high market valuations lead to sharp corrections.

Piotroski model remains the top performing value model in financial research and as tracked by the American Association of Individual Investors with 22.9% annualized returns over 16 years.

Four out of five of the Enhanced Piotroski Value portfolios are each currently outperforming the AAII Piotroski High F-Score portfolio for all of 2017.

Piotroski Value Portfolio YTD Returns


This article continues the series of testing the best value investment research over a one-year time horizon for well documented and substantial value investing returns. The January Enhanced Piotroski portfolio represents the sixth portfolio and last test portfolio of the Piotroski F-score model until the annual portfolio replenishment occurs again in August. This study is testing the Piotroski F-score model to see how many of the different value portfolios formed each month can outperform the market over a year long period.

So far the September, October and December Portfolios are each beating the S&P 500 in their respective time periods. Additionally, four of five Enhanced Piotroksi portfolios are significantly outperforming the AAII 2017 Piotroski High F-score portfolio that has a 3.0% return through 12 months.

These Piotroski value selections were designed as a more stable, annual investment approach that differs greatly from the Weekly Breakout Forecast based on highly volatile, short-term momentum stocks. The value selection formulas have been well documented over the past 17 years to consistently outperform. As the chart below illustrates, the average portfolio is returning 1.95% per month YTD with a strong emphasis on fundamental growth characteristics.

  • The January stock selections build on the findings from the Amor-Tapia & Tascon (2016) research that evaluates top selection models in more detail in the initial August report that found the Piotroski model to be one of the best models tested for value investment selections.
  • The American Association of Individual Investors also documents their own multi-year test results of the Piotroski F-score as one of the best performing models with annualized total returns of 22.8% from among dozens of selection models that they monitor.
  • The Enhanced Piotroski portfolios offered here are outperforming the AAII Piotroski portfolio for all monthly test portfolios except November. The selections are well on track to outperform the S&P 500 and other comparable value portfolios.
  • Selection portfolio details since September when this research became subscription based are available to subscribers only.

Background on Value Scoring Systems

Calculating scores and assigning values to stocks based on fundamental data remains one of the most popular methods for value stock investing. Most of us are familiar with such scoring systems as the Value Line Rank (started in 1965), the CANSLIM composite ranking system (started in 1988), the Zacks Rank (started in 1982, first made public in 1992) and many other popular systems that have given us good results over the years. To this day it is not uncommon to find substantial overlap among the best stocks identified by different value ranking methodologies. Most medium to long-term investors are well served by taking these models into consideration.

Less well known are the academic composite value models based on fundamentals that continue to be rigorously tested in peer-reviewed financial literature. Some of these published models have their measurement scoring integrated into publicly available stock screens from various stock analysis websites. One of the best academic models retested recently by Amor-Tapia and Tascon (2016) is the Piotroski score model created by Joseph Piotroski in 2000:

The Piotroski (2000) FSCORE: The Score consists of aggregating nine individual binary signals derived from accounting variables related to profitability. The most favorable value score is 9 and the least favorable is zero. (Amor-Tapia &Tascon, 2016)


The Piotroski F-Score model has been well documented in the financial literature and by practitioners to generate significant abnormal returns on an annual basis. Over the past 15 years it remains one of the top selection models among dozens tracked by the American Association of Individual Investors. The enhanced model produced here each month further eliminates financial outliers and low-priced stocks that may jeopardize the best performance results possible. As always, I trust this will be a profitable contribution to your investment objectives!
