Any idea why the companies on your Piotroski screen differ so much from those on the AAII screen?  The only overlapping company is HAST (which is their only company with a Piotroski score of 9).

 

Probably because the AAII screen has other criteria in addition to the Piotroski factors:

  • The price-to-book ratio ranks in the lowest 20% of the entire Stock Investor database
     

  • The stock does not trade on the over-the-counter exchange

I haven't had a long exposure to AAII so I can't say anything with confidence.

But a screen will always produce different results. I'm sure a simple PE screen also produces different results between Yahoo, Google, MSN and others.

My screens are also customized so I include my some of my own metrics and ideas into it.

Hi Jae,

Thanks for creating these screens.  Any idea why the companies on your Piotroski screen differ so much from those on the AAII screen?  The only overlapping company is HAST (which is their only company with a Piotroski score of 9).

Thanks.

Altman Z and Piotroski Screen

I've included two new additional screeners by popular demand.

The Altman Z screener and Piotroski screen.

Both screens will help you to weed out the companies with unhealthy balance sheets or operations.

You can find value and growth potential in cheap stocks, but there aren't many quality stocks in the cheap stocks pile.

A free spreadsheet to calculate the Altman Z score and Piotroski score is also available.

You can read about and download the spreadsheet in the following links.
