Hi Rick, Here's what I did. I selected the field for Stock Price Stability then put in the "Maximum" field 30 and did the screen. It brought up about 550 possibilities.
Here's the results:
S.P.S. # of Companies 30% 550 25% 467 20% 384
Next I added a second qualifier of Stock Price < $10 per share with a 20% SPS rank. This further dropped the potential list to 150 stocks.
So, the screener is working. I can't guess why you're not getting results.
I like this ranking because it doesn't care if the stock in question is positively or negatively correlated with the general market. Sometimes we find some gems in the negatively correlated side that would never show up if we'd been searching for High BETA only.
