This was actually applied yesterday. Should be locking based on the default action score now.
Found the bug and squashed it.
Looks like an intermittent issue.
Here's an article last year on this very question.
Why does the Action Scores fluctuate wildly? and is this volatility an error in the system?
Given the information you have at hand, I would raise the same questions.
So let me zoom out to give you the fuller picture to help you better understand the various reasons why this occurs and what affects the Action Score.
To quickly review, here are the data points that make up the Action Score. I discussed how the Action is created in an earlier email.
E.g. PRKA had a Piotroski Score of 5 in 2014, but then jumped to an 8 in 2015.Same rule applies to quarterly periods.
If a stock had a high Piotroski score of 8 but then fell to a 5 in the latest reported quarter, the Action Score will drop as a result because the Piotroski Score is importantfor Q,V and G.
The quickest way a stock will rise or drop in rank is if the Piotroski Score changes in a big way.
During my tests and studies, I wanted to leverage a proven system. I'm not interested in reinventing the wheel. The Piotroski Score has been studied and tested extensively which is why I wanted to use it.
By not having the Piotroski Score as the first line of defense, too many stocks rocketed to the top 10 because of a single crazy number.A stock like GRSU with a CROIC 4,366.9% would squat high on the list.
By awarding stocks with Piotroski Scores in the optimal range of 7-9 and penalizing stocks with low Piotroski Scores (1-4), I'm able to pass stocks down the funnel that meet accounting and quality standards before the rest of the calculations for Q,V and G are processed.
And you also see that Value includes 2 metrics with high weightings that rely on price. If the market is volatile, the value score is the first one to adjust, which again causes jumps as we update our scores daily. Not weekly or monthly like many other sites that rank stocks.
If I hide stocks that don't meet certain industry or metrics, you'll have a cleaner and shorter list for sure with less volatility.But to give you more control, I'm dumping the entire database of stocks for now.
The Action Score is also not suited for financial stocks like banks, insurance, REIT's. That's something I want to improve down the road. Therefore, these financial stocks also tend to stir the waters depending on market conditions.
Once the screener is built out and you have control over which stocks should or shouldn't be displayed, you'll realize that it's more "consistent" :)
Hope that gives you a better background and understanding of the backstory and theory behind how the Action Score is graded and ranked.
What stock is this again?
Are you seeing it from the key stats or screener?
The numbers look like this.https://www.screencast.com/t/cVuoXTIV4Pn
I've noticed this as well and we are working on finding the bug.
Here's a screenshot.
If you go to OSV Ratings and then look at the explanations on the right, you'll see the range that we use.
Thanks for bringing this up.
Although not a checkbox, I've made some quick changes to eliminate auto sorting.
I've updated it so that it is only sorting in alphabetical order, but will update it next time so that it only sorts based on Action Score. This way, the positions will stay locked.
Are you referring to the financial statements?
If you click on %, you'll see that it is a percentage of revenue.
