We added 12 months minus 1 month (12-1 month) momentum to the Quant Investing stock screener.
How it is calculated
In the screener we call momentum Price Index and this is how it is calculated: Price Index 12m Minus 1m = Share price 1 month ago / Share price 12 months ago.
For example
Assume the current date is 1 October 2016.
Price Index 12m Minus 1m = Share price on 1 September 2016 / Share price on 1 October 2015.
The ratio shows you the return of a share price over the past year but excluding the last month.
This lets you screen out companies with a large jump in share price over the past month which studies have shown usually reverses shortly thereafter.
How to interpret results
A Price Index 12m Minus 1m value greater than 1 shows that there's been a price increase over the period whereas a value less than one shows that there has been a price decrease.
