OPM Sole Criteria for Stock Selection – Screener.in

I was working on below filter criteria in Screener.in ( OPM – Sole Criteria – Screener )
**OPM last year > OPM preceding year AND
OPM preceding year > OPM 5Year **

Given below are the results:

Can an Improving OPM be treated as Sole Criteria for stock selection? Average Stock returns are very much impressive for basket of stocks selected on above criteria.

I have tried different filter criteria but they return returns below returns delivered by above filter criteria.

Other filter criteria that I have considered

ROCE & ROE based:

Return on capital employed > Average return on capital employed 3Years AND
Average return on capital employed 3Years > Average return on capital employed 5Years AND
Return on equity > Average return on equity 3Years AND
Average return on equity 3Years > Average return on equity 5Years

Operating Cash flow based:

( Operating cash flow 3years / 3 ) > ( Operating cash flow 5years / 5 ) AND
( Operating cash flow 5years / 5 ) > ( Operating cash flow 7years / 7 ) AND
( Operating cash flow 7years / 7 ) > ( Operating cash flow 10years / 10 )

EPS based:

EPS last year > EPS preceding year AND
( EPS last year / EPS preceding year ) > EPS growth 3Years
