Confused in equity segmentation

Hey guys I am confused in equity segmentation. I know it’s supposed to be a simple concept but I just wanted to confirm if my understanding is correct.

I am assuming that if a company is investing in emerging countries and if they are investing in stocks that are having high growth with low PE multiples, this would mean that they have segmented their universe by style and geography.

All they have to do now is segment by product and size. Is this correct??

Or is there something I am missing out on.
