equity theme and spreads

Hi all,

I've been trading using purely technicals for slightly more than a year and now i'm starting to incorporate equity themes and fundamentals on a longer time horizon.

Can anyone share with me eg i have a fundamental idea from the ISM, whatever economic indicator. and i decide on a sector to l/s.

I'm interested to know how to choose a winning and losing counter of that lot.
can guys here share with me how will you do your:
1. value chain analysis
2. forecast ratio analysis

to determine the best and worst? Thank you!

Also how do you fundamental guys determine an upcoming equity theme.
