How do valuebuddies do their homework?

[BaconFTW]

Hi all! I'm new here and am just embarking on my investing journey

For me, i try to look at a company's fcf. But i'm not sure if this is applicable to all sectors/industries. E.g telcos here will prob have less assets (hence less working capital) than say an airline.

Then i check the usual ratios - p/b, p/e, div yields.

Any advice if im on the right track? Thks mucho!
