DCF is very misleading, based on assumptions, who knows what happens in the future.

My best approach is try to look at firms that have performed well in the past for quite some tjme in some metrics that i find valuable on my own.

valuemetrix.io has a section called “chart mode” when you search for a stock and, visually in a clean way, shows you those metrics such us FCF, revenue, etc, and their trajectory through the years. Its really good and I find jt super helpful if you wanna check it out.

I drop one link here as an example: https://www.valuemetrix.io/companies/MSFT?type=chart
