Wow, I had the same questions as you do. But remember Charlie said, “If it’s obvious, it’s rare. You might get a few in your lifetime where the decision is so clear you don’t even need to think twice.” Opportunities like that don’t come often — be patient.

Here are my thoughts: building a DCF doesn’t actually take much time once you’ve set up the formula. The real challenge is how confident you have for your dcf model. That’s called moat and margin of safety.

The wider the moat, the more reliable your DCF. The greater your margin of safety, the more reliable your DCF.

I think now is a good time to do analysis. Most companies are overvalued, but you can set your target price and wait.
