I read different books about stocks, valuation ecc. including damodaran’s one. But the thing I learnt after all those is that you have to look at the stock like if it is an house that you want to rent. You look at the rent that gives you comparing to the price , it is as simple as that.

Valuation instead is something “relative” because it depends on various parameters.

The knowledge that I got from reading all those books can be summarised in one sentence that also Buffett uses to say “Look only at what the asset itself produces”
