Before buying a security, you should systematically look at its PER, to know if the purchase price is overvalued or not, so is it really necessary to always calculate the TMC / NBI because this gives a more global vision of the market?
I'm not sure I understand why you have to evaluate the market before making any purchase and what the consequences are if you buy shares when the market is significantly overvalued. Could you clarify this for me?
Why do you say that the market is going to crash for sure in a short time? Similarly, seeing that you are approaching the real estate sector, do you have financial structures to pay less tax each year? (Ex: holding structure with mother-daughter regime….)
