Why can't most analysts' words make the audience profitable?

This is determined by the relationship between supply and demand.

Most market participants are actually unwilling to listen to the content that can really make money.

What everyone wants to hear is just the reinforcement of their own views.

For example, if I am bullish and do more, I hope to find a firm bullish view in the market and like it to gain recognition.

If he is wrong, I think he is stupid; if he is right, I think I am great.

Since the demand is like this, the supply cannot be blamed.

The market is naturally full of noise. No matter how organized an analysis looks, it is essentially just supply for demand and cannot help you make money.
