Need Opinion - Due to the constant influx of new money into the market due to finance influencers etc... will the monetary value of ETFs, Stocks etc. inflate compared to the actual value of the companies behind those finance products?

Hi,

this is not really related to Daytrading but I have a general question related to the overall financial market especially in Europe. Maybe it applies to US as well.

In Europe you have every day some new social media influencer hyping investing into stocks and ETFs so you can retire early with 10% grow per year blablabla

So the more people see it. the more they pump fresh money into the market and value grows of the financial products.

But this means there is a disconnect between the actual value of the companies and the price of the ETFs, Stocks etc?
