You're thinking too sensible for the market. If everything was priced at "what it's worth" the market cap of a lot of companies would be very different. The retail percentage of the market has had a major shift in recent years and sentiment counts a lot more now than it ever has.

The key underlying factor is supply and demand. What happens when every mining company is "fully priced"? They get sold off and sentiment moves to "the next" thing.

The idea that all of a sudden the demand for materials has changed is not correct. The demand has been there for a number of years now. The issue is really the ability to move the materials from one place to the next. That puts pressure on supply. The demand becomes stifled making it appear that demand has picked up. When supply lines normalize demand will likely decrease because it's easier to get in a faster timeframe. When this happens commodity prices drop. What we're seeing now is temporary. This is the same as what happened with BNPL. Demand picked up during a time when cash flow for the average person was constrained.

This will shift again and again as it always has over time. The key is finding good businesses in any sector that operates above it's peers. The metrics of course will be different in each industry, e.g. low cost of extraction for minerals or low bad debts higher margins in Fintech, etc, etc.

The shift of sentiment from sector to sector is endless for whatever is happening in the world will shift supply and demand.

Just my opinion
