Why are so few rare earths companies profitable? What are some quality ones to invest in?

After the Trump admin's announcement that they are building a $12bn rare earths stockpile, many rare earths stocks have been rising since yesterday, with some soaring to 15%+ today. I've been doing some research on the 5 biggest winners of today, and none of them are profitable. **$NB - NioCorp** 0% profit margin; -76% return on equity **$TMC - The Metals Company** 0% profit margin; -59% return on equity **$IE - Ivanhoe Electric** 0% profit margin; -24% return on equity **$UAMY - United States Antimony Corporation** \-15.5% profit margin; -10.2% return on equity **$CRML - Critical Metals Corp** 0% profit margin; -128.3% return on equity Are investors just chasing hype or is there a actual strategy for this money piling in? Are these companies expected to become profitable from this deal? What are some quality companies that will benefit from the rare earths stockpile that are healthy/profitable companies?
