Nope, I'm not wondering. Btw it was more like 40% drop in Dy usage and it was the move to AC motors that caused it. HRE is still used in rotors of AC motors and even Tesla is now reverting back to RE permanent magnets. FYI Dy is also increasingly used in lighting and lasers.
Now that GM has gone back to manufacturing EVs what's the betting they going to need more Dy then they did for the past several years ?

Anyway, I'm not interested in debating every detail behind the use of the mineral dug up and processed by NTU anymore then being interested in debating and researching hearing devices and how to perform implants just because I happen to own COH. The same goes for all my other stocks as I 'd rather spend time sailing or enjoying my time then being stuck in front of a screen researching or ramping my stock and downramping the competition. Besides, most normal people I know buy stock based on a company's and management performance and let them get on with managing it, that's what management is supposed to get paid for.
Even if I had no family, no friends, no hobbies, no job, nobody to talk to at home, etc. there would not be enough hours in a day to research and post on more then a couple of stocks at best let alone 20+ stocks.

Haven't quite figured out if you post on NTU because you are insecure about your own investment, have an obsession with REs, if you are just trolling here, trying to prove something to NTU holders or maybe something else. I'm giving up trying but whatever it is I'm sure you will eventually figure it out. Suggest you also read

Good luck with your investment and hope it goes back to $27 soon. In hindsight I should have listened to the LT NTU holders when when I first posted here and put you on Ignore.
Oh well, better late then never.
