This morning Johnson Matthey (JMAT) issued just the sort of news that investors will not have wanted to see, announcing its intent to exit the battery materials sector and as a result its share price has plummeted.

Atalaya Mining (ATYM) has been a favourite of mine for a few years now, but seems to be one of those shares which you rarely see mentioned on social media and the bulletin boards. It was formerly EMED. Ring a bell?
