RE:This doesn’t make any senseIt isn't unusual at all. If the news is monstrous, and people in the company knew about it, or even the chance that other people may have had heard, a good company will always halt so that people with inside information cannot take advantage before all shareholders have access to the same news. If the news is game-changing, then it is absolutley correct to halt trading. Since it has been halted all day, I suspect it is very big news.
