MSOFT Stock Trading Halted on News...

The news that Microsoft may have dodged a bullet caused their stock to rise over 3 points this morning before “trading was halted”. Why would it be halted? What’s so bad about a single stock going up too fast?

Trading of a specific stock is generally halted when big news about the company comes out.

“good” or “bad” isn’t the issue with a market halt. Order imbalance is - in either direction (too many buyers OR too many sellers). They halted to allow the news to get digested in hopes that an orderly market can be maintained when they open it up again.
