Halted based on what though?

You can only halt if there's material news.

If there were talks but not formal offers there's nothing to halt.
If there were settlement discussions that were "very positive" but no agreement signed there's nothing to halt.

You can have all sorts of leaks with no real way to halt the stock - because nothing is signed or agreed on yet.
