Shareholder nuisance lawsuits can happen basically any time the stock goes down... or doesn't go up enough, and often companies will settle instead of the expensive fighting...
Something bad happens, stock goes down, angry shareholders sue because they should have been told the bad thing would happen and the stock would go down.
