I saw (felt) this happen. Worked for Acxiom when they were to be bought by Silverlake. The stock shot up to near-sale-price levels, where I should have sold (but did not). The deal came unraveled, Acxiom stock dropped like a rock and the company had a reputation as 'damaged goods' for many years. Lesson: There is a small upside, but a massive downside that can materialize.
