[citation][nom]azxcvbnm321[/nom]Most acquirers' see a drop in their stock price after an announcement. That's because the buyer usually has to pay a premium to take over a company, and usually this leads them to drastically overpay.[/citation]
I'm not sure where you get your information, but it typically is quite the opposite. When there is an announcement of a possible merger or one company buying another, those stocks go up because 1.) the company buying it wouldn't be buying it unless they perceived a profit, and 2.) the company selling it wouldn't sell it unless they perceived a profit.
When both of those companies expect great things from the deal, their stocks go up. I don't think too many companies out there intentionally look to buy depreciating assets, and even though it occasionally happens due to poor judgement, it is far from the norm.
