Here, the investor made a belief that an acquisition takes place only when both the acquirer and acquire benefit from the deal. The acquirer agrees to make a deal if it sees potential in it and the targeted company accepts the deal if the purchased price offered is greater than its current market price.

Impact On the Stock price of the acquiring company

In an acquisition, the market tends to choose favorites. In other words, investors tend to look for winners and losers in the proposed deal. Since the acquiring company is making the purchase, unless the profitability of the deal is not evident to the investors, the stock price of the acquiring company tends to get affected negatively.
