After Reuters reported yesterday that Datawatch has hired a financial adviser after drawing expressions of acquisition interest from potential suitors, Craig-Hallum analyst Chad Bennett guessed there are a range of potential suitors, but said he thinks a visualization vendor makes the most strategic sense. Given Datawatch is a technology leader in the "hot space" of data preparation, Bennett believes his $18 price target on the stock is "in play" but also sees the possibility that a bid could come in higher. He maintains a Buy rating on Datawatch shares, which are up about 15% to $10.55 in pre-market trading.
