I'm speculating and using available facts. Can you find a bioluminescent toxicity tester in the Hach offering of products? Do I state I'm a qualified water monitoring professional?
It's hardly been a shareholder dream, one look at the chart will tell you that.
"Is this price drop a good entry point or an indicator that the sale is/has not gone as well as wished"
A few posts later, the individual is able to appraise my gap-analysis of bioluminescent toxicity test machines available in the water monitoring market. Joker.
Doing a quick gap-analysis it looks to me like HACH would benefit from MW's Microtox® LX toxicity test system and have a recent history of M&A. Could be the suitor.
