RE:Let's talk about what CXR managment should/could be doing.
Relax. Companies do not panic over the very 'short' term fluctuations of SP like investors/traders do. They have communicated merger updates and have expressed confidence in their forecasts. When something material happens, you will know it. In the meantime, they need to focus on building value and paying down debt. The rest is just noise in the long term. Having said that, I feel your pain.
