CVS goes down every single day because CVS has nothing to look forward to except losses.
WAG goes up every day because WAG has only gains to look forward to.
Here's what they're saying about CVS:
"CVS took a huge bet on Aetna with low masrgins and "backed into" both the FED and calPERS due to MHS "fouls." ESRX has remedied and will take these contracts away in '13. Aetna is a loser. Blues defected a few months ago. The WAG/ESRX reunion was the final straw. RUN...do not walk."
