CNTF - b/c investors don't look at cash. One knock on the company is that they are very conservative with their cash. They don't seem to want to do anything with it, like buy back shares.
I think you can trust that they are legit b/c (1) they have not done secondary offerings (as so many other cash rich companies, i.e., CELM, CCME, CBEH, ZSTN, etc. have done) and (2) they reported heavy losses in the past that occurred for well-defined fundamental reasons. So they tell the truth.
When in their histories have CELM, CCME, CBEH, or ZSTN ever reported losses?
