Here is who knows about PMCB. Shareholders, Large pharma who have signed NDA's and Doctors in the Pancreatic Cancer and Diabetes world. None of the Doctors or Large Pharma can pass this company onto buyers or traders as it would be viewed as Insider Trading. That leaves the 1900 current shareholders. They already own their shares. Some own as many they are comfortable with and are not adding. Until the PR's hit those real traders and buyers who normally never even look at OTC stocks, it will sit at these levels. That's how it works. That's why I only own shares in one OTC.
Here are examples from social media that should help understand how few people are aware of PMCB. Below are the number of Likes on each Pharma's Facebook page.
Johnson & Johnson - 692,000 Pfizer - 167,000 Novartis - 177,000
PMCB has exactly 434 Likes on their page. May seem like a silly example but I think it shows exactly how few people know about this company.
