There is nothing in your links to cause this... The company has an amazing Board, impressive management team, very very very strong insider buying, a product now approved in the EU, and lastly is worth at least three times the current share price.
The company already has interest in the product, is attending in a week the premier conference for their specialty, and yesterday's move in share price is in no way reflective of the true value.
A large investor (for a nano-cap like this large is a few hundred thousand shares) sold. Why? Not sure. However, he/she did. This caused a massive sell off.
This will be up 20% by the end of the week.
