Wow, you cover so many bio stocks, Dew & I thank you for keeping us informed!
I only allow myself a maximum of 8-10 stocks in my portfolio, but most include major companies with proven earnings results and trustworthy management ...they make mistakes but are honest.
I have an interest in biotech companies because I believe they offer an opportunity for lasting cures for many dreaded illnesses...really think gene therapy and gene editing will provide the answers at some point, probably after 5 years or so. I've tried to invest in a few for my grandchildren.
