^ 100% agree with what Greg said as usual. Sebtarta, If you understand the company and industry and know why you want to invest in that company then go for it! I just know nothing at any kind of medical companies, and in my reference I just remember hearing lines in movies about how this pharma company could be "the next big thing." Which who knows, it could be! I just stick with super basic names I understand and can keep up with by scanning through their stuff a few minutes each day.
I highly encourage reading through as much as you can of this thread, good real life stuff here, good luck
