I've read some books and other resources on value investing (like this question)and fundamental analysis, but now I want more information on a specific sector: biotech. Is there a better way to start learning about a specific sector besides just googling stuff? I looked in the section of an index fund (IBB) prospectus that has things to say about the "principal risks", but that's just a couple of paragraphs.
Do I really just need a degree in biology or are there ways that investors who know more (maybe like people here) start learning about a specific sector before investing? I don't want investing recommendations because Im just looking for sources of info. Can anyone point me in the right direction whether or not you actually invest in biotech? Does anyone here know about the biotech sector?
