If it is free, there is little market data, and it can only be collected through different channels to form its own database.
Later, I mainly used the following channels to take pharmaceutical stocks as an example for reference.
A special website of pharmaceutical industry, such as Bio-Valley, contains a lot of fragmentary information, which needs to be actively sorted out;
China Tiandi Medicinal Materials Network, learn about the price of the original medicinal materials and other related information.
SFDA is the authoritative website of the US Food and Drug Administration, the approval and distribution of drugs.
China Food Approval and Certification Bureau website, understand the certification of vaccines, blood products and other biological products, other, I won't go into details.
Second, go to the websites of listed companies, where there are detailed introductions of the company's main products, and some have different market shares.
The data of F 10 three quotation softwares are mainly analyzed, some of them are still useful, and there are company comments.
Four financial websites, sporadic introduction and market share of some products.
Securities newspapers often exist, as long as you pay attention,
The website of the exchange contains detailed financial report, annual report (such as product share) and prospectus, which is the most detailed. I suggest you read it carefully. I believe it is very useful to you.
7. About the research report of securities firms, personal experience is optional. At present, there are not many quality reports, most of which are grandstanding, or the goods are not the right version, making wedding clothes for others.
Eight, it is necessary to suggest a personal data analysis library, which may take time and patience to accumulate and take a long time to benefit.
I wish you a fortune!
