# AShareIntel > A factual research database for China A-share companies, reported top shareholders, and changes between public reporting periods. AShareIntel covers companies listed on the Shanghai and Shenzhen stock exchanges. The site is published for research and informational use only. It does not provide investment advice, stock recommendations, asset management, or personalized financial guidance. The current comparison uses the 2026 first-quarter report and the 2026 interim report. Only companies with ten named shareholders and positive share quantities in both periods are included in period-over-period comparisons. Terms such as “new appearance” and “no longer appears” describe changes in a company's disclosed top-ten shareholder list. They do not establish that an institution bought, sold, entered, or exited the stock. ## Core pages - [Company directory](https://ashareintel.com/companies): Browse and search China A-share companies. - [Institution directory](https://ashareintel.com/institutions): Browse tracked international financial institutions and reported holdings changes. - [XML sitemap](https://ashareintel.com/sitemap.xml): Index of public company and institution pages. - [Full AI guide](https://ashareintel.com/llms-full.txt): Detailed scope, methodology, terminology, and URL patterns. ## Contact - Email: hello@ashareintel.com
