Filings and financial statements.
Company filings come from OpenDART (Korea), SEC EDGAR (US) and MOPS (Taiwan), as filed, with a link to the original. Financial statements come from DART for Korean companies and Twelve Data elsewhere. Earnings dates come from the same filing systems and, for Japan, the exchange's 45-day disclosure rule.
Analyst estimates.
Targets and ratings for US and Taiwanese companies are Twelve Data's consensus. For Korean companies they are averaged from Korean broker reports: each broker's latest report in the last three months.
How the AI reports are written.
Angle reports, sector reports and the morning brief are written by AI models from the data above, with web search for current headlines. Each report shows the figures it used and names its sources. A run that doesn't reach a conclusion is marked as such and kept out of search. Nothing on AlphaLenz is investment advice.
Four languages.
Reports are written in Korean and translated into English, Japanese and Chinese by AI with a finance glossary. A report not yet translated is shown in Korean with a note, and that language's page is kept out of search until it is. Every page has a link to report a translation problem.
