The beta report uses closing prices from 24 August 2021 to 19 October 2026. The net-cash reports use the October 16, 2026 snapshot and June financial statements, and cover 25 identified stocks; whole-IDX completeness is not certified. Prices are historical, with no live updates.
How we make these
Production market data
The same daily prices, filings and financial statements behind the terminal, frozen once per report so every chart can be rebuilt.
Every number is sourced
Each report ends with its method, data window and sources. When a result is fragile, the report says so on the page.
Research, not advice
Reports explain what happened and what to expect. They don't tell you what to buy, and past results don't promise future ones.
