Everyone talks about which stock. We measure when.
Equity research on about 6,000 NYSE and NASDAQ listings. For each stock we measure its own price cycle, test its seasonal windows and read the insider filings behind them. Every call is dated when it is made and scored once its window closes, and members read the record.
Research, not investment advice.

What we publish, and what we never will
89stocks is impersonal, general-circulation research. It describes where each stock stands; it does not tell anyone what to do with their money.
Published
- The measured cycle phase of each stock, with how confident the measurement is.
- Seasonal windows that pass every test, with the years behind them.
- Insider filings, shown beside the cycle and the window.
- A positioning bias, never an instruction: accumulate, hold, trim or avoid.
- The date of every call, and later its outcome, on the record members read.
Never published
- Buy or sell instructions.
- Price targets.
- Position sizes.
- Backtested returns presented as a record.
- Anything fitted to a reader's own holdings.
