AI-Powered Stock Analysis & Forecasting
Explore model-generated stock forecasts, understand their limitations, and review how performance is measured.
Forecasts are model estimates, not guarantees. Market conditions change, losses are possible, and past or backtested results do not guarantee future returns. Nothing here is investment advice.

Performance summary
The system is under evaluation
We do not publish a headline accuracy claim. The most complete, unselected evaluation we have is a retrospective walk-forward backtest. It was not recorded before the outcomes were known.

How it works
Three steps
1. Market data
Adjusted daily prices are downloaded from a public market-data source and checked for gaps before use.
2. Model evaluation
Each model is tested walk-forward on dates it was not trained on and compared with a simple baseline.
3. Forecast generation
The latest model produces a next-session direction forecast, which is saved with a timestamp and scored once the outcome is known.
