For ~38 days, a cronjob generated daily forecasts:
• 30 stocks across different sectors
• 10-day horizons
• ~30 predictions/day (different stocks across multiple sectors)
• Fixed prompt and parameters
Each run logs:
• Predicted price
• Natural-language rationale
• Sentiment
• Self-reported confidence
Because the runs were captured live, this dataset is time-locked and can’t be recreated retroactively.
### Platform
I built a simple MVP to explore the data interactively:

You can browse and crawl all recorded runs here

.
### Goal
This is not a trading system or financial advice.
The goal is to study how LLMs behave over time under uncertainty:
forecast stability, narrative drift, confidence calibration, and prompt-conditioned bias.
### Dataset
After ~1.5 months, I’m publishing the full dataset on Hugging Face.
It includes forecasts, rationales, sentiment, and confidence.
(Actual prices are rehydratable due to licensing.)
