Earnings calls, Fed press conferences, and investor days contain some of the most valuable unstructured information in markets.
Most investors either skip them or listen in real time — both are inefficient. OpenClaw automates the entire pipeline: transcript monitoring, audio transcription, tone analysis, and language change detection. This series builds five production pipelines covering every major source of spoken and transcribed financial content.
What this series covers
| Part | Source | Cost | Cadence |
|---|---|---|---|
| Earnings Call Transcripts | Motley Fool / Seeking Alpha RSS | Free | Quarterly per company |
| Fed & FOMC | federalreserve.gov | Free | 8 meetings/year + speeches |
| Audio Transcription | OpenAI Whisper API | ~$0.006/min | On-demand |
| NLP & Tone Analysis | LLM via OpenClaw | LLM API cost only | On each transcript |
| Investor Days & Conferences | SEC 8-K + IR page scraping | Free | Event-driven |
Two modes
Mode 1 — Text monitoring
When transcripts are already published as text (earnings calls, Fed minutes), OpenClaw monitors for new publications and processes them automatically.
Mode 2 — Audio transcription
When content is published as audio/video only (investor days, roadshows, some Fed events), OpenClaw downloads the file and runs Whisper to produce a searchable transcript before analysis.
Who this is for
- Long-term investors who want to track management language over multiple quarters
- Analysts who need to process high volumes of transcripts quickly
- Macro traders tracking Fed communication shifts
- Journalists monitoring corporate and regulatory language changes
