Start with primary sources
Begin with company filings, investor-relations materials, earnings calls and regulator databases. Use news and commentary to identify questions, then verify important claims at the source.
Build a source hierarchy
Not every source deserves the same confidence.
- Tier 1: audited filings and official data
- Tier 2: company releases and transcripts
- Tier 3: reputable reporting and industry research
- Tier 4: commentary, social media and unverified claims
Keep an evidence log
For every important figure, save the source, date, link and your interpretation. This makes updates faster and allows teammates or judges to reproduce the work.
Use AI with verification
AI can help summarize, organize and challenge assumptions, but it can invent facts or lose context. Never submit a number, quotation or source link that you have not opened and verified yourself.
