Information Sources
Finding reliable information is the foundation of good research. Knowing where to look and what to trust separates good analysts from poor ones.
The best investors develop systematic research processes. They know exactly where to find each piece of information they need.
Primary Sources
Direct from the company – most reliable:
Annual Report
The gold standard for company information:
| Section | What You'll Find |
|---|---|
| Auditor's Report | External verification |
| Management Discussion | Business analysis |
Read annual reports of competitors too. They often reveal more about industry dynamics than the target company's report.
Quarterly Results
Timely updates:
- Revenue and profit for the quarter
- Management commentary
- Segment-wise performance
- Order book updates
Investor Presentations
Company's view for investors:
- Strategy overview
- Key highlights
- Industry context
- Often more visual than annual reports
Conference Calls
Direct access to management:
- Quarterly earnings calls
- Analyst day presentations
- Questions from analysts
- Management tone and confidence
Transcripts available on company websites or research platforms.
Regulatory Filings
Stock Exchange Filings
| Type | Information |
|---|---|
| Material events | Important announcements |
SEBI/RoC Filings
- Prospectuses (RHP, DRHP)

Regulatory filings are legal documents. Companies are liable for their accuracy. They're more reliable than press reports.
