5. **Understand share structure**: Multi-class can limit shareholder rights.

6. **Review lock-up terms**: Post-IPO supply pressure.

- **IPO diligence**: Understand companies preparing to go public
- **Competitive intelligence**: Analyze emerging competitors
- **Industry research**: Track sector trends through filings
