## Resource

Sebastian Krog shares his transition from a pure stock picker to a disciplined portfolio manager. He explores how managing 'thesis drift' and prioritizing industry dynamics over management narratives are critical for microcap success.

## Highlights
- Main idea: Successful microcap investing requires tracking the evolution of your thesis rather than just the initial entry price
- Practical takeaway: Prioritize industry-wide dynamics and structural shifts, as these often outweigh individual management performance
- Failure mode: Avoid 'thesis drift' by resisting the urge to hold speculative turnarounds that fail to meet operational milestones
- Practical takeaway: Use management calls as a way to build 'reps' and improve your ability to judge leadership through volume and experience
- Investment strategy: Focus on position management by letting your best performers drive the portfolio's overall returns
