Personal Stock Picking Framework
A semi-focused, deep-research approach to equity investing combining fundamental analysis, catalyst identification, and valuation discipline.
Framework Philosophy
Approach: Semi-focused with concentrated positions in deeply researched ideas Thesis Horizon: Medium to long-term with catalyst-driven entry/exit Validation: Combination of DCF analysis, trading multiples, and structural situational advantages
The Three-Part Process
1. Opportunity Identification
Screening Criteria:
- Sector focus: Semiconductors, technology hardware, infrastructure, and geopolitical themes
- Market inefficiency: Overlooked small/mid-cap names, activist situations, or misunderstood catalysts
- Structural advantages: Durable competitive moats, network effects, or structural cost advantages
- Management quality: Proven capital allocation, shareholder alignment, skin-in-the-game
Sources:
- Equity research reports from specialized firms
- Industry transcripts and management commentary
- Technical deep dives and fundamental analyses
- Activist/private equity intelligence
- Geopolitical policy analysis impacting sector dynamics
2. Deep Fundamental Research
Core Due Diligence:
Market Opportunity
- TAM (Total Addressable Market) and serviceable market size
- Growth catalysts and demand tailwinds
- Competitive positioning and market share trends
- Pricing power and margin expansion potential
Financial Model
- Revenue drivers and realistic growth assumptions
- Operating margin profile and scalability
- Cash generation and capital intensity
- Balance sheet strength and financial flexibility
Competitive Dynamics
- Relative technology position vs. competitors
- Customer concentration and switching costs
- Supply chain dependencies and supplier power
- Patent moats and R&D effectiveness
Management & Capital Allocation
- Track record of disciplined capital deployment
- Acquisition track record (bolt-on vs. transformational)
- Shareholder return mechanisms (buybacks, dividends, debt reduction)
- Governance structure and alignment signals
3. Valuation & Entry
Valuation Methods:
Discounted Cash Flow (DCF)
- Build bottoms-up model with explicit growth assumptions
- Use WACC calibrated to sector and company risk profile
- Sensitivity analysis on key drivers (revenue growth, margins, terminal growth)
- Assess intrinsic value vs. market price for margin of safety
Trading Multiples
- EV/Sales, P/E, EV/EBITDA relative to peers and history
- Identify when valuations compress (value trap detection)
- Use multiples to validate DCF conclusions
- Understand what market is implying about growth/margins
Sum-of-the-Parts (SOTP)
- For diversified or platform companies with multiple segments
- Value each segment separately using appropriate multiples
- Identify hidden value or optionality not reflected in aggregate valuation
Catalyst-Driven Catalysts:
- Product launches or roadmap inflection points
- Market share gains from competitive displacement
- Margin expansion from mix shift or cost reduction
- Strategic events (M&A, partnerships, capital structure changes)
- Geopolitical policy changes affecting supply/demand
Position Sizing & Risk Management
Position Construction:
- Core positions (5-8) in deeply researched, high-conviction ideas
- Size positions by conviction and valuation margin of safety
- Avoid over-concentration; typical position: 3-8% of portfolio
- Reserve dry powder for incremental buying on weakness
Risk Controls:
- Define downside case and maximum acceptable loss
- Monitor quarterly results against model assumptions
- Reassess thesis quarterly; act quickly on falsification
- Use stop-losses to prevent catastrophic position decay
Exit Signals:
- Target valuation achieved; redeploy to higher conviction idea
- Catalyst materializes but stock doesn't respond; reassess thesis
- Fundamental assumption breaks; model refinement or exit
- Better risk/reward elsewhere; opportunity cost discipline
Information Hierarchy
Highest Weight:
- Primary research (management calls, industry experts, trade shows)
- Company fundamentals (financial statements, product roadmaps, customer wins)
- Specialized equity research from domain experts
- Structural/geopolitical analysis on sector tailwinds
Medium Weight: 5. Consensus analyst estimates and target prices 6. Trading technicals and sentiment indicators 7. Comparable company benchmarking
Lower Weight: 8. General market commentary and macro narrative 9. Social media and retail consensus
Key Disciplines
Do:
- Maintain detailed investment theses with explicit assumptions
- Update models quarterly with actual results
- Track your batting average and learn from misses
- Invest time in understanding the business operationally, not just financially
- Challenge your own biases and seek contrary evidence
Don't:
- Invest in ideas you can't explain simply and completely
- Hold positions beyond their fundamental rationale
- Average down without reassessing the core thesis
- Let sunk costs or ego prevent thesis abandonment
- Confuse high-conviction with high-certainty
Sector Focus Areas
Based on KB content depth:
- Semiconductors: Foundries, equipment, materials, packaging, design
- Data center infrastructure: Power delivery, cooling, networking, structures
- AI/Compute: GPU/accelerator companies, foundational models, inference infrastructure
- Geopolitical: Export controls, China strategy, CHIPS Act implementation, supply chain reshoring
- Automotive & EV: Power electronics, ADAS/autonomous, battery materials
