Investment Portfolio Risk Analysis & Return Projections
Core Idea
A comprehensive risk-adjusted portfolio analysis covering 10 stocks across aerospace, technology, and defense sectors, with HK$1,000,000 starting investment. The portfolio balances growth potential (RKLB, ASTS, SMT) against stability (GOOGL, RTX, PH) with detailed scenario modeling from 1-10 year horizons.
Why It Matters
- Structured Risk Framework: Clear categorization from LOW to VERY HIGH risk with specific mitigation strategies
- Probability-Weighted Scenarios: 5% to 50% probability assignments across best-to-worst cases
- Timeline Flexibility: Sharpe ratio improves from 0.25 (1Y) to 0.65 (10Y), favoring long-term holding
- Space Sector Concentration: 30% exposure (RKLB, ASTS, SMT) creates correlated risk from SpaceX competition

- Execution Risk - ASTS technology unproven at scale, RKLB Neutron delays
Related Concepts
- Portfolio rebalancing triggers
- Correlation analysis for diversification
- Hedge positions (options, inverse ETFs)
- Dollar-cost averaging for high-volatility positions
Next Steps
- Set quarterly rebalancing review dates
