What You Can Do

You can construct investment theses for long/short portfolios by identifying catalysts, pairing longs with hedges to isolate alpha, quantifying conviction probabilistically, and stress-testing outcomes across market dislocations. The framework produces reproducible, risk-committee-ready documentation that replaces ad-hoc position thinking with disciplined position mechanics and hedge optimization.

Features

Thesis Articulation

Identify specific catalysts, timeframes, and financial inflection points that drive your investment case with testable milestones

Multi-Leg Structuring

Pair long positions with appropriate shorts to reduce systematic risk, isolate alpha, and optimize portfolio construction

Conviction Quantification

Express confidence probabilistically with edge decay assumptions and confidence intervals tied to conviction levels

Hedge Ratio Optimization

Calculate beta-neutral, market-neutral, or directional hedge ratios based on correlation, volatility, and portfolio constraints

Scenario Stress Testing

Model outcomes across market dislocations, regulatory shifts, sector rotations, and idiosyncratic shocks pre-entry

Risk Committee Documentation

Generate systematic position documentation that survives LP scrutiny and internal risk review

Rebalancing Framework

Update conviction, correlations, and hedge ratios when market conditions or thesis developments change

Example Output

Example 1: Long Tech / Short Semiconductor Thesis

Catalyst: AI capex normalization reducing fab utilization below 75% in H2 Long: Nvidia (conviction 7/10, $120 upside) Short: TSMC (conviction 6/10, $85 downside) Hedge Ratio: 1.3x TSMC to beta-neutral portfolio (correlation 0.72, NVDA beta 1.8) Stress Test: If AI spending delays 6 months, position loses $2.1M; if energy costs spike 30%, TSMC shorts gain $1.2M

Example 2: Long Specialty Retail / Short Fast Fashion

Thesis: Inventory normalization drives margin expansion; fast fashion margin compression from excess supply Long: Lululemon (conviction 8/10, margin expansion catalyst Q2) Short: H&M (conviction 7/10, working capital strain) Hedge Ratio: 0.9x for directional beta exposure (isolated apparel retail idiosyncratic risk) Scenario: Recession scenario (-15% consumer spend) results in $800K loss; strong consumer scenario (+10%) yields $2.8M gain
