Long and short investment thesis development

Build investment theses for long and short positions with synthesized research across SEC filings, competitive dynamics, and macro context. Generate a first-draft investment memo in minutes rather than days.

Build a short thesis on US commercial office REITs. I want vacancy rates by major market, refinancing risk on 2025–2026 debt maturities, names with highest leverage, and any recent dividend cuts as distress signals.

Compiled 6-section memo. Vacancy: San Francisco 36%, Chicago 26%, Manhattan 22% (all 20-year highs). Debt maturities: $54B in office REIT debt due 2025–2026 at rates originally set at 3–4%, now refinancing at 7–8%. Most stressed: SL Green (LTV 48%, debt/EBITDA 9.2x), Vornado (cut dividend 29% in 2023), Columbia Property Trust (taken private after distress). Highest-conviction short: SL Green and Vornado. Risk: NYC office recovery in financial district.

Daily portfolio and risk monitoring

Run the morning portfolio risk check — pull overnight price moves for all positions, flag anything that moved more than 4%, check macro conditions, and confirm gross and net exposure are within limits.

Morning risk check: pull prices for our top 10 longs and 5 shorts. Flag any that moved more than 5% from yesterday. Show me the current VIX and 10-year Treasury yield.

Flagged 2 moves: NVDA +6.2% (earnings beat overnight — positive for our long, consider partial trim). SLG -4.8% (NYC office data worse than expected — short thesis continuing to work). Other 13 positions within normal range. VIX: 18.4 (calm). 10Y Treasury: 4.41% (up 4bp). No stop-loss triggers hit. Net exposure: 42% long (within 30–60% target range).

Pre-investment regulatory screening

Before adding a new position, screen the company and its management for SEC enforcement history, shareholder class actions, and FINRA violations. Catch regulatory landmines before they surface in the stock.

Before we size up our long in Evolent Health (EVH), screen the company and CEO for any SEC, DOJ, or state insurance regulatory actions. Also check for shareholder class action lawsuits.

Evolent Health: 1 SEC comment letter (2022, routine accounting inquiry — closed with no action). No enforcement actions against CEO or management. Shareholder class action: filed 2023 related to forward guidance — settled for $7.5M in Feb 2024 (immaterial). No regulatory disqualification concerns. Company holds state insurance licenses in 32 states — check DOI licenses separately for disciplinary history.

Macro theme and credit cycle research

Research macroeconomic themes that drive top-down sector tilts and geographic allocation. Get synthesized, cited analysis on Fed policy, credit cycle dynamics, and whether to run more or less net long exposure.

Build a macro brief on the credit cycle heading into 2026. I want: leveraged loan default rates, high yield spread trends, Fed lending standards survey, and whether we should reduce our cyclical long exposure.

Credit brief compiled from BofA, Goldman, and Fed SLOOS data. Leveraged loan default rate: 3.2% LTM (up from 1.4% in 2022, well below 2009 peak of 10.8%). HY spread: OAS 320bp (historically tight, below 10-year average of 450bp). Fed SLOOS: 40% of banks tightening lending standards (leading indicator of corporate stress, 6-12 month lag). Conclusion: credit tightening but not in crisis. Reduce cyclical longs 10–15%, particularly consumer discretionary and commercial real estate.

Quarterly investor letter drafting

Draft the quarterly investor letter: build the performance attribution charts, calculate net returns and fees, and get a first draft of the macro and thesis narrative sections.

Draft the opening section of our Q1 investor letter: fund returned +8.4% net, HFRI Equity Hedge benchmark +5.2%. Top contributor: NVDA long (+3.1% contribution). Largest detractor: consumer discretionary short (-0.8%). Macro context: S&P 500 +10.6% but concentrated in 7 stocks.

Draft Q1 letter opening: "The XYZ Fund returned +8.4% net of fees in Q1 2026, outperforming the HFRI Equity Hedge benchmark by 320 basis points. Equity markets advanced sharply with the S&P 500 gaining 10.6%, though performance remained highly concentrated — the seven largest technology companies accounted for 74% of the index return. Our outperformance reflected selective exposure to AI infrastructure beneficiaries, particularly our long in Nvidia (NVDA), which contributed +3.1% to fund returns following its February earnings beat. Our consumer discretionary short was the primary detractor at -0.8% as the sector proved more resilient than our thesis anticipated..." [full 4-paragraph section generated].

Frequently Asked Questions

How do I structure a short thesis to present to my team?

A strong short memo has six sections: (1) one-line thesis statement, (2) why the market is wrong — the specific consensus view you are fading, (3) fundamental analysis from SEC filings showing the disconnect from current valuation, (4) catalysts — specific events that will drive the stock lower and on what timeline, (5) risks and stop-loss level, and (6) position sizing rationale. The catalyst section is most critical — a correct short thesis without a near-term catalyst is an expensive experience.

What SEC disclosure requirements apply to hedge funds?

Key filings: Form ADV (investment adviser registration, updated annually). Form 13F (quarterly disclosure of US long equity positions above $100M AUM threshold, filed within 45 days of quarter end). Form 13G/13D (when you cross 5% ownership in a public company). Form PF (for private fund advisers with >$150M AUM — quarterly or annual depending on size). The Regulatory Actions tool can help check for any SEC comment letters or deficiency notices related to these filings.

How do I calculate gross and net exposure?

Gross exposure = sum of all long positions (% of NAV) + sum of all short positions (% of NAV, absolute value). Net exposure = sum of longs minus sum of shorts. Example: $100M long, $40M short, $200M NAV = 50% gross long + 20% gross short = 70% total gross, 30% net long. Most long-short equity funds run 70–120% gross and 30–60% net long.

What is a high water mark and how does it affect performance fees?

The high water mark is the highest NAV per unit the fund has ever achieved. Performance fees are only charged on returns above the high water mark — preventing double-charging on recovered losses. Example: fund at $100 earns 20% to $120. Performance fee charged on $20. Fund falls to $110, recovers to $125. Performance fee only applies to the $5 gain above the prior $120 high water mark.

How do I set position size limits for a long-short book?

Common limits: maximum single long position 8–10% of NAV (5% for shorts since losses are theoretically unlimited). Maximum sector concentration 25–30% gross. Risk-based sizing: size each position so a 20% adverse move costs no more than 1% of NAV — this caps each position at approximately 5% net for a 20% stop. Shorts should be sized smaller than equivalent longs given the asymmetric loss profile.
