Hedge Funds — Relative Value Hedge Funds (CAIA Level I)

Hedge Funds — Relative Value Hedge Funds (CAIA Level I)

What Is It?

1. What is this topic? Relative value hedge funds exploit pricing inefficiencies between related securities (e.g., bonds, equities, derivatives) to generate alpha with low market exposure.
2. How is it tested/applied? CAIA tests classification, strategy mechanics, risk factors, and performance attribution. In practice, used for arbitrage, yield enhancement, and portfolio diversification.

Why Does the Exam Ask This?

CAIA assesses whether candidates can: - Identify relative value strategies (e.g., fixed-income arb, convertible arb, volatility arb). - Understand risk factors (liquidity, credit, basis risk) and their impact on returns. - Evaluate performance in different market regimes (e.g., widening vs. tightening spreads). - Apply due diligence to strategy selection and manager evaluation.

What Do I Need to Know First?

1. Arbitrage principles (law of one price, no-arbitrage conditions).
2. Fixed-income basics (yield curves, duration, credit spreads).
3. Derivatives (futures, options, swaps).
4. Market microstructure (liquidity, bid-ask spreads).
5. Hedge fund risk metrics (Sharpe ratio, drawdowns, leverage).

Topic Snapshot

Relative value is a core CAIA Level I topic under "Hedge Fund Strategies." It bridges arbitrage theory with real-world implementation, emphasizing risk management and strategy differentiation. Mastery is critical for due diligence and portfolio construction.

Must-Know Rules, Formulas, Standards, or Principles

1. No-Arbitrage Principle: If two securities have identical cash flows, their prices must converge.
2. Formula: Price_A = Price_B (adjusted for financing costs).
3. Basis Risk: The risk that the spread between two related securities fails to converge.
4. Key Idea: Basis = Spot Price - Futures Price (for futures arb).
5. Leverage Effect: Relative value strategies often use leverage to amplify small mispricings.
6. Rule: Leverage increases both returns and tail risk (e.g., LTCM collapse).

Misconceptions

1. "Relative value is risk-free." → Mispricing convergence is not guaranteed (e.g., liquidity crises).
2. "All relative value strategies are market-neutral." → Some have directional exposure (e.g., convertible arb).
3. "Higher leverage always means higher returns." → Leverage magnifies losses in stress events.
4. "Volatility arb is just about options pricing." → It also involves dynamic hedging and skew trading.
5. "Fixed-income arb is only about yield curves." → Credit risk and liquidity are equally critical.

Common Mistakes

1. Ignoring tail risk (e.g., assuming spreads will always tighten).
2. Overlooking funding costs in arbitrage trades (e.g., repo rates, margin requirements).
3. Misclassifying strategies (e.g., confusing statistical arb with fixed-income arb).
4. Underestimating liquidity risk (e.g., assuming bonds are as liquid as equities).
5. Failing to adjust for basis risk in futures vs. cash trades.

The Common Trap

Assuming "market-neutral" means "risk-free." - Why it’s tempting: Relative value strategies often hedge market exposure, masking underlying risks (e.g., credit, liquidity). - Real-world impact: Funds like LTCM collapsed despite being "market-neutral" due to ignored tail risks.

Terms to Remember

1. Basis Risk – Divergence between hedged positions (e.g., futures vs. cash).
2. Convertible Arbitrage – Long convertible bonds + short underlying stock to exploit mispricing.
3. Volatility Arbitrage – Trading implied vs. realized volatility (e.g., delta-hedged options).
4. Liquidity Risk – Inability to exit positions without price impact.
5. Leverage Effect – Borrowed capital amplifying returns (and losses).

Step-by-Step Process

1. Strategy Identification

• Classify the relative value strategy:
• Fixed-Income Arb (yield curve, credit spreads).
• Convertible Arb (bond vs. stock mispricing).
• Volatility Arb (implied vs. realized vol).
• Statistical Arb (mean-reversion in pairs).

2. Trade Construction

• Long/short setup: Buy undervalued, sell overvalued (e.g., long corporate bonds, short Treasuries).
• Hedging: Neutralize market exposure (e.g., delta-hedging in convertible arb).
• Leverage: Apply borrowed capital to enhance returns (but monitor risk limits).

3. Risk Management

• Monitor basis risk (e.g., futures roll costs).
• Stress-test liquidity (e.g., can you exit positions in a crisis?).
• Set stop-losses for drawdowns (e.g., 10% max loss per trade).

4. Performance Attribution

• Alpha sources: Spread convergence, volatility capture, carry.
• Risk factors: Credit, liquidity, funding costs.

Exam Answer Builder

1-Mark Question (MCQ)

What it tests: Strategy classification. Example: Which relative value strategy involves trading implied vs. realized volatility? A) Fixed-income arbitrage B) Convertible arbitrage C) Volatility arbitrage D) Merger arbitrage Correct Answer: C Key Tip: Memorize the core mechanic of each strategy.

2-Mark Question (Short Answer)

What it tests: Risk identification. Example: A relative value fund is long corporate bonds and short Treasuries. Name two risks it faces. Model Answer: 1. Credit risk (corporate bond default). 2. Liquidity risk (widening bid-ask spreads in a crisis). Key Tip: Link risks to the specific trade (e.g., "short Treasuries" → funding risk).

3-Mark Question (Calculation)

What it tests: Arbitrage pricing. Example: A 5-year corporate bond yields 6%, while a 5-year Treasury yields 3%. The credit spread is 3%. If the spread widens to 4%, what is the P&L impact on a $10M long corporate/short Treasury position? Model Answer: - Initial spread: 3% → 6% - 3% = 3%. - New spread: 4% → 7% - 3% = 4%. - Spread change: +1% (100 bps). - P&L: -$10M × 1% = -$100,000. Key Tip: Always calculate spread changes in basis points (bps).

5-Mark Question (Case Study)

What it tests: Strategy evaluation. Example: A hedge fund runs a fixed-income arb strategy: long BBB corporates, short Treasuries. During a recession, credit spreads widen, and liquidity dries up. Explain the impact on the fund’s P&L and two risk management actions the manager should take. Model Answer: 1. P&L Impact: Losses from widening spreads (long corporates fall more than Treasuries). 2. Risk Actions:
- Reduce leverage to limit margin calls.
- Hedge tail risk with credit default swaps (CDS). Key Tip: Address both P&L and risk mitigation.

This vs That: Relative Value vs. Directional Hedge Funds

Time-Saver Hack

Eliminate wrong answers in MCQs: - If a question asks about volatility trading, eliminate options mentioning credit spreads or mergers. - If a question asks about liquidity risk, eliminate options about interest rate risk (unless it’s a fixed-income arb question).

Mini Scenarios

1. Basic Scenario

A fund is long a 5-year corporate bond and short a 5-year Treasury. What is the primary risk? What to notice: Credit risk (corporate bond default) and basis risk (spreads may not converge).

2. Applied Scenario

A convertible arb fund is long a convertible bond and short the underlying stock. The stock price drops 20%. What happens to the fund’s P&L? What to notice: Delta-hedging may offset some losses, but gamma risk (non-linear moves) can cause slippage.

3. Tricky Scenario

A volatility arb fund sells straddles (short puts + calls) on a stock. The stock gaps down 30% overnight. What is the fund’s exposure? What to notice: Vega risk (volatility spike) and gap risk (unhedged tail moves). The fund loses money on both legs.

Diagnostic MCQ Bank

Easy

Question: Which strategy profits from mispricing between a bond and its embedded option? A) Fixed-income arbitrage B) Convertible arbitrage C) Merger arbitrage D) Volatility arbitrage Correct Answer: B Explanation: Convertible arb exploits mispricing between a convertible bond and its underlying stock. Trap Option: A (fixed-income arb focuses on yield curves, not embedded options).

Medium

Question: A relative value fund is long $10M of 10-year corporates (yield 5%) and short $10M of 10-year Treasuries (yield 2%). If the credit spread widens by 50 bps, what is the P&L? A) -$50,000 B) -$500,000 C) +$50,000 D) +$500,000 Correct Answer: B Explanation: P&L = -$10M × 0.5% = -$50,000 (but duration matters; assume 10-year duration → -$500,000). Trap Option: A (ignores duration impact).

Hard

Question: During a liquidity crisis, a fixed-income arb fund’s corporate bond positions drop 15%, while Treasuries drop 5%. The fund is 3x levered. What is the approximate equity drawdown? A) 15% B) 30% C) 45% D) 60% Correct Answer: C Explanation: - Net loss = (15% - 5%) = 10% on $10M = $1M. - Leverage = 3x → $3M equity loss on $10M capital → 30% drawdown (but bond prices are more volatile → 45%). Trap Option: B (underestimates leverage effect).

Real-World Patterns

1. Liquidity Crunches: Relative value funds often blow up when spreads widen (e.g., 2008, 2020).
2. Regulatory Scrutiny: Leverage limits (e.g., SEC rules) force funds to adjust positions.
3. Performance Chasing: Investors pile into relative value after spreads tighten (e.g., 2021), only to face drawdowns when spreads widen.

30-Second Cheat Sheet

1. Core Idea: Exploit mispricings between related securities.
