Overview of Arbitrage Trading
Arbitrage trading has become a primary strategy in global financial markets due to its stable returns and relatively low risk. Institutional investors, including large funds, often engage in futures or options markets using arbitrage or partial arbitrage strategies. With the diversification of listed commodities in regulated markets like China’s futures exchanges, numerous arbitrage opportunities arise, making it an effective tool for major market participants.
Arbitrage trading, also known as interest arbitrage or carry trade, involves exploiting short-term interest rate differentials between countries or regions. Funds are transferred from low-interest-rate areas to higher-yielding ones to capture interest differentials. In futures markets, arbitrage entails simultaneously buying and selling different types of contracts.
Key Characteristics:
- Focus on Price Relationships: Traders analyze the relative price between contracts rather than absolute price levels.
- Risk Management: Positions are hedged by buying undervalued and selling overvalued contracts. Profits arise if the price discrepancy corrects as anticipated.
- Prerequisites: Arbitrage is viable only if the cost of arbitrage (or the forward discount on high-interest currencies) is lower than the interest rate differential between the two currencies.
Role of Arbitrage in Futures Markets
Arbitrage serves two critical functions:
- Hedging Mechanism: Provides investors with opportunities to mitigate risk.
- Price Correction: Helps realign distorted market prices to equilibrium levels.
Classification of Arbitrage Strategies
1. Intertemporal Arbitrage (Calendar Spread)
- Exploits price differences between contract months for the same commodity.
2. Intermarket Arbitrage
- Capitalizes on price disparities of the same commodity across different exchanges.
3. Intercommodity Arbitrage
- Trades correlated commodities with the same expiration month (e.g., gold vs. silver).
4. Covered vs. Uncovered Arbitrage
- Uncovered Arbitrage: No hedge against currency risk; relies solely on interest rate differentials.
- Covered Arbitrage: Combines arbitrage with forward contracts to eliminate exchange rate risk.
Advantages and Limitations of Arbitrage
Advantages
- Lower Volatility: Price spreads fluctuate less than individual contract prices.
- Limited Risk: Hedged positions reduce exposure to market swings.
- Crash Protection: Resilient during extreme price movements (e.g., trading halts).
- Attractive Risk/Reward Ratio: Higher success probability compared to directional trades.
Limitations
- Capped Profits: Potential gains are constrained by the nature of spread trades.
- Infrequent Opportunities: Efficient markets offer fewer arbitrage openings.
- Execution Risks: Price divergences may persist longer than anticipated, leading to temporary losses.
Risk Assessment in Arbitrage
Key Risks:
- Adverse Spread Movement (80% weight): Primary concern; requires strict stop-loss measures.
- Delivery Risks (10% weight): Issues with contract settlements or warehouse receipts.
- Extreme Market Events (10% weight): Rare but impactful (e.g., forced liquidations).
Why Choose Arbitrage Trading?
Hedging Market Uncertainties
- Reduces volatility by offsetting price risks in correlated assets.
- Examples: Cash-and-carry arbitrage ensures limited risk by locking in physical delivery spreads.
Independent Trading Strategy
- Appeals to conservative investors and large funds seeking steady returns.
- Ideal for capital preservation without speculative exposure.
