Introduction to Spread Arbitrage
Spread arbitrage is a financial trading strategy that capitalizes on price discrepancies between different markets or exchanges. Here's how it works:
- Core Principle: The strategy involves simultaneously taking long and short positions in related contracts to profit from changes in their price differentials.
- Cross-Exchange Arbitrage: This common approach exploits price differences between exchanges. Traders sell assets on higher-priced platforms and buy equivalent amounts on lower-priced ones, netting the difference as profit.
- Futures-Spot Arbitrage: This strategy leverages price gaps between spot and futures markets. When futures prices exceed spot prices, traders buy spot assets while selling futures contracts.
- Calendar Spread Arbitrage: This method focuses on price differences between futures contracts with different delivery months, capitalizing on temporary deviations from typical price relationships.
Calendar Spread Arbitrage Explained
Calendar spread arbitrage profits from price gaps between contracts with different delivery months. Traders monitor these gaps for deviations from historical norms, then execute pairs of trades to exploit the discrepancy.
Types of Calendar Spreads:
- Bull Spreads: Used when traders anticipate wider price gaps between distant and near-month contracts.
- Bear Spreads: Employed when traders expect narrower price gaps between contract months.
Execution Methods:
- Buy the Spread: When expecting price gaps to widen.
- Sell the Spread: When anticipating price gaps to narrow.
Practical Arbitrage: A Case Study
In cryptocurrency markets, price differences often exist between contracts for the same asset with different delivery dates. These contracts move in tandem, making spread arbitrage feasible.
Research Methodology
- Data Collection: Gather minute-by-minute, hourly, and daily price data for futures contracts from exchanges like Binance.
- Data Processing: Clean and organize the data for analysis.
- Spread Calculation: Compute price differences between near-month and far-month contracts.
- Visualization: Plot spread trends to identify patterns.
Spread Characteristics Analysis
- Descriptive Statistics: Calculate mean, standard deviation, and range to understand spread behavior.
- Rolling Features: Compute 20-period moving averages, standard deviations, and extreme values to identify trends.
- Stationarity Testing: Use Augmented Dickey-Fuller (ADF) tests to determine if spreads exhibit stable patterns suitable for arbitrage.
Key Takeaways
- Spread arbitrage leverages predictable price relationships between related instruments.
- Successful arbitrage requires careful analysis of historical price patterns and market conditions.
- Cryptocurrency markets offer numerous arbitrage opportunities due to frequent price discrepancies.
- Statistical tests help verify whether observed spreads represent genuine arbitrage opportunities.
