The Complete Arbitrage Deskbook

By Stephane Reverre

Quick Summary

A comprehensive professional reference on arbitrage strategies across equities, fixed income, and derivatives, covering the theoretical foundations, practical mechanics, and risk management of index arbitrage, pairs trading, risk arbitrage, convertible arbitrage, fixed income arbitrage, and cross-asset strategies. Reverre writes from the perspective of a practicing arbitrageur, emphasizing the operational details and real-world complications that textbooks typically ignore.

Executive Summary

Stephane Reverre's "The Complete Arbitrage Deskbook" provides an integrated, practitioner-oriented view of arbitrage across all major financial markets. The book is organized in three parts: theory and tools (defining arbitrage, covering financial instruments, and explaining valuation and risk analysis), practical application (examining specific arbitrage strategies in detail), and integrated examples (bringing all concepts together through real-world case studies). Reverre's key contribution is his insistence on covering the "zillions of small details" that determine whether an arbitrage is truly riskless or merely appears so: stock borrowing costs, dividend timing, margin requirements, settlement risk, fiscal treatment, corporate action exposure, and execution timing. The book covers index arbitrage (exploiting discrepancies between index futures and their underlying baskets), pairs trading and statistical arbitrage, risk arbitrage (merger/acquisition situations), convertible arbitrage, and fixed income arbitrage (yield curve, basis, and swap spread trades).

Core Thesis

True arbitrage is the simultaneous purchase and sale of essentially similar securities for advantageously different prices. In practice, most "arbitrage" strategies carry some residual risk, and the arbitrageur's edge comes not from the theoretical concept but from mastering the operational details -- financing costs, margin requirements, execution risk, corporate actions, and tax implications -- that determine actual profitability.

Key Concepts and Frameworks

1. Index Arbitrage -- Exploiting the basis between an index future and its underlying cash basket. When the future trades at a premium above fair value (accounting for financing costs and dividends), the arbitrageur sells the future and buys the basket; when it trades at a discount, the reverse. Transaction costs and execution risk define the "no-arbitrage band."
2. Pairs Trading and Statistical Arbitrage -- Trading the spread between correlated securities that have temporarily diverged from their historical relationship. The strategy is market-neutral but carries the risk that the historical relationship breaks down permanently.
3. Risk Arbitrage -- Taking positions in announced merger/acquisition situations, typically buying the target and shorting the acquirer. The spread compensates for deal risk (regulatory, financing, or shareholder approval failure).
4. Convertible Arbitrage -- Buying convertible bonds and shorting the underlying stock to isolate the bond's embedded optionality and credit spread. Requires dynamic hedging of the delta and monitoring of credit risk.
5. Fixed Income Arbitrage -- Yield curve trades, basis trades (cash versus futures), swap spread trades, and relative value trades across the fixed income universe. These strategies are typically highly leveraged and carry significant liquidity risk.
6. Fiscal Arbitrage -- Exploiting differences in tax treatment of securities across jurisdictions. Stock lending and borrowing, which appears simple, involves complex fiscal considerations that create genuine arbitrage opportunities.

Practical Applications for Traders

1. Always calculate the full cost of an arbitrage position including financing, borrowing, dividends, and execution costs before assuming profitability.
2. Understand that the "no-arbitrage band" in index arbitrage is wider than theoretical models suggest due to real-world frictions.
3. In risk arbitrage, size positions according to deal certainty and time to completion -- never treat announced deals as certain.
4. Monitor corporate actions carefully; dividends, stock splits, and rights issues can destroy the economics of an otherwise sound arbitrage.
5. Recognize that leverage amplifies both returns and risks in fixed income arbitrage -- LTCM's failure is the cautionary tale.

Critical Assessment

Strengths

• Exceptionally detailed treatment of operational and practical considerations that other texts ignore
• Written from genuine practitioner experience, not academic theory
• Covers all major asset classes and arbitrage strategies in a single volume
• The emphasis on fiscal and financing details reflects the reality of professional arbitrage

Limitations

• Highly technical; requires substantial background in finance and derivatives
• Some sections on specific instruments (particularly pre-euro European markets) are dated
• Limited coverage of statistical/quantitative approaches to arbitrage
• The mathematical notation and presentation can be dense

Historical Significance

Published in 2001, this book filled a significant gap between academic texts on arbitrage theory and the practical reality of running an arbitrage desk. It remains one of the few books that treats arbitrage as an integrated, cross-asset discipline rather than isolating individual strategies.

Conclusion

"The Complete Arbitrage Deskbook" is an essential reference for anyone involved in professional arbitrage trading. Reverre's insistence on covering the operational details -- the stock lending mechanics, dividend timing, margin calculations, and settlement risk that actually determine profitability -- distinguishes this book from the many texts that present arbitrage as a purely theoretical exercise. While the technical demands are high, any trader or risk manager who works with arbitrage strategies will find this book indispensable for understanding the practical complexities that separate theoretical opportunity from actual profit.
