Kurzbeschreibung des Verlags

A practical guide to designing, pricing, and managing butterfly option trades as focused volatility relative-value positions. This book explains how strike selection, wing width, expiration, skew, term structure, and local volatility interact, giving readers a structured framework for evaluating trades beyond a simple view on whether markets will rise or fall.From the basic call, put, and symmetric butterfly to complex portfolios spread across strikes and maturities, the material connects theory with implementation. Clear payoff analysis is paired with volatility-surface interpretation, model comparison, execution planning, dynamic hedging, and post-trade review.What the book covers- Core structures: construct butterflies, identify breakevens, assess maximum profit and loss, and compare narrow and wide wing profiles.- Risk and Greeks: analyze delta, gamma, vega, theta, rho, vanna, volga, charm, and color at both leg and portfolio level.- Surface relative value: read implied volatility by strike and expiration, work in moneyness or delta space, interpolate sparse quotes, and assess richness or cheapness without relying on a directional forecast.- Skew and curvature: use risk reversals, strangles, and butterflies to isolate smile geometry, express or neutralize skew, and manage delta drift as market conditions change.- Term structure: evaluate calendarized butterflies, separate strike effects from maturity effects, and measure carry, roll, and time decay across expirations.- Local volatility and models: understand the Dupire framework, surface derivatives, numerical instability, calibration, and the differences between Black-Scholes, local-volatility, stochastic-volatility, and hybrid approaches.- Trade implementation: choose strikes and order types, estimate bid-ask costs and slippage, control legging risk, and calculate realistic net entry value.- Ongoing management: establish delta-hedging rules, examine gamma scalping, hedge vega and volga across maturities, and respond to spot moves, volatility shifts, and decay.- Portfolio and research discipline: manage concentration, liquidity, margin, scenario risk, data quality, backtesting bias, trade records, and performance attribution.Designed for practical applicationEach chapter concludes with a worked example, including index butterfly construction, volatility-surface ranking, model-price comparison, execution-cost estimation, daily position management, portfolio stress testing, and complete entry-to-exit review. These examples show how a trade thesis becomes a measurable position with defined exposures, costs, controls, and attribution.Suitable for derivatives traders, volatility researchers, quantitative analysts, portfolio managers, and advanced students, this resource offers a disciplined way to judge whether a butterfly is genuinely mispriced, understand the risks behind its apparent payoff, and manage the position throughout its life.
