Options as a Strategic Investment by Lawrence McMillan

The Definitive Options Reference

If there is one book that belongs on every options trader's shelf, it is Options as a Strategic Investment by Lawrence G. McMillan. First published in 1980 and now in its fifth edition, this book has earned its reputation as the most comprehensive options reference ever written. At over 1,000 pages, it covers virtually every options strategy in existence, from the most basic covered calls to advanced volatility plays.

What the Book Covers

McMillan organizes the material in a logical progression that takes readers from foundational concepts to sophisticated strategies:

• Options Fundamentals -- the mechanics of calls and puts, how options are priced, and the role of intrinsic and extrinsic value. McMillan explains these concepts with exceptional clarity, making them accessible even to readers with no prior options experience.
• Basic Strategies -- covered calls, protective puts, bull and bear spreads. Each strategy is presented with detailed profit and loss diagrams, breakeven calculations, and practical examples showing when and why you would use it.
• Advanced Strategies -- straddles, strangles, ratio spreads, backspreads, butterflies, condors, and calendar spreads. McMillan goes deep into the mechanics of each, explaining how Greeks interact and how to manage positions as market conditions change.
• Volatility Trading -- an entire section dedicated to understanding and trading volatility. McMillan explains implied versus historical volatility, volatility skew, and how to build positions that profit from volatility expansion or contraction.
• Index Options and Futures -- strategies specific to index products, which is directly relevant to 0DTE traders who focus on SPY and QQQ.

Why It Matters for 0DTE Traders

You might wonder why a 1,000-page reference book matters when you are trading options that expire in hours, not months. The answer is that understanding the full landscape of options behavior makes you a better short-term trader. Here is why:

Understanding Gamma and Theta at Expiration. McMillan provides one of the clearest explanations of how options behave as expiration approaches. Gamma accelerates dramatically in the final hours, meaning small price moves in the underlying create large swings in option value. Theta decay, meanwhile, is at its most aggressive. 0DTE traders live in this environment every day, and McMillan's framework helps you understand exactly why your positions move the way they do.

Spread Construction. Many 0DTE traders use vertical spreads to define risk. McMillan's detailed treatment of bull call spreads, bear put spreads, and credit spreads gives you a deep understanding of how strike selection, width, and premium affect your risk-reward profile. This knowledge translates directly to building better 0DTE spreads.

Volatility Awareness. McMillan dedicates hundreds of pages to volatility concepts. For 0DTE traders, understanding how implied volatility affects premium pricing is essential. On high-IV days, premiums are inflated and selling strategies can be more attractive. On low-IV days, buying strategies may offer better value. McMillan gives you the conceptual tools to make these assessments quickly.

How to Read It

This is not a book you read cover to cover in a weekend. Treat it as a reference that you return to as your trading evolves. Start with the fundamentals chapters to build a solid foundation. Then study the chapters on spreads and volatility trading, which are most relevant to 0DTE work. Keep it nearby and revisit sections as you encounter new situations in your trading.

Our Take

Options as a Strategic Investment is the book that separates casual options participants from serious traders. The depth of coverage is unmatched, and McMillan's explanations are precise without being overly academic. If you are committed to trading 0DTE options with a real edge, the knowledge in this book will pay for itself many times over.
