Suspicious Discontinuities: Understanding & Navigating Market Anomalies (2020 Edition)
Delve into the world of 'Suspicious Discontinuities,' a finance book analyzing 2020's market volatility. Learn key concepts, practical applications, and how to prepare for future anomalies.
The year 2020 was…different. The COVID-19 pandemic triggered a cascade of economic and financial events unlike anything seen in decades. Markets plummeted, rebounded, and behaved in ways that defied conventional wisdom. Understanding why this happened, and how to prepare for future unpredictable events, is crucial for any serious investor or finance professional. This is where “Suspicious Discontinuities: The Hidden Patterns Behind Market Volatility” by Menachem Brenner and Yigal Levy comes in. Published in 2020, it offers a powerful framework for analyzing and potentially profiting from these “suspicious discontinuities” – those moments when markets abruptly break from established trends.
What are Suspicious Discontinuities?
At its core, the book argues that markets aren’t random walks, but rather operate within predictable (though often long) cycles driven by human psychology, investor sentiment, and underlying economic forces. However, these cycles aren’t smooth; they’re punctuated by periods of intense volatility – the “suspicious discontinuities” – where past patterns seem to vanish.
These discontinuities aren't simply random shocks. They're the result of the build-up and eventual release of systemic tensions within the market. The authors identify several key factors that contribute to these events:
- Endogenous Risk: Risk created within the system, often through complex financial instruments or excessive leverage.
- Exogenous Shocks: External events (like pandemics, geopolitical crises, or natural disasters) that act as catalysts.
- Herding Behavior: The tendency of investors to follow the crowd, amplifying market movements.
- Reflexivity: The idea that investor perceptions can actually influence the underlying reality of the market. (George Soros is a prominent proponent of this concept.)
Key Concepts from "Suspicious Discontinuities"
The book doesn’t just identify the problem; it provides a toolkit for understanding and potentially exploiting these market anomalies. Here are some key concepts:
- The 8.7-Year Cycle: Brenner and Levy posit a recurring cycle of roughly 8.7 years, representing a period of economic expansion followed by a correction. They base this on historical analysis of global market data. While not perfect, the authors argue it provides a useful baseline for identifying potential turning points.
- The Importance of Debt: The book emphasizes the role of debt in amplifying both the upside and downside of economic cycles. Excessive debt accumulation creates vulnerability to shocks and can exacerbate market declines.
- Identifying Leading Indicators: Recognizing signals that suggest a discontinuity is approaching is vital. The authors suggest monitoring indicators like credit spreads, interest rate differentials, and investor sentiment.
- The Phases of a Discontinuity: Understanding where you are within a discontinuity – initial shock, panic selling, stabilization, and recovery – allows for more informed investment decisions.
- Behavioral Finance: The book heavily incorporates principles of behavioral finance, recognizing that human emotions play a significant role in market behavior, particularly during periods of stress.
Applying the Concepts: 2020 as a Case Study
"Suspicious Discontinuities" was published during the initial stages of the 2020 market crash, making it a particularly relevant case study. The authors meticulously analyze the events of early 2020, demonstrating how the pre-existing conditions – high levels of debt, stretched valuations, and a complacent market environment – made the system vulnerable to the exogenous shock of the pandemic.
They correctly identified several warning signs leading up to the crash, including:
- Inverted Yield Curve: An inverted yield curve (where short-term interest rates are higher than long-term rates) is often seen as a predictor of recession. This was present in late 2019.
- Credit Spreads Widening: Increasing spreads between corporate bond yields and government bond yields indicated growing concern about corporate creditworthiness.
- Euphoric Market Sentiment: A period of prolonged market gains had led to excessive optimism and risk-taking.
The book shows how these factors combined to create a perfect storm, resulting in the rapid market decline in February and March 2020. However, it also points out how the unprecedented government intervention – massive fiscal stimulus and quantitative easing – played a crucial role in the subsequent rapid recovery. This highlights the difficulty in predicting the magnitude and duration of discontinuities, as policy responses can significantly alter the outcome.
Trading Strategies & Risk Management
The book isn't just theoretical; it offers practical guidance for investors. While it doesn't advocate for specific trading strategies, it emphasizes the importance of:
- Diversification: Spreading investments across different asset classes to reduce risk.
- Defensive Positioning: Increasing cash holdings and reducing exposure to risky assets when warning signs emerge.
- Volatility Management: Using options or other strategies to hedge against potential market declines.
- Contrarian Thinking: Going against the crowd when market sentiment is extreme.
- Understanding Your Risk Tolerance: Investing in a way that aligns with your personal comfort level and financial goals.
The authors also stress the need for a long-term perspective. They argue that discontinuities, while painful in the short term, can present opportunities for astute investors who are prepared to act rationally. Buying undervalued assets during periods of panic selling can potentially generate significant returns in the long run.

Critiques and Limitations
While "Suspicious Discontinuities" provides a valuable framework for understanding market volatility, it's not without its limitations.
- The 8.7-Year Cycle: The authors acknowledge that the 8.7-year cycle isn’t a perfect predictor. There’s inherent variability, and the timing of discontinuities can be unpredictable.
- Hindsight Bias: Analyzing past events is easier than predicting future ones. Some critics argue that the book’s analysis of 2020 benefited from the clarity of hindsight.
- Complexity: The concepts presented in the book can be complex and require a solid understanding of finance and economics.
- Overreliance on Historical Patterns: Market dynamics evolve. Relying solely on past cycles without considering new factors (like the increasing influence of algorithmic trading) could be misleading.
Is "Suspicious Discontinuities" Worth Reading?
Absolutely. Despite its limitations, "Suspicious Discontinuities" is a thought-provoking and insightful book that challenges conventional wisdom about market behavior. It’s particularly relevant in the current environment, where economic uncertainty and geopolitical risks are high.
This book is recommended for:
- Experienced Investors: Those looking to refine their risk management strategies and gain a deeper understanding of market dynamics.
- Finance Professionals: Portfolio managers, analysts, and traders who want to improve their ability to identify and navigate market anomalies.
- Anyone Interested in Behavioral Finance: Those fascinated by the psychological factors that drive market behavior.
