What were the reasons for the great c rash of the Long-Term Capital Management (LTCM) of hedge funds in 19981? In short: predatory trading. But what is predatory in effect? How can predatory trading occur? What are the consequences of predatory trading? How can predatory trading be avoided? These questions will be answered in the following paper. The following description gives a first impression of predatory trading: “When you smell blood in the water, you become a shark. ... when you know that one of your number is in trouble ... you try to figure out what he owns and you start shorting those stocks ..."2The first part of this paper deals with the basics of the model of the predatory trading theory, the second part elaborates the advantages and disadvantages which are summed up in the last part.

Objectives and Core Themes
This paper examines the predatory trading theory developed by Brunnermeier and Pedersen, aiming to understand how financial distress can lead to systemic market instability. It investigates the mechanics of how traders exploit distressed positions, the resulting price dynamics, and potential safeguards to mitigate such risks.
- The mechanics of predatory trading and price overshooting.
- Systemic risk and contagion effects in financial markets.
- The role of risk management and stress testing in preventing crises.
- Comparative analysis of the predatory trading model versus episodic liquidity crisis models.
- Practical implications for institutional regulators and market design.
Excerpt from the Book
2.3 The Predatory Phase (t ∈ [t0,T])
The predatory phase is cut into two stages. Stage one (exogenous default) is the phase where certain traders are already in financial straits (cf. part 2.3.1) and the role of the financial sound traders will be studied. Whereas stage two (endogenous default) endogenises the agents´ distress and describes how predatory trading can lead to a broad-base financial crisis (cf. section 2.3.2).
2.3.1 Exogenous Distress
2.3.1.1 Single Predator (Ip = 1)
The simplest assumption is the case with only one predator. The liquidation strategy of the distressed trader is familiar with the single predator. Consequently, the holding of securities of the distressed trader, Xi, is declining to zero. This leads to the new equilibrium by using Lemma 1 (cf. the appendix). The main prediction of this equilibrium is that both, the distressed trader and the predator, can sell simultaneously at the same speed and in the end, the predator repurchases the shares. Because of the selling of the predator, price-overshooting arises. The reason for this appearance is quite simple: because of the liquidation of the two agents, distressed trader and predator, there is an oversupply of shares. Therefore the price falls and the opportunity is seized by the predator who waits as long as the distressed trader has finished selling. Then the predator acquires the assets very cheaply and this leads to an increase of the price again.
Summary of Chapters
1. Introduction: Provides an overview of the predatory trading phenomenon, contextualized by the 1998 LTCM crash, and outlines the paper's structure.
2. Model: Establishes the theoretical foundations of the predatory trading model, including agent roles, trading constraints, and equilibrium conditions.
3. Critical Discussion: Evaluates the model's strengths, such as its practical relevance to market crises, while critiquing its assumptions and lack of concrete regulatory guidance.
4. Conclusion: Synthesizes the main findings, noting that while the model effectively illustrates contagion risks, it relies on strict assumptions regarding illiquid markets.

Frequently Asked Questions
What is the primary focus of this seminar paper?
The paper provides a critical examination of the predatory trading theory formulated by Brunnermeier and Pedersen, specifically analyzing how it explains the mechanism behind large-scale financial collapses like that of LTCM.
What are the core thematic areas discussed?
The discussion centers on market dynamics, the behavior of predatory traders during liquidation phases, the manifestation of systemic risk, and the effectiveness of risk mitigation strategies.
What is the central research objective?
The main objective is to define the mechanics of predatory trading, verify the model against empirical evidence, and identify both the positive contributions and the logical limitations of the theoretical framework.
Which scientific methodology is employed?
The author uses a analytical review approach, dissecting the mathematical model of Brunnermeier and Pedersen and comparing its assumptions and outcomes with alternative frameworks, such as the episodic liquidity crisis model.
What topics are covered in the main section?
The main section covers the model's basics, the predatory phase with single and multiple predators, the endogenization of distress, systemic risk, and potential market interventions like batch auctions.
Which keywords best characterize this work?
Key terms include Predatory Trading, Systemic Risk, Price Overshooting, Contagion, Liquidity, and Risk Management.
How does the author explain the concept of price overshooting?
Price overshooting occurs when predators exploit a distressed trader's forced liquidation by selling simultaneously, causing a temporary, exaggerated decline in asset prices, followed by an increase when the predator repurchases the assets.
Why is the LTCM crash considered a central example in this paper?
The LTCM case serves as a real-world case study for the model, illustrating how a highly leveraged fund's distress can cause systemic contagion, requiring intervention by major financial institutions to avert a broader sector collapse.
What critique does the author provide regarding the model's assumptions?
The author argues that the model's reliance on the condition of an "illiquid market" is somewhat unrealistic, as empirical data shows periods of extreme illiquidity are relatively rare, potentially limiting the theory's day-to-day applicability.
