This study uses OLS regressions to analyze the impact of institutional ownership (IO) investment horizons on stock price synchronicity and crash risk for a sample of U.S. companies. Two main hypotheses are tested:
(1) long-term (short-term) IO (LTIO) (STIO) are negatively (positively) related to stock price synchronicity, and
(2) long-term (short-term) IO are negatively (positively) related stock price crash risk.
Stock price synchronicity (SYNCH) measures how much firm-specific returns align with overall market returns, while crash risk (NCSKEW, DUVOL, COUNT) indicates the likelihood of a sudden, significant price drop. The theory posits that short-term investors, more prone to sell shares, provide weaker oversight, giving managers more freedom to influence cash flows and increasing synchronicity. In contrast, long-term investors establish stronger management relationships, reducing synchronicity through enhanced oversight.
The findings reveal that both long-term and short-term IO positively impact synchronicity, contradicting the hypothesis for long-term IO. This aligns with literature suggesting institutional investors use superior information mainly for trading rather than management engagement.
For crash risk, results support the agency theory: long-term IO is associated with reduced crash risk due to better monitoring, while short-term IO correlates with higher crash risk due to frequent trading and weaker oversight. These findings align with prior research, indicating that bad news is disclosed under long-term monitoring, causing abrupt price drops.
During the 2008 financial crisis, average crash risk was significantly higher, especially for financial firms. The interaction between IO horizons and the crisis suggests complex dynamics needing further study, particularly the negative interaction of long-term and aggregated IO during recessions.
Robustness checks, including firm fixed-effects regressions and variable changes, confirm primary findings but suggest cautious interpretation for long-term IO results. Limitations include a relatively short observation period (2000-2017), potential measurement biases in tax avoidance proxies (long-run cash effective tax rate (LRETR)), and unaddressed endogeneity concerns.
Future research should explore evolving ownership structures, corporate social responsibility, and impacts of recent disruptions like the COVID-19 pandemic on crash risk.

Research Objectives and Themes
The primary objective of this thesis is to empirically investigate how different investment horizons of institutional investors influence both stock price synchronicity and stock price crash risk within U.S. companies. The research aims to clarify whether long-term institutional investors act as effective monitors who mitigate agency problems, or if their behavior differs significantly from that of short-term, transient institutional investors.

- Impact of institutional investor heterogeneity (long-term vs. short-term) on crash risk

Excerpt from the Book
1 Introduction
Over the past two decades, there were repeated corporate scandals, such as the accounting fraud at WorldCom, the bad news hoarding behavior at Enron and many others from Xerox to Wirecard. In the wake of stock price crashes, the number of empirical studies on crash risk has increased rapidly, focusing mainly on the United States (U.S.) and China (Ali et al., 2022). A crash as described occurs when the manager withholds bad news from the investors, leading to an accumulation of firm-specific bad information, which eventually crosses a tipping point where all the bad news is released at once (Hutton et al., 2009; Jin and Myers, 2006). In particular, the global financial crisis showed that this does not necessarily remain an isolated case.
An important factor on the management side is the degree of informational freedom that a company can be managed with. This level of freedom is determined by legal regulations and supervisory authorities as well as the behavior of investors and shareholders. A distinction between control and ownership assumes that firm owners benefit from the actions of the manger, but also bear the risks. To ensure that the manager makes decisions in the interest of the owners, a variety of actions can be taken that influence the decisions. Jensen and Meckling (1976) describe the resulting principal-agent framework as the relationship between managers (agents) and investors (principals), in which several principals hire an agent to perform services on their behalf. The agency problems arising from this relationship and how to mitigate these issues have become an important part of the academic literature.

Frequently Asked Questions
What is the core focus of this research?
The work focuses on analyzing the impact of institutional investors' investment horizons on stock price synchronicity and stock price crash risk within the U.S. market.
Which theoretical concept serves as the foundation?
The research is primarily grounded in the principal-agent theory, exploring how institutional monitoring mitigates agency problems.
What is the primary research question?
The thesis investigates whether different types of institutional investors (long-term vs. short-term) influence firm-specific market outcomes like crash risk and synchronicity differently.
Which scientific methodology is applied?
The author uses empirical ordinary least squares (OLS) regressions, utilizing firm-level data and fixed-effects models, to test the formulated hypotheses.
What are the main thematic areas covered?
The work covers agency theory, the classification of institutional investors, variables such as stock price synchronicity and volatility, and specific impacts during the financial crisis.
How is the research structured?
It is divided into five main chapters: introduction, literature review, data and methodology, regression results, and the concluding summary.
What distinguishes long-term from short-term institutional investors in this study?
Long-term investors are categorized as dedicated or passive monitors with larger stakes, while short-term investors are described as transient and prone to selling shares quickly when firm performance is poor.
Why is the financial crisis considered a special case in the study?
The financial crisis acts as a natural experiment to observe if institutional monitoring effectiveness changes under conditions of heightened market risk and recession.
