Institutional investors face serious challenges due to the current low interest rate environment and their payment obligations. Life insurance companies in Germany have invested the majority of their assets in fixed-income securities. Thus, asset managers struggle to earn adequate returns as a consequence of low yields of high-grade sovereign bonds. As a consequence, institutional investors are forced to rethink their asset allocation, which is vital for the investment success.
This thesis aims to evaluate asset allocation strategies in the light of the low interest rate environment that enable investors to generate adequate risk-adjusted returns. A sample portfolio is developed that is broadly diversified, has exposure to alternative investments and applies the Risk Parity ap-proach. The performance is evaluated over different evaluation periods on a risk-adjusted basis and in comparison to other asset allocation strategies. As a result, the sample portfolio outper-forms the current asset allocation of German life insurers and naïve diversification. However, portfolios with significant exposure to private equity or stocks outperform the sample portfolio in terms of Sharpe ratio but require a higher risk tolerance. Nevertheless, the sample portfolio achieves a satisfactory risk and return profile and is well balanced in terms of risk contribution.

Research Objectives and Key Themes
This thesis examines the asset allocation challenges faced by institutional investors, specifically German life insurance companies, within a prolonged low-interest-rate environment. The primary research question is whether a broadly diversified portfolio—utilizing a risk-based investment approach like Risk Parity and incorporating alternative assets—can provide better risk-adjusted returns and improved portfolio stability compared to traditional, bond-heavy strategies.
- Impact of the low-interest-rate environment on institutional asset management.
- Evaluation of Modern Portfolio Theory (MPT) and its practical limitations.
- Analysis of institutional investment models, including the Yale Endowment Model.
- Implementation of a sample portfolio using a Risk Parity strategy and passive ETF-based investment.
- Comparative performance evaluation against traditional and index-based benchmarks.
Excerpt from the Book
The Mean-Variance Portfolio as an Optimum?
As mentioned previously, Markowitz’s mean-variance approach does not provide the investor with one optimum portfolio, but portfolio selection depends on the investor and his or her individual return and risk preference. With regard to the difficulties in estimation of input parameters as well as the definition of the investor’s preference function, the question arises whether the mean-variance analysis as part of the Markowitz model is best for an investor or if there are more suitable alternatives.
According to Frahm and Wiechers, the benefits of quantitative asset allocation strategies in general are questionable and part of continued discussions in literature. Considering the parameter estimation complexity, applying quantitative methods in estimating the input parameters suffers from estimation errors as a main problem. Additionally, the mean-variance analysis is highly sensitive to input parameters. Hence, there is a strong momentum away from mean-variance optimization and towards more robust alternatives such as the minimum-variance or heuristic approaches, in particular risk budgeting strategies. The minimum-variance strategy for example targets on minimizing the overall portfolio return variance and similarly to a risk budgeting portfolio does not depend (explicitly) on estimations of the expected asset returns. Contrary to the Markowitz model, only the risk dimension is considered and the expected returns are assumed to be identical for all assets since the performance dimension is usually too complicated to forecast.

Frequently Asked Questions
What is the core focus of this Master's thesis?
This thesis focuses on how institutional investors, particularly German life insurance companies, can rethink their asset allocation strategies to generate sufficient returns in a persistently low-interest-rate environment.
What are the primary investment strategies discussed?
The work centers on broad diversification, the use of alternative investments, passive investing via ETFs, and the implementation of a Risk Parity approach.
What is the primary objective of the research?
The goal is to determine if a portfolio incorporating alternative assets and a risk-based strategy can outperform traditional, fixed-income-heavy portfolios while providing superior risk-adjusted returns.
What methodology is used to test these strategies?
The author developed a €10 billion sample portfolio using ETF instruments and conducted both a five-month performance monitoring period and a three-year backtesting analysis against various market benchmarks.
What does the main body of the work cover?
It covers the theoretical foundations of Modern Portfolio Theory, the specific challenges of current capital markets, an analysis of status quo institutional management, and a detailed practical case study of portfolio construction and management.
Which key metrics characterize the study?
Key metrics include the Sharpe ratio for risk-adjusted return comparison, Tracking Error, Value at Risk (VaR), and Treynor Ratio, among others.
Why does the author prioritize ETFs for the sample portfolio?
ETFs are used because they offer low management fees, high transparency, and liquidity, aligning with the thesis's support for passive investment strategies in efficient or semi-efficient markets.
How do the Yale Endowment and German Life Insurer models compare in this thesis?
The thesis contrasts the highly diversified, alternative-asset-heavy strategy of the Yale Endowment with the conservative, bond-heavy strategy typical of German life insurers, highlighting the performance gaps between them.
