This thesis examines optimized portfolios of three investor types during four different time intervals ranging from 1998 to 2013 to determine if the inclusion of Treasury Inflation-Protected Securities (TIPS) has benefits for institutional investors such as pension plans, university endowments, foundations and sovereign wealth funds. The three investor types used in this study differ in their risk tolerance, with the more risk-averse investor type choosing not to include certain asset classes in his investment portfolio. The efficient frontier algorithm, developed by Prof. Harry Markowitz, is used to determine whether the inclusion of TIPS improves the risk/return profile of the portfolio. Sharpe ratio, developed by Prof. William Sharpe, is used to measure a portfolio’s risk adjusted performance. The study found that the benefits of the inclusion of TIPS in a portfolio vary by time period and investor type. While all investors were able to improve their risk return profile, the more risk-averse investor type benefits to a larger degree from the inclusion of TIPS. Furthermore, a significant increase in the financial efficiency was only observed in the 1998 to 2002 period. Therefore, the researcher concludes that the TIPS market is quite dynamic and investors need to take into account forward-looking information to profit from the inclusion of TIPS in investment portfolios.

Excerpt from the Book
II. Features
Treasury Inflation-Protected Securities (TIPS) are U.S. Treasury-issued notes and bonds. Their principal value is adjusted monthly for changes in the level of inflation as measured by the non-seasonally adjusted Consumer Price Index for All Urban Consumers (CPI-U) on a 2-month lag. Inflation-indexed bonds were created to meet the needs of longer-term investors wanting to insulate their investment principal from erosion due to inflation. These bonds have been issued in the United Kingdom (1981), Australia (1985), Canada (1991), the United States (1997) and France (1998).
The basic structure is the same for all US TIPS. A fixed coupon interest rate is paid semi-annually on the inflation-adjusted principal. At maturity, the principal is redeemed at the inflation-adjusted principal amount (but not less than par value). In other words, unlike the Canadian counterparts, TIPS issued in the U.S. are protected against the risk of deflation. The Department of Treasury provides a guarantee (floor) at the par value in a deflationary environment. As a result of this “guaranteed principal floor”, TIPS incorporate a minimal hedge against sustained deflation.
In the event of an absolute decline in the price level; i.e., deflation, over the life of an inflation protected bond, the Treasury will repay the full face value at maturity, insuring a floor for investors. That is, the principal of TIPS is increased by the percentage increase in the CPI or decreased by the percentage decrease in the CPI unless such adjustment would reduce the principal below its initial value. This asymmetric price-level adjustment feature provides TIPS investors with some protection against deflation in addition to the complete inflation protection.
Summary of Chapters
I. Introduction: This chapter provides an overview of U.S. government debt, focusing on the evolution and purpose of Treasury Inflation-Protected Securities (TIPS) and the researcher’s interest in their role for institutional investors.
II. Features: This chapter explains the structural characteristics of TIPS, including their inflation-adjustment mechanism, principal protection against deflation, and tax treatment.
III. TIPS in an Asset Allocation Framework: This chapter explores the theoretical rationale for treating TIPS as a unique asset class and discusses how they interact with other assets to improve portfolio diversification.
IV. Literature Review: This chapter reviews previous scholarly research regarding the relationship between TIPS, nominal bonds, and other asset classes, highlighting gaps in existing knowledge that this study addresses.
V. Methodology: This chapter details the use of the Modern Portfolio Theory, the efficient frontier algorithm, and the Sharpe ratio to evaluate the risk/return impact of including TIPS in various investment portfolios.
VI. Conclusions: This chapter summarizes the empirical findings, noting that TIPS provide significant efficiency gains particularly in specific market conditions, and discusses the trade-offs between portfolio concentration and diversification.

Frequently Asked Questions
What is the core focus of this thesis?
The thesis examines the role and effectiveness of Treasury Inflation-Protected Securities (TIPS) when integrated into optimized investment portfolios for different types of institutional investors.
What are the primary thematic areas covered?
The study centers on asset allocation, the application of Modern Portfolio Theory (MPT), inflation hedging, and the comparative risk-return performance of portfolios with and without TIPS.
What is the primary research objective?
The goal is to determine if adding TIPS improves the risk-return profile of a portfolio and whether these securities warrant being treated as a distinct asset class.
Which scientific methods are employed?
The researcher utilizes efficient frontier analysis (based on Markowitz’s model) and the Sharpe ratio to measure risk-adjusted performance across different time periods and constraints.
What topics are discussed in the main body?
The main body covers the technical structure of TIPS, the logic of asset allocation, literature review of relevant studies, and a quantitative analysis of various portfolio scenarios from 1998 to 2013.
What are the characterizing keywords of this work?
Key terms include TIPS, Asset Allocation, Efficient Frontier, Sharpe Ratio, Portfolio Optimization, and Inflation Hedge.
How does the study define different investor types?
Investor types are categorized by risk tolerance and portfolio constraints: Investor A is "progressive" (fully diversified), Investor B is "diversified" (excludes hedge funds/commodities), and Investor C is "traditional" (highly constrained).
What conclusion is drawn regarding the TIPS market?
The research concludes that the TIPS market is dynamic and that investors must incorporate forward-looking information to effectively profit from their inclusion in a portfolio.
What is the significance of the "guaranteed principal floor"?
It provides an asymmetric protection for investors, ensuring that even in sustained deflationary environments, the principal repaid at maturity is not less than the initial par value.
