Introduction to Asset Allocation
Summary
Trang 2Elements of Effective Investment Governance and Investment
Governance Considerations in Asset Allocation
Governance and management are separate but related functions
▪ Governance: clarify the mission, create a plan, and review progress
▪ Management effort is focused on outcomes: execution of the plan to achieve agreed-on goals
A common governance structure in an institutional investor context will have three levels
1) governing investment committee 2) investment staff and 3) third-party resources
Effective governance models perform the following tasks:
1 Articulate the long-term and short-term objectives of the investment program
2 Allocate decision rights and responsibilities among the functional units in the governance hierarchy effectively, taking account of their knowledge, capacity, time, and position in the governance hierarchy
3 Specify processes for developing and approving the investment policy statement that will govern the day-to-day operations of the investment program
4 Specify processes for developing and approving the program’s strategic asset allocation
5 Establish a reporting framework to monitor the program’s progress toward the agreed-on goals and objectives
6 Periodically undertake a governance audit
Trang 3The Economic Balance Sheet and Implication for Asset Allocation
• An economic balance sheet includes:
▪ Conventional (financial) assets and liabilities
▪ Extended portfolio assets and liabilities
• For individual investors, extended portfolio assets/liabilities include:
▪ Assets: human capital, PV of pension income, PV of expected inheritances
▪ Liabilities: PV of future consumption
• For institutional investors, examples of extended portfolio assets/liabilities include:
▪ Assets: underground mineral resources, PV of future intellectual property royalties
▪ Liabilities: PV of prospective payouts for foundations
• Extended portfolio assets and liabilities should be considered in making asset
allocation decisions
Trang 4Investment Objectives of Asset-Only, Liability-Relative
and Goals-Based Asset Allocation Approaches
Asset Allocation
Approach
Relation to Economic Balance Sheet Typical Objective Typical Uses and Asset Owner Types Asset only Does not explicitly model
liabilities or goals
Maximize Sharpe ratio for acceptable level of volatility
Liabilities or goals not defined and/or simplicity is important
• Some foundations, endowments
• Sovereign wealth funds
• Individual investors
Liability relative Models legal and
quasi-liabilities
Fund liabilities and invest excess assets for growth
Penalty for not meeting liabilities high
• Banks
• Defined benefit pensions
• Insurers
Goals based Models goals Achieve goals with specified
required probabilities of success
Individual investors

Asset Allocation
Approach
Relation to Economic Balance Sheet Relevant Risk Concepts Asset only Does not explicitly
model liabilities or goals
Primary risk measure is volatility of portfolio returns which depend
on asset class volatilities and correlation Risk relative to benchmark (tracking error) Downside risk
Monte Carlo simulations
Liability relative Models legal and
quasi-liabilities
Shortfall risk: risk of having insufficient assets to pay obligations when due
Goals based Models goals Risk of failing to achieve goals
Risk limits: maximum acceptable probability of not achieving goals Overall portfolio risk is the weighted sum of the risks associated with each goal
Trang 6Use of Asset Classes to Represent Exposure to Systematic Risk and Criteria for Asset Class Specification
Asset class: “a set of assets that bear some fundamental economic similarities to each other, and that have characteristics that make them distinct from other assets that are not part of that class.”
Criteria for Asset Class Specification
1 Assets within an asset class should be relatively homogeneous
2 Asset classes should be mutually exclusive
3 Asset classes should be diversifying
4 The asset classes as a group should make up a preponderance of world investable wealth
5 Asset classes selected for investment should have the capacity to absorb a meaningful proportion of an
investor’s portfolio
Sources of risk for broadly defined asset classes (equity versus debt) are better distinguished than sources
of risk for narrowly defined subgroups (large cap versus small cap equity)
Even broadly defined asset classes (US equity and US Corporate Bonds) have some common risk factor
exposures non-zero correlation between asset classes
Risk factors are associated with non-diversifiable (systematic) expected return premium
Trang 7Use of Risk Factors in Asset Allocation and their Relation to
Traditional Asset Class-Based Approaches
At times an investor’s goals and objectives cannot be met through traditional asset classes
Risk factor approaches to asset allocation focus on assigning investments to the investor’s desired exposures to specified risk factors
Examples of how risk factor exposures can be achieved:
• Inflation Going long nominal Treasuries and short inflation-linked bonds isolates the inflation component
• Real interest rates Inflation-linked bonds provide a proxy for real interest rates
Bonds

Asset only Liabilities or goals not defined and/or simplicity is important
Suitable for: some foundations, endowments, sovereign wealth funds, individual investors
Liability relative Penalty for not meeting liabilities high
Suitable for: banks, defined benefit pensions, insurers
Goals based Suitable for some individual investors
Trang 9Use of Global Market Portfolio as Baseline Portfolio in Asset
Allocation
Global market-value weighted portfolio should be the baseline asset allocation
• Represents all investable assets minimizes non-diversifiable risk
• Investing in the global market portfolio helps mitigate investment biases such as home country bias
Investing in the global market portfolio is done in two phases:
• Allocate assets in proportion to the global portfolio of stocks, bonds, and real assets
• Disaggregate each broad asset class into regional, country, and security weights using capitalization weights
Implementation hurdles:
• Size of each asset class on a global basis can’t be precisely determined
• Not practical to invest proportionately in residential real estate
• Private commercial real estate and global private equity assets are not easily carved into pieces of a size that is accessible to most investors
Proxies for the global market portfolio are often based only on traded assets, such as portfolios of exchange-traded
Trang 10Strategic Implementation Choices in Asset Allocation
• Passive/active management of asset class weights
▪ Passive strategy: stick to strategic asset allocation (SAA)
▪ Active strategy: allow deviation from SAA
➢Called tactical asset allocation (TAA)
• Passive/active management of allocations to asset classes
▪ Passive strategy: each asset class based on relevant benchmark
▪ Active strategy: deviate from asset class benchmark
• Risk budgeting: which risks to take and to what extent
▪ Can be stated in absolute or relative terms
▪ Active risk budgeting: how much benchmark-relative risk an investor is willing to
take in seeking to outperform a benchmark; two levels of active risk budgeting
➢ Overall asset allocation level
➢ Individual asset class level
Factors impacting active vs passive investment decision:
• Available investments
• Scalability of active strategies being considered
• Feasibility of investing passively given constraints
• Beliefs concerning market informational efficiency
• Cost-benefit trade-off
• Tax status
Trang 11Strategic Considerations in Rebalancing Asset Allocations
Rebalancing: discipline of adjusting portfolio weights to more closely align with the strategic asset allocation Without rebalancing the overall portfolio risk rises
IPS should specify rebalancing policy and who is responsible for rebalancing
Calendar rebalancing versus percent-range rebalancing
▪ How frequently is the portfolio valued?
▪ What size deviation triggers rebalancing?
▪ Is the deviation from the target allocation fully or partially corrected?
• Higher transaction costs for an asset class imply wider rebalancing ranges
• More risk-averse investors will have tighter rebalancing ranges
• Less correlated assets have tighter rebalancing ranges
• Beliefs in momentum favor wider rebalancing ranges, whereas mean reversion encourages tighter ranges
• Illiquid investments complicate rebalancing
• Derivatives create the possibility of synthetic rebalancing
