Asset Allocation Flashcards
Effective Investment Governance Models
- Express short-and long-term objectives.
- Allocate decision rights and responsibilities.
- Establish processes for developing the IPS
- Establish processes for developing and approving the SAA.
- Establish framework for reporting and monitoring progress toward objectives and goals.
- Periodically perform a governance audit.
The Extended Portfolio Assets and Liabilities
- Extended Portfolio Assets: Is the present value of future income, pension income, intellectual property, royalties, inheritance, and minerals or resources
- Extended Liabilities: The expected present value of future expected consumption or payouts
Human Capital vs Financial Capital due to Age
- When individual is younger human capital is high, financial capital is low
- When individual is older human capital is low, financial capital is high
Types of Asset Allocation Approaches
- Asset-Only Approach
- Liability-Relative Based
- Goals Based
Asset Only (AO)
- Making asset allocation decision based only on the investor’s assets on the balance sheet.
- Liabilities are not modeled.
- Relevant Risk Measures: The volaility and corelations of the portolfio returns.
Liability Relative
- Accounts for the liability-side of the balance sheet
- Mainly for institution investors, but can be used by individual investors
- Designed to create allocation decisions for when a liability comes due
- Relevant Risk Measures: Not having enough assets in the portfolio when the liabilities come due
Goals Based
- Asset allocation to sub-portfolio (mostly individuals).
- Common goals are retirement, college, charitable gifts, life-style expenses
- Each sub-portfolio will have its own unique asset allocation to meet a specific goal
- The sum of the sub-portfolios is the Strategic Asset Allocation (SAA)
- Potential risk not being able to meet or achieve the investor goal(s)
- Portfolio risk will be a weighted-average of each having its own probabilities associated with them
What Constitutes an Asset-Class
- Homogenous: The asset should have similar attributes from a descriptive and statical perspective
- Mutually Exclusive: Asset cannot be classified in more than one asset class
- Diversification: An asset class should not be highly correlated
- Asset Classes should cover all possible investable assets as a group and should make up a preponderance of the world investable wealth
- Asset classes should contain a sufficiently large amount of liquid assets that has the capacity to absorb a significant fraction of an investor’s portfolio without seriously affecting the liquidity
Strategic Asset Allocation (SAA)
The long-term strategic plan
Has to be Based on:
* Objectives
* Constraints
Tactical Asset Allocation (TAA)
Is an active management strategy that uses a specific sub-asset class short-term deviation to exploit a specific opportunity in the market
Key Issues: cost benefit approach
* Need to incur additional trading and monitoring cost
* May incur capital gains taxes
9 Steps Needed to Select a SAA
- Determine investors objectives, goals, what are they trying to achieve
- Determine the investors risk tolerance
- What is the investment horizon to be used to measure an investors risk requirement and tolerance
- What is the investor tax situation and/or constraints
- Select the asset allocation approach appropriate for the investor
- Specify the asset classes determine the CME
- Develop the potential asset allocation for the investor to consider
- Simulate the results to see if they meet the needs of the client
- Continue until the optimal allocation is determine
Note:
* It needs to monitored regularly to make sure it’s consistent with the client’s IPS.
* Any change in the long-term are incorporated back into the model for potential revision.
Global Market Portfolio
- Represents a highly diversified asset allocation
- Serves as a baseline in an asset-only approach.
- Reflects the supply and demand across world markets.
- Investors can invest in a risk-free asset, a risky asset, and a combination between
- Once we institute the risk-free asset into the efficient frontier there will no longer be a curve linear anchor at the risk-free rate of return
- We can create capital allocation lines series anchored at the risk-free rate, then cut the original efficient frontier at different points
- The slope of any capital allocation line would be the Sharpe ratio
- Market portfolio: The highest part of the line tangent to the efficient frontier
Types of Strategic Choices
- Indexing: Low costs, with some transaction costs (buy/sell, called, defaults). Follows a passive strategy.
- Enhanced Indexing: Cell matching primary risks factors but with fewer securities (in numbers)
- Full Active: Tracking error will increase, but also expected active return, can outperform the index
Strategic Implement Choice
- Available investments.
- Scalability of active strategies.
- The feasibility of investing passively while incorporating client-specific constraints.
- Beliefs concerning market informational efficiency.
- The trade-off of benefits relative to costs and risks of active investing.
- The management costs, trading costs, and turnover-induced taxes in active investing
- Tax status
Rebalancing
May be necessary under 2 conditions:
* Changes to the policy portfolio because of changes in an investor’s investment objectives and constraints, or in long-term capital market expectations.
* Adjusting the actual portfolio to the SAA because asset price changes have moved portfolio weights away from the target weights beyond tolerance limits.
Rebalancing Approaches
- Calendar-based: Rebalances the portfolio to target weights on a periodic basis, such as quarterly.
- Range-based: Sets rebalancing thresholds (trigger points) around target weights.
Corridor
“Rebalancing Range”
Wider:
* Transaction Costs
* Risk Tolerance
* Correlations with the rest of the portfolio
Narrower:
* Greater volatility
* Correlation
* Risk tolerance
Mean Variance Optimization (MVO)
- Single period framework on the efficient frontier
- The objective is to maximize the return for a unit of risk (Sharpe Raito, MVO)
- Issues: might not be the best for multi-period rebalancing issues
- Does not take into account the liability approach
- Assume investors are risk adverse.
- Can be complemented it with Monte Carlo Simulation (MCS)
- A portfolio manager can start by using MVO and then use MCS to generate many different paths overtime
- MVO can lead to concentration portfolio with zero allocation to certain asset classes
Efficient Frontier
- Curvy-Linear, should include all risky assets, but not the risk-free asset
- All portfolios on the line are considered efficient
- All analyst is based on the investor’s constraints
- To find the optimal point is to find the investors indifference direct (utility curves)
What are Some of the Criticisms of MVO
- Garbage-In; Garbage-Out (GIGO): MVO is really sensitive to the inputs used
- Any portfolio on the efficient frontier is an efficient, but that portfolio is not a well-diversified portfolio
- Assumes all portfolios are normally distributed; it does not take into account skewness & kurtosis and portfolios that’s are not normally distributed
- Risk Diversification: Not diversified by the sources of risk (risk factors)
- Ignores liabilities
- Operates in a single period framework.
It doesn’t take into account:
* Interim cash flow
* Serial correlation of assets returns from one period to the next
* Rebalancing
* Taxes
Black-Litterman Model
Estimation Error Specifically
* Fixes the problem with expected return and high sensitivity of MVO
* Allows for short-selling and negative inputs
* Takes into account the portfolio manager views which can adjust the portfolio
* Reserve optimization whereby MVO and the portfolio managers views are put together
* Can be used to calculate the market consensus expectations of returns
Items to Consider:
* Less sensitive to change in inputs
* Less likely to produce asset class concentration
Resample MVO
- The major drawback to the efficient frontier is the sensitivity to any change in the inputs
- Simulation Approach: Using historical metrics and combined them with the CME
- This technique is a Monte Carlo Simulation (MCS).
- Will not be a smooth shape curve
- Levels above and below will have a distribution of different portfolios with different asset classes
- No single exact portfolio that will be optional, any average will be more stable than just one
Advantage and Disadvantages of Resample MVO to Regular MVO
Advantage:
* Uses an average period creates an efficient frontier that is a lot more stable
* Better diversified than regular MVO which can have concentrated positions
* Can have an existing portfolio to see if the asset mix is within the range and is acceptable
Disadvantages:
1. Lacks sounds theoretical basis, there is no reason to say that an average will be better
2. A lot of the inputs are based on historical data which, can be lacking.
Monte Carlo Simulation (MCS)
- Simulations will be ran 1000s of times and creates efficient portfolios at each different level of returns
- To address the limitations of MVO as a single period model and incorporate rebalancing and taxes in a multiperiod framework
- Try to explain the likelihood of an outcome to see what are the possibilities.
