Introduction
Risk is not always to be avoided ........
“It seems to be a law of nature, inflexible and inexorable, that those who will not risk cannot win."

Objectives • Generate ‘Libor plus’ returns; • Protect Capital.
• Risk of failing to meet strategic objectives
– Risk of losing capital:
• Downside risk.
– Risk of not meeting investment objective:
• Not achieving target value;
• Not funding a pension scheme.
• However, these risks are opposed:
• Risky investments (e.g. Equity) – generate higher return but may fall in value.
• Safe investments (e.g. Treasury Bills) – Capital is safe but returns are low.
• Balance
– ‘Risk of losing capital’ against ‘risk of generating low returns’;
– Known as the Risk vs. Reward trade-off.

Investment Strategy
Top Down Approach
• Portfolio Based
• Consider the value and return of the portfolio as a whole
• Must take into account the interrelationship between assets – Portfolio return is the weighted average of returns of the investment
– Portfolio volatility depends on the correlation between the asset returns
• Diversification – Can reduce portfolio volatility and hence reduce risk
• Using Asset Class Indices
• Weighted by Market Capitalisation
– e.g. FTSE All Share Index, FT Actuaries All Bond Index,....
• Represent overall market return
• shows average return received by all investors in that asset class
• This is called the β or ‘Beta’

Designing an Investment Strategy
Investment Strategy
• Implementing the Portfolio
• Trackers and ETF – Give pure ‘Beta’ for a very low fee
– Just give the average market return
• Funds and direct investments – Give ‘Beta’ plus α or ‘Alpha’ for a fee (typically several %)
– Paid to outperform market index
– Fund managers selected for skill in particular asset class
» e.g. Bonds, Equity, Hedge Funds, Commodities etc,
• End investor receives – Beta Layer: returns for each asset class in portfolio
– Alpha layer: returns added by fund managers minus fees
• Beta (from the asset allocation) is the largest source of Portfolio Return • Shown by academic and practical studies

Strategic Asset Allocation
Designing an Investment Strategy
• Defining an Investment Strategy
• Which asset classes and how much in each
– Asset classes to be used
– Limits on investment
• Benchmark portfolio
– Fixed allocation (e.g. Cash 5%, Bonds 45%, Equity 50%)
• Allocation ranges
– Ranges by asset class (e.g. Cash 0 to 15%, Equity 30-50% ,...)
• Purpose
• Set risk tolerance
– In terms of downside risk
• Manages return expectations
– Levels of return that can be expected
• Provide basis for performance measurement
11
Strategic Asset Allocation
Designing an Investment Strategy
Investment Strategy
• Defined as a fixed asset allocation portfolio • Typical example 5% Cash, 45% Bonds, 50% Equities
• Provide long term ‘default’ asset allocation
• Defining ‘acceptable’ levels of risk and return
• May be used as ‘safe harbour’
– when market direction not clear
– during ‘difficult times
– when manager does not have clear view
• Provide basis for performance measurement
• Simple methodology (out performance)
• Widely used (traditional)
12
Strategic Asset Allocation
Designing an Investment Strategy - Benchmark
Functions of a Benchmark Portfolio
• Analyse various benchmark architectures
• Different mixes of asset classes (e.g. Cash, Bonds, Equity, Alternatives)
• Different proportions of asset classes
• Using
• Historical back testing
• Statistical Bootstrapping
• Stochastic simulation
• Objective
• To examine behaviour in different market regimes
• Trade-off upside performance vs. downside protection

Performance
Compare Performance of Candidate Benchmarks – Traditional Plus Alternatives
– Specified as permissible range of allocation to each asset class
• Example : Cash 10 to 25%, Bonds 10 to 40%, Equity 25 to 50% ,Hedge Funds 0 to 20%, Commodity funds 0 to 10% etc ....
– Specified as permissible ranges of allocation to groups of assets
• Example: Cash + Government bonds: 10% to 50%; Equities plus Hedge funds 15% to 60% .
Generate All Feasible Asset Combinations Possible within Specified Investment Mandate
• Typically consider 100,000 possible combinations of assets
• 100,000 possible asset allocations – all permitted within investment mandate
• Use Monte-Carlo methods → randomly create feasible asset allocations

For any particular set of returns either historical or forecast
• Calculate returns available for each feasible portfolio based on historical or forecast data
• Plot distribution of returns
• Identify
– highest possible return achievable
– 75% percentile
– Mean
– 20% percentile
– Lowest possible return achievable
• Using this technique we can historically back test a set of allocation ranges
21
Strategic Asset Allocation
Designing an Investment Strategy – Allocation Ranges
Allocation Ranges
• Review how mandate would have performed historically under different market regimes
• Show most likely performance • Central two quartiles – coloured light blue
• Assess
• Upside potential of mandate – what level of returns could be achieved in good times
• Downside risk – what is risk of under performance or losing capital
• Can manager adjust asset allocation to control risk and/or increase return – Is there enough scope to increase return in good times?
– Is there scope to protect capital in bad times ?

Strategic Asset Allocation
Designing an Investment Strategy – Allocation Ranges
• During benign regime
• Positive return for all asset allocations
• Would anticipate manager would deliver performance (12-months to date) in the central box
• Note how size of performance range changes
• May ’05: 12% to 17%
• April ’06: 6% to 32%

Benchmarks
• During ‘difficult’ times
• Mandate will lead to negative returns
• Manager has opportunity reduce losses
• So we can anticipate downside risk of mandate
– under typical ‘historical’ conditions
However current conditions 2H2008 are not typical!

• During recent crisis
– Show manager could protect some but limited protection against losses
– Suggests mandate should be modified to allow more cash to be held

27
Strategic Asset Allocation
Monitoring an Investment Strategy
• Can compare actual performance with feasible performance range for investment mandate
• Provides fair measure of investment management performance
– Within mandate
– Against market conditions
– Categorise as 1st, 2nd, 3rd or 4th quartile
• Alternatively 1st, 2nd ,3rd or 4th Division performance !
• Can assess if manager is using full range of mandate
– Well: capturing upside opportunities and avoiding downside
– Badly: ignoring upsides or increasing losses

Portfolios & Benchmarks
• Measure risk relative to benchmark
– Known as Tracking Error (‘Tracking Error Variance’)
• Plot both return and volatility of returns
– Each point represents a ‘feasible portfolio’
– Resultant ‘cloud’ of points shows how return and volatility within mandate are related
• Provides measure of tracking error of actual portfolio
– Hence can distinguish
• ‘Good’ tracking error that increases return or reduces risk
• ‘Bad’ tracking error that decreases return or increases risk

• This shows the fund manager reducing risk at the expense of commensurate reduction in return

Summary
Summary
• Risk is a necessary to generate return
• Investment benchmarks and mandates can be designed to provide a balance between
• Protecting capital
• Generating return to meet objectives
• In line with long term objectives of fund
• Performance must be measured against
– Market Conditions
– Investment Mandate
