ObjectiveRisk objectiveCANNOT be determined in isolationShould be positively correlated with return objective NOT realistic to combine low risk objective with expectations for high returns6 Questions that must be addressed to determine risk objective (can you find answers these questions in IPS?)1.How do you/should you measure risk?2.What is investors WILLINGNESS to take risk?3.What is investors ABILITY to take risk?4.How much risk is investor BOTH willing&able to bear?5.What are specific risk objectives?6.How should investor allocate risk?7Investor Objectives(Risk&Return)QUESTION 1:How do you/should you measure risk?1.Variance(or volatility)is absolute measure2.Tracking risk(tracking error)measures variability with which portfolios return tracks benchmark index return is relative

Objectives(Risk&Return)QUESTION 2:What is investors willingness to take risk?Individual investorsBehavioural&personality factors impact on individuals willingness to take on riskMay act in manner viewed as NOT rationalInstitutional investorsDetermined by investment committee use objective measures viewed as rational9Investor Objectives(Risk&Return)QUESTION 3:What is investors ability to take risk?Spending needsQUESTION:How much ST$loss would inconvenience investor?High level wealth relative to potential ST$loss enable more risk takingLong-term wealth targets or obligationsQUESTION:How much ST$loss would prevent investors from reaching long term return target?High level wealth relative to targets enable more risk takingInvestor liabilities or pseudo liabilitiesQUESTION:How much ST$lossprevent institutional investor from making legally promised payments to beneficiaries orprevent individual investor from meeting expected(required not desired)retirement spending requirements?Investors financial strengthsQUESTION:What is ability to increase level of contributions(inflows)to portfolio?Greater ability to increase level of contributions,greater ability to take more risk10Investor Objectives(Risk&Return)QUESTION 4:How much risk is investor BOTH willing&able to bear?orWhat is risk aversion or risk tolerance of investor?One issue:There may be mismatch betweenWillingness to take on risk andAbility to take riskInvestment professional needs to explain mismatch with clientWillingness to take riskAbility to take riskBelow AverageAbove AverageBelow AverageAbove AverageRisk Tolerance(t):capacity to accept riskHigh Low Risk Aversion(A):inability&unwillingness to take riskHigh Low Educate that ability to take risk is limiting factor requiring revision of return expectationsEducate that willingness is limiting factor possibly resulting in only modest return 11Investor Objectives(Risk&Return)QUESTION 5:What are specific risk objectives?Risk may be specified on relative basis or absolute basisRelative basis can be stated in objective quantitative terms “portfolio risk should be 75%market index risk”Absolute basis are often stated in subjective qualitative terms “investor has below average risk tolerance”QUESTION 6:How should investor allocate risk?After investor has determinedSpecific risk measure to utilize,andDesired level of risk that will be acceptedRisk budget is allocated to various assets classes(or assets)with goal of maximizing overall risk-adjusted return(return/risk)QUESTION:Does IPS utilized formal risk budget?QUESTION:Should IPS develop formal risk budget?12Investor Objectives(Risk&Return)RETURN ObjectiveReturn objective cannot be determined in isolation because it should be positively correlated with its risk objective.4 Questions that must be addressed to formulate return objective (Can you find answers to these questions in IPS?)1.How do you/should you measure return?2.How much return does investor say they WANT(desire)?Secondary objective3.How much return does investor NEED(must)to achieve on average?Primary objective4.What are specific return objectives?13Investor Objectives(Risk&Return)QUESTION 1:How do you/should you measure return?Normal measure is total return investment income plus price appreciationNominal return vs real return what real return is required by IPS?Pretax vs post tax returnReturn objective may be stated in termsAbsolute return Relative(to benchmark)return QUESTION2:How much return does investor say they want(stated return desired)?secondary objective14QUESTION 3:How much return does investor need to achieve on average(required return or return requirement)?primary objectiveRequired return is more stringent than stated return desired Illustration(discounting of cashflows on financial calculator):Current financial assets(outflowa/t)=1,200,000Investment horizon=18 yearsRequired income each year(inflowa/t)=25,000Wealth target(inflowa/t)=2,000,000Tax rate=35%QUESTION:Calculate before tax required returnQUESTION:Assuming there NO requirement for income of 25000/year calculate after tax required return to achieve wealth target Investor Objectives(Risk&Return)Ia/t=?=4.55n=18PV=-1200000 PMT=+25000FV=+2000000=Ia/t-2,000,000 1,200,0001()(1/18)=2.88=ib/4 4.55/(1 0.35)=7.0015Investor Objectives(Risk&Return)QUESTION 4:What are specific return objectives?Specific return objective should be measurable annual total return(income&capital appreciation)Return objective mustconsistent with risk objectivesufficient to satisfy wealth objectives or liabilitiessufficient to satisfycurrent income needs with capital appreciation to satisfy future income needs after inflation(which will preserve purchasing power)16Investor ConstraintsIn addition to Objectives(Return/Risk),investor may have constraints that impact on portfolio choiceThere are five constraints1.Liquidity requirements2.Time horizon3.Tax4.Legal&Regulatory5.Unique circumstances 17Investor Constraints1.Liquidity(at time T)Liquidity requirements(for nonrecuring event or emergency)requirement for cash in excess of new contributions at specific point in time impact investors ability to take riskLiquidity risk of asset incurring loss as result of selling less liquid asset to satisfy liquidity requirementAsset selection used to control liquidity risk of asset entire liquidity requirement should be invested in assets with little or no liquidity risk(which may earn lower total return)18Investor Constraints2.Time horizon time period associated with investment objectiveIn general,longer time horizon greater investors risk toleranceHow does length of time horizon modify investorsability to take risk?asset allocation?How does multistage time horizon constrain investors asset allocation?19Investor Constraints3 Tax tax policy affects investment decision because reduce total returns(b/t a/t,we live in after tax world)IssuesDifferent tax rates apply investment income vs capital gainsEstates taxesTaxable vs non taxable investors4 Legal&Regulatory external factors imposed by government,regulatory or oversight authorities impact decision makingLimits on concentration of holdings in debt&equityLimits on foreign investment5 Unique circumstances specific to investorEthical or social responsibility(SRI)Specifics of individual(health,dependants)Inclusion/exclusion of specific asset classes(ie currency or commodities)Investors financial knowledge 20Summary Constraints(lecture
