Current Policy Portfolio Shaped by History Investments
Over the past several decades pension systems have
targeted absolute returns at +/- 8%
Given declining bond yields, this led to an overweighting of
equities...
...steadily increasing the absolute risk levels of pension
assets...
...resulting in policy portfolios that perform well primarily in
high growth/low inflation environments [e.g. the 1990s]

Actuarial investment rates of 8% unachievable with current
policy portfolio, atleast for next 5+ year period
We must also understand 'normal' portfolio returns in 30 year
period [long term] independent of cyclical valuation anomalies
Long term balanced policy portfolio should be built using normal
returns
Short term policy portfolio must begin transition towards long
term portfolio, adjusted for cyclical- valuation opportunities

In the last decade, asset diversification tailed just when it was
most needed
Failure of markets or ailure of assumptions?
•Model risk: Over-reliance on mean-variance analysis as the primary
tool to model potential outcomes:
Volatility higher than forecasted
,Downside risk in 'tail' events underestimated
Markets failed to realize 'mean return expectations'
Amid stress, 'normal' correlations among assets soared

Risk Budgeting
Consider the portfolio from a total risk perspective rather than total
return
An attempt to determine the contribution to risk by each asset class in
the portfolio, based on
• Asset class volatility assumptions
• Correlations between asset classes
Shows the benefit of diversification
• But also the risk exposures in relation to allocation size
Especially useful if asset classes are bucketed by
• Role they play in total portfolio
• Risk similarity

Asset Allocation Tools: Mean-Variance Analysis Investments
Limits to the use of mean/variance analysis
■ Expected return, standard deviation and correlation are critical estimates
but notoriously unreliable
r Recent markets have violated fundamental assumptions behind this investment tool
r Mean/variance analysis works best for liquid assets in liquid markets
Expected return is expected to be optimistic (too high) 50% of the time
One standard deviation around expected return covers only 2/3 of the estimate, and
two standard deviations is not a great measure of how bad things can get
Correlations are inherently unstable and in down markets soar to 1.0 for similar risk
assets
Correlations can show diversification benefits of alternative investments, but is not
precise enough to determine sizing
