2. Back to basics…
Typical current process:
• Selecting asset classes (i.e. which «beta» to invest in)
• Allocation (strategic mix) to these asset classes
• Active management
Tactical allocation Active management
(alpha)
Security selection
Portfolio construction
Asset Allocation
(Beta)
Sources of return

3. Some Observations
Current process can hide some risks:
• Modeling risks
The ultimate benchmark of a pension plan is the liabilities
True investors’ objectives (i.e. absolute return, pension liabilities) often not reflected in the
decision model (relatives return vs benchmark)
• The selection of asset classes based on benchmark that are sub-optimal; thus the
resulting strategic portfolio will also be sub-optimal
• Some assets classes serve to hedge a liability (i.e. bonds within a pension portfolio)
and not as a return seeking asset nor to «diversified» returns volatility
• Tactical considerations often considered in setting the strategic or selecting the
market investment policy (i.e. level of rates)
“Insanity is doing the same thing, over and over again, but expecting different
results.”

- Albert Einstein
4. To keep things simple…
Bonds Equities
Alternatives
• Bonds: Traditional indices (i.e. DEX, DEX Long) hide significant embedded
uncompensated risks when not aligned with the desired liability structure
• Equities: Market Cap based indices forced investors into risky exposure and significant
«alpha» is in fact «beta management»
• Alternatives: Typical indices are almost always not representative of the actual investment
made 4
5. Conclusion: Market indices may be simple to
use but are not meeting investors’ objectives
The fact that an opinion has been widely held is no evidence whatever that
it is not utterly absurd.
- Bertrand Russell

7. Your fixed income (FI) is not like any other
asset class
Key Messages:
Typical expected cash flow
• FI act as an offsetting position to your
liabilities
Cash Flow
• Mismatches between FI and liabilities
are typically uncompensated risks
• If FI is highly correlated with liabilities,
then it should not be seen as an asset

hedging strategy
You start with a debt, not cash (it is like being “short” a portfolio of bonds) 7

12. The risk of market-cap based benchmark
• Concentration risks (sector, region, securities)
• Momentum driven strategy (weights driven by herd mentality)
• Implicit risk positions uncontrolled over time
• Counterintuitive strategy (« Buy high, sell low »)

13. Is it true portfolio construction?
• “Macro themes” often dominate added value and/or risk profile
• Portfolio construction skill or “beta management”; example :
Value vs Growth

High dividends 35

14. Revisiting portfolio construction
What if we were ignoring published indices?
• Concept : When you prepare dinner, do you make use of everything that you
have in your pantry? Are you weighing them equally?
• Then, why not…
1) Pick the desired meal (investment/risk objectives)
2) Find the right ingredients (stock selection)
3) Follow the recipe (weight the securities to best meet the objectives)
Currently, the majority of investors are following a “recipe” proportional to the
offering in the grocery store 14
15. Smart Beta
• Heuristic-based weighting methodologies
Equally weighted (dollar)
Equally weighted (risk)
Fundamental (value, growth, multiples, profits, dividends, etc.)
Technique factors (low volatility, momentum, etc.)
Macro-economic, thematic based
RAFI index
Etc.

16. Smart Beta
• Optimization-based weighting methodologies
Maximize certain risk measures subject to constraints
Max. Sharpe ratio
Min. variance / Min-VaR
Max. diversification index

But is this only schoolbook theory? 17
18. Smart Beta
• Smart Beta strategies suffer from two main issues:
1. Highly reliant on models and parameters
2. Ignore market knowledge
• Potential consequences/risks:
High turnover
High concentration in small caps/low liquidity stocks
Heavy sector or style bias
“Any investor who strays from a weighting scheme such as capitalisation
weighting, for which the assumptions that determine the construction are
largely open to criticism and not proven, will probably take a good risk, in the
sense that there is a strong probability of doing better in the long term.”
- Smart Beta 2.0, EDHEC-Risk Institute, March 2013. 18

22. Smart Beta : From theory… to reality
• Problem # 1: highly reliant on models and parameters
Robustness: Model remains valid under different parameters and market conditions
Risk: Model and parameters are not representative of the future reality
In-sample results/choices may not be reproducible out-of-sample
Theory (ex-ante) Reality (ex-post)

23. Solutions
• Solution #1: Pick THE right model… and be right (or lucky)
Will require to change model frequently
• Solution #2: Combined models (static)
i.e.: Value + Growth; High Div + Low Vol, etc…
Risk of having offsetting models (« closet indexer ») ou that amplify the risk
• Solution #3: Multi-model approach with statistical credibility (“smart portfolio”)
Recognize that each models have a (changing) probability of being the right one and
building the most robust portfolio in any of the scenarios

27. Indices for alternatives
• Indices are typically « non investable » (i.e. real estate)
• Indices are non representative of the actual product used (i.e. hedge funds)
• Modeling process for allocation :
Breakdown asset class (or even better the actual product) into risk factor and then
assess risks diversification
• Process for manager/product selection (and monitoring) :
Absolute return / outcome approcah (i.e. benchmark or peer agnostic)
cash+x% with vol of y% on z years

the long-range risks and costs of comfortable in action."
