This framework makes alpha generation and risk management equal partners throughout portfolio construction. The team begins with both return objectives and tolerable loss characteristics, then evaluates positions through those two lenses before capital is committed. Because near-term volatility and concentration are more forecastable than returns, risk estimates help determine sizing, diversification, and acceptable exposures. The portfolio is also examined under stressful conditions so managers can precommit sensible responses rather than improvising while losses mount. The mechanism produces a more stable portfolio and reduces the likelihood that fear, forced selling, or uncontrolled rebalancing will crystallize losses. Risk specialists therefore operate inside the investment process rather than acting as police who inspect a finished portfolio and report violations afterward.
Origin
Extracted from Masters in Business, where Sandy Rattray explained the portfolio philosophy behind Strategic Risk Management and Man Group's effort to make risk part of the investment team.
Core principles
- 01Treat risk and return as equal design inputs
- 02Forecast risk where return forecasts are unreliable
- 03Prepare portfolios before stress arrives
- 04Design stability to prevent forced decisions
- 05Judge risk by investor pain, not volatility alone
How to run it
- 1
Set paired objectives
Define the desired sources of alpha alongside tolerable volatility, drawdown, liquidity, and concentration. Treat both sets of objectives as portfolio requirements.
Pro tip Express tolerances in losses decision-makers can emotionally and financially withstand.
Watch out A volatility target alone may not represent the drawdown investors actually fear.
- 2
Integrate risk expertise
Include risk specialists while ideas, instruments, and position sizes are being selected. Give them equal standing with alpha researchers.
Pro tip Review proposed trades jointly before they become embedded exposures.
Watch out Do not relegate risk review to a separate team that only inspects the completed portfolio.
- 3
Forecast measurable risks
Estimate volatility, concentration, correlations, liquidity, and scenario losses. Use these more-predictable quantities to calibrate exposure when return forecasts are weak.
Pro tip Update risk estimates frequently because volatility is serially correlated.
Watch out Do not extrapolate recent returns as if they had the same persistence as volatility.
- 4
Construct for stability
Size and diversify positions so no single exposure or market regime dominates the portfolio. Add complementary assets or strategies where needed.
Pro tip Look through asset labels to the underlying economic risk factors.
Watch out Nominally different holdings can share the same equity, technology, duration, or liquidity exposure.
- 5
Preplan stress responses
Decide in advance how the team will rebalance, reduce exposure, or maintain protection when markets become disorderly. Exercise the plan before a crisis occurs.
Pro tip Test both rapid crashes and prolonged declines.
Watch out Creating the protection plan during a drawdown is already too late.
In the wild
Rattray describes Man Group's effort to put risk specialists inside the investment team rather than having them assess a finished portfolio. Risk forecasts and alpha expectations jointly inform construction, producing portfolios intended to remain stable enough that managers do not make destructive decisions during stress.
→ Risk becomes an active source of portfolio resilience rather than a retrospective control function.
A fund combines equity alpha with government bonds and trend-following strategies. Before launch, its alpha and risk teams jointly model concentration, fast crashes, inflation shocks, and liquidity needs, then size each sleeve against a maximum tolerable drawdown.
→ The portfolio has predefined limits and responses instead of relying on improvised crisis decisions.
Common mistakes
Using risk as portfolio police
Reviewing risk only after construction prevents it from shaping exposures and encourages conflict between managers and risk specialists.
Equating volatility with investor pain
Volatility is measurable, but investors often experience risk through maximum losses and drawdowns instead.
Improvising during market stress
Managers operating without a predefined response are more likely to panic, buy continuing losers, or crystallize losses.
Is it for you?
Best for
It is best for investment teams designing diversified portfolios that must survive severe market disruptions.
Not ideal for
It is not ideal for investors unwilling to formalize risk limits or involve risk specialists in portfolio construction.
From the transcript
“In a much better way is to have the alpha side of building portfolios in the risk side to be equal partners.”
“What do you really want is as you're building the portfolios, the risk and the alphabets to to come as as equal partners.”
“It's actually much easier to forecast risk than it is to forecast returns, and you can use that to give yourself more stable portfolios.”
