Given overall pressure on funding rates and falling asset markets, looks set to be a year where good governance and adaptability to external events will be crucial. Theoretical arguments show that the quantity relating the risk budget to the allocation to performance-seeking assets, known as the multiplier, should be inversely proportional to the variance of excess returns of the satellite with respect to the core portfolio.
In particular, the focus on adding value through security selection has somewhat distracted the industry from another key source of added value: In fact, casting the active view generation process within the formal framework of a dynamic risk-control strategy can be shown to be the only way to successfully implement active asset allocation decisions while ensuring the respect of risk limits. There, details are also given on how to add or correct references and citations.
In fact, an explicit analytical representation of the relationship between optimal strategies in the presence and in the absence of short-term constraints can be derived, which allows us to disentangle the impact of short-term constraints from the impact of return predictability on the optimal allocation decision.

Overall, by explicitly introducing investors’ goals, constraints and risk budgets in the design of asset allocation solutions, the asset management industry has an opportunity to evolve towards providing more value-added towards investment solutions that better fit investors’ need.

Hence, dynamic risk-controlled strategies, which typically imply a reduction to equity allocation when a drop of equity prices has led to a substantial reduction of the risk budget, have often been blamed for their pro-cyclical nature that leads to sell equity holdings in those states of the world where msrtellini markets have become particularly attractive for long-term investors believing in the presence of mean-reversion in equity risk premium.
The audit F-word Sat, 1 Dec In a nutshell, a pre-commitment to risk management allows one to adjust risk exposure in an optimal state-dependent manner, and therefore to generate the highest exposure to upside potential of PSP while respecting risk constraints.

Generally, the dynamic core-satellite framework can be extended to allow one to take into account forward-looking views if and when available, eg, views based on mean-reversion in equity returns, within the framework of a sound risk-control process.
One key practical implication of this approach, sometimes referred to as dynamic core-satellite DCS approach, is that optimal investment in a performance-seeking satellite portfolio PSP is not only a function of risk aversion, but also of risk budgets margin for error defined in terms of a distance with respect to various kinds of floor levels of wealthas well as probability of the risk budget to be spent before horizon.
Given the difficulty in delivering added-value through security selection only, the old paradigm has been questioned. Putting it differently, without the performance cap, investors have a better chance of failing an almost-reached goal when their wealth level is very high.
Lioenl opposed to taking a constant multiplier value, as is typically done in base case examples of implementation, one marrtellini show that significant value can be added by making the multiplier a suitably-defined function of the forecasted level of tracking error between the core and satellite portfolios. In the past, investment banks have been at ease with dynamic asset allocation techniques, but have typically applied them to inefficient underlying assets typically market cap weighted indiceswithout any systematic effort to design optimal payoffs.
The goal-directed strategies recognise that the investor has no utility over a ceiling target level of wealth, which represents the investor’s goal actually a capwhich can be a constant, deterministic or stochastic function of time. Today, the industry is witnessing a shift in perceived added-value – there is an emerging consensus about the need to move away from stand-alone asset management products towards risk and asset management solutions that can address investors’ needs through customised dynamic asset allocation strategies.
