The audit F-word Sat, 1 Dec 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 lionl implement active asset allocation decisions while ensuring the respect of risk limits.

In the past, investment banks have been at ease with dynamic asset allocation techniques, but have typically applied them to inefficient maartellini assets typically market cap weighted indiceswithout any systematic effort to design optimal payoffs.

Using a parsimonious GARCH model with a Student-t distribution fatter tails for the independent and identically distributed random shocks that accounts for the presence of autocorrelation, heteroskedasticity and asymmetry leverage effectand re-estimating the model parameters using a growing window sample to estimate the next period variance, we generate forward-looking estimates of tracking error levels, and used these forecasts to dynamically adjust the multiplier values.

On the other hand, in a slowly-rising bull market and in all bear market environments, the strategy with time-varying multiplier value would perform better and it reacts fast enough to reversions due to the related increase in volatility.

Using a strategy with time-varying multiplier value allows for substantial increase in mean returns, as well as a decrease in risk parameters relative to the benchmark case with constant parameter values.

Country Reports Nordic Region: Working papers Sorry, no citations of working papers recorded. Currency returns to the fore Sat, 1 Dec German Longevity: Given the difficulty in delivering added-value through security selection only, the old paradigm has been questioned. This stands in sharp contrast to fix-mix strategies, where the target allocation to the PSP is constant over time, regardless of the distance with respect to the investors’ goals and constraints.

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.

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 equity markets have become particularly attractive for long-term investors believing in the presence of mean-reversion in equity risk premium.

Rethinking auto-enrolment Thu, 1 Nov Benchmarking: As opposed to taking a constant multiplier value, as is typically done in base case examples of implementation, one can 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.

Berkeley and at Princeton University, where he has been a visiting fellow at the Operations Research and Financial Engineering department.

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.
