This book provides a comprehensive treatment of all the steps of asset allocation: detecting the market invariants; estimating the invariants' distribution; modeling the market at any horizon; defining optimality; accounting for estimation- and model-risk; including the practitioner's experience...

We introduce Dynamic Entropy Pooling, a quantitative technique to perform dynamic portfolio construction with discretionary, non-synchronous views. With Dynamic Entropy Pooling, the portfolio manager can embed in the allocation process signals with life spans ranging from minutes to years,...

We measure the contributions to risk of a set of factors, strategies, or investments, based on "Minimum-Torsion Bets", namely a set of uncorrelated factors, optimized to closely track the factors used to allocate the portfolio. We then introduce a novel definition of contributions to risk, which...

How can we report returns for a swap that has zero value? How can we perform return optimization for a zero-value long-short portfolio? By introducing a suitable "basis", it is possible to extend the definition of returns to leveraged products in such a way that performance attribution and...

The intuitive meaning of "beta" is well known to all risk and portfolio managers: the beta is the sensitivity of the return on a given asset to a given risk factor. The applications of the "beta" are manifold, from risk computation and analysis to hedging. However, the precise definition and...

We introduce "factors on demand", a modular, multi-asset-class return decomposition framework that extends beyond the standard systematic-plus-idiosyncratic approach. This framework, which rests on the conditional link between flexible bottom-up estimation factor models and flexible top-down...

While it is often argued that allocation decisions can be best expressed in terms of exposure to rewarded risk factors, as opposed to somewhat arbitrary asset class decompositions, the practical implications of this paradigm shift for the optimal design of the policy portfolio still remain...

We present “The Prayer”, a recipe of ten sequential steps for all portfolio managers, risk managers, algorithmic traders across all asset classes and all investment horizons, to model and manage the P&L distribution of their positions.For each of the ten steps of the Prayer, we introduce all...
