In this paper, we propose a flexible tool to estimate the risk sensitivity of a high-dimensional portfolio composed of different classes of assets, especially in extreme risk circumstances. We build a so-called Cvine Risk Factors Model (CRFM), which is a non-linear version of a risk factor model...

The shocks on a stochastic system can be defined by means of either distribution, or variable. We relate these approaches and provide the link between the global and local effects of both types of shocks. These methodologies are used to perform stress-tests on the portfolio of financial...

The paper studies the profit distribution and portfolio management of the Swiss National Bank in comparison with the behavior of other European central banks. It is shown that the SNB's behavior is unique in a number of respects : Relatively to the countries size, it holds the largest gold...

Sharpe-like ratios have been traditionally used to measure the performances of portfolio managers. However, they suffer two intricate drawbacks (1) they are relative to a perr's performance and (2) the best score is generally assumed to correspond to a "good" portfolio allocation, with no...

This paper analyses the relationship between governance, asset allocation, and risk among state and local government-operated pension systems in the United States. It is argued that governance influences investment decisions and risk profiles of public sector pension systems, creating the...

Sharpe-like ratios have been traditionally used to measure the performances of portfolio managers. However, they are known to suffer major drawbacks. Among them, two are intricate : (1) they are relative to a peer's performance and (2) the best score is generally assumed to correspond to a...
