The data base of these loans may not classify them by their riskiness, nor even by their term to maturity. Or–to give a second example–a bank may have offsetting positions in for- eign currencies at different branches in different loca- tions. A long position in Deutschmarks in New ...
or weights in each individual asset in the asset universe. The convention is to specify portfolios in terms of weights, although the portfolio optimization tools work with holdings as well. For information about Conditional Value-at-Risk (CVaR) portfolio optimization, seePortfolio Optimization Theory....
Or–to give a second example–a bank may have offsetting positions in foreign currencies at different branches in different locations. A long position in Deutschmarks in New York may be offset by a short position in Deutschmarks in Geneva; the bank’s risk–which we intend to measure by ...
This example shows how to estimate the value at risk (VaR) for a portfolio of US Treasury bonds by using both the historical and filtered historical VaR methods. While this example uses treasury bonds as a typical asset type, you can apply this workflow to any fixed-rate bond with similar...
ValueAtRisk = portvrisk(___,RiskThreshold,PortValue) Description ValueAtRisk= portvrisk(PortReturn,PortRisk)returns the maximum potential loss in the value of a portfolio over one period of time (that is, monthly, quarterly, yearly, and so on) given the loss probability level.portvriskcalc...
We will focus on the computation of the Value-at-Risk (VaR) from the perspective of the dependency structure between the risk factors. Apart from historical simulation, most VaR methods assume a multivariate normal distribution of the risk factors. Therefore, the dependence structure between differen...
