CDaR Multiple. Suppose we have k=1,..., K portfolio return sample-paths. For every sample-path k,  and every time moment, j=1,...J ,  portfolio drawdown = d(k,j) = maxn ((uncompounded cumulative portfolio return at time moment n on sample-path k ) - (uncompounded cumulative portfolio return at time moment j on sample-path k )). CDaR Multiple = CVaR Component Positive of the vector (d(1,1), ..., d(K,J)) = average of the largest (1-α)%  components of the vector  (d(1,1), ..., d(K,J)), where 0≤α≤1 .

 

Syntax

short call

cdarmulti_dev_name(α, matrix_1,matrix_2,...,matrix_K)

call with optional name

 

Parameters

matrix_k        is a Matrix of Scenarios:

       

where the header row contains names of variables (except scenario_probability, and scenario_benchmark). Other rows contain numerical data. The scenario_probability, and scenario_benchmark columns are optional.
