摘要

In this paper we propose a speeding up method of needsbasedCDO (Collateralized Debt Obligation), which meets investor needs of attributes of CDO. We note the fact that the computing time to derive the best CDO is proportional to the number of candidates of the best CDO which are generated of portfolio by changing contract conditions in a certain band.Elucidating the relationship between the change of contract condition and the objective function analytically, and grouping candidates that have the same merchantability observed from the standpoint of investors, we reduces redundant generation of the candidates. The comparative experiment indicates that the proposed method makes it possible to double the kinds of tranches or to rise the calculation accuracy nearly sixfold keeping immediacy of calculation.
