Una Contribución a la Valuación de los Synthetic CDO

The Credit Default Swap (CDS) is the most popular credit derivative and it is used as an insurance against the risk of default by a particular company, known as a reference entity. If a portfolio of debt instruments is created with a complex structure where the cash flows from such portfolio are channeled to different categories of investors, we have a collateralized debt obligation (CDO). If the CDO is formed by a portfolio of CDS it is called a Synthetic CDO. The synthetic CDO transfers to market the credit risk of the portfolio. In this paper I describe the synthetic CDO valuation process and I propose an algorithm in order to get the fair price of tranches that do not require Monte Carlo simulation or Copulas, even with different notional principal values.
