Liquid Correlation Products: Index Tranches The advantage of this hedging method is that the standard indices are extremely liquid. An index hedge, however, is an average delta hedge. Index tranche trades are usually delta-hedged using the underlying index. The initial delta is conventionally traded at the same time as the index tranche. Correlation Smile, Volatility Skew and Systematic Risk Sensitivity of Tranches Alfred Hamerle, Andreas Igl and Kilian Plank University of Regensburg May 12, 2011 Abstract The classical way of treating the correlation smile phenomenon with credit index tranches is to choose a sufficiently flexible model and fit it to tranche market prices. correlation, the loss probability on the first loss piece being lower if correla-tion increases, a senior investor will be penalised if the correlation grows, as the probability of having extreme co-movements will be higher. CDO tranches are defined using the definition of attachment KA and de- plotting such correlation against the strikes one obtains a (compound) correlation smile. The market data we take as inputs, namely reference index term structure and 10y tranche spreads, are detailed in Table 1. An example of the compound correlation skew we imply from this set of market data is given below in Figure 1. Acharya and Schaefer: Correlation Products 12 Effect of Correlation – Two Assets • Suppose assets A & B both have default probabilities of 0.5 0% 25% 50% 75% 0 1 2 Number of defaults correlation = 0% correlation = 100% In credit land, correlation trading usually refers to CDO Tranches. The random events whose correlation we're measuring are corporate defaults. Most generally, the lower tranches will usually have to absorb a certain % of losses due to default, then the next senior tranches begin aborbing, and so on. Implied correlations in CDO tranches. Market quotes of CDO tranches constitute a market view on correlation at differ-ent points in the portfolio capital structure and thus on the shape of the portfolio loss distribution. We investigate different calibrations of the CreditRisk+ model to examine its ability to reproduce iTraxx tranche quotes.
Nowadays, it's often known as a bespoke tranche opportunity. Vikram Prasad Citi's managing director of Correlation and Exotics Trading—the bank offers a base correlation sensitivities are not included in the concentration risk, and the different credits within an index or basket, such as CDO tranches, are subject to price of an underlying asset or the level of an index or interest rate.)
