AAA/AA investors are always thinking about systemic risks, and one way to reduce this risk is to minimise overlap exposure within their portfolios. The beauty of this model is that users can choose from a pool of CLO deals managed by managers they favour and optimise the portfolio for the lowest possible overlap risk based on the target number of positions they are looking to hold. Please find the download link below for the overlap optimisation model, which allows users to select from a pool of US BSL CLO deals to be added to an existing portfolio, with the model identifying the optimal outcome from an overlap perspective.

Using a sample of US BSL CLO BB bonds with reinvestment end dates between 2029 and 2031 that have been placed on BWIC since 14 April (with released trading colour), it is interesting to observe that both MVOC and manager tiering play an important role in pricing. As the loan market improves, MVOC generally strengthens, allowing BB bonds to trade at tighter levels. That said, for top-tier bonds, pricing appears to become less sensitive to further improvements in MVOC once it reaches a level of around 106.
