High yield bonds returned a robust 15.4% in the year ending June 30, extending a winning streak that produced a 56.4% cumulative return since the end of 2015. After a quick, severe drawdown at the height of the COVID-19 scare, junk bonds have experienced nearly ideal market conditions, heralding a return to trends that have been in place for several years. The post-pandemic move toward this record low has been a boon to high yield bond investors, but it has also created a significant risk of reversal. We believe most things in the financial markets are defined by cycles, with Treasury yields and credit spreads no exception. Tight readings for both rate series demand that we consider the possibility that a cyclical reversal could weigh on junk bond prices going forward.
