Credit research may be the key to navigating new risks and opportunities
For passive investors, this may represent an underappreciated shift. Exposure to the investment-grade market increasingly means exposure to a concentrated set of companies, a specific capital allocation cycle, and a single technological theme. For active managers, however, the changing market structure may create a credit selection opportunity.
Historically, credit selection has often centered on avoiding deteriorating balance sheets and identifying issuers vulnerable to economic weakness. In the case of the AI theme, a greater share of relative performance may depend on distinguishing between AI-related issuers that are allocating capital effectively and those that are not. In other words, the question is no longer simply whether hyperscalers are good credits. The question is whether the market is correctly pricing the winners and losers within a rapidly growing segment of the investment-grade universe.
As AI-related issuance becomes a larger part of benchmark indices, fundamental credit analysis may become an increasingly important source of differentiation. This may represent a meaningful shift in the forward drivers of fixed-income return. While returns of the last five years have been driven almost exclusively by interest-rate exposure, I would expect the next five to be driven more by credit exposure. When the same handful of issuers exert an outsized influence on index returns, identifying mispriced credits matters more than ever.
