Dispersion

We believe we’re entering a new era of dispersion in the performance of financial assets. Behind buoyant index averages are sharply bifurcated cohorts of winners and losers. Equities are flying high but remain mostly propelled by a handful of AI superstars. Credit appears healthy in aggregate, but there’s a notable tail of unloved names. Economic growth looks robust but masks clear divergence in the experience of high- and low-income consumers, a phenomenon now termed the “k-shaped economy.” These dynamics serve as a reminder that averages shouldn’t be relied upon in a sophisticated investment process.

During the low-interest-rate environment of 2009-2021, credit was “bunched up,” with limited dispersion around the index spread. Now yields are much healthier, but a tougher backdrop (and perhaps the residual impact of the prior period being too easy) means we’re returning to a world where mistakes are punished – and potentially capitalized on. As Howard Marks recently wrote, the next phase is set to be more “interesting.”

The U.S. Economy: K-Shaped

U.S. economic data remains challenging to interpret, though the headline metrics appear mostly positive. GDP growth has certainly surprised to the upside, recording an annual rate of 4.4% in 3Q2025. Resilient consumer spending has been a big contributor, but there’s a more complex picture behind the headlines.

Aggregate consumption is reliant on a narrow cohort of high-income consumers, who’ve benefited the most from significant stock-market gains and continued to spend. (See Figure 1.) Meanwhile, the low-income consumer doesn’t look quite so buoyant. This segment benefited from strong salary growth in the wake of the pandemic, but this has now tailed off, down to 1.4% YoY compared to 4.0% for high-income households.1 Lower-income consumers have reduced their spending in several key categories, such as clothing and airlines, both categories in which high-income consumers have increased expenditure.2

Similarly, overall capital expenditure metrics have been propped up by a dramatic increase in AI-related spending. Hyperscalers’ capex is estimated to have reached around $400 billion in 2025 amid the well-publicized AI arms race.3 This represents an astonishingly high percentage of their revenue and remains complicated by a lack of clarity regarding return on investment. But right now, these companies are still soaring.
