Earnings breadth still improving

U.S. high yield credit spreads have widened year to date, reflecting greater investor caution about perceived default risk. The move also raises concerns about possible credit contagion. However, because spread widening has been concentrated in the lowest-quality issuers rather than higher-quality issuers, we don’t anticipate broader market stress.

Higher inflation and elevated interest rates typically weigh on corporate profitability, yet corporate margins continue to climb to record highs. While that strength is evident both in the U.S. and abroad, U.S. outperformance versus Europe is now the widest on record. Stronger margins have helped contribute to better-than-expected earnings and reinforce U.S. equity leadership. The question now is whether that strength can persist?

Higher interest rates have become a frequently cited risk to corporate earnings and the economy. The conventional thinking is straightforward: when borrowing costs rise, companies face higher interest expenses, profits come under pressure, and economic growth slows. While there is truth to that relationship, the current cycle may differ from investors’ expectations.

Both the dot-com era and the rise of artificial intelligence suggest that early productivity data can understate the actual economic impact of transformative technologies. In the case of the internet, later revisions to productivity gains surpassed early estimates. The same may prove true for AI, implying stronger support for growth.
