With interest rates rising, do you think now is a good time to invest in equities?
Robust corporate earnings have supported global equity markets despite 10-year US Treasury yields reaching 5.30 percent. Strong performance in US and European sectors suggests that operational gains are currently offsetting the higher cost of capital.
Why it matters
Productivity gains from internal AI agent integration and infrastructure spending are driving profit growth, allowing firms to navigate a high-interest-rate environment. These shifts indicate that operators leveraging automation and specialized industrial focus are best positioned for continued expansion.
US corporate profit growth reached 30% alongside a 16% net profit margin for S&P 500 companies, while the Russell 2000 gained over 13% year-over-year. Future activity includes a projected $300 billion in 2026 secondary market deal volume and €584 billion in European grid investment through 2030.
The players
Luxembourg Investment Forum
An international platform for institutional investors and financiers to discuss global macroeconomic trends and sector-specific asset allocation.
The details
Companies are maintaining margins by deploying internal AI agents to automate core workflows, while private equity managers pivot toward intensive operational improvements. Simultaneously, structural reindustrialization and energy independence goals are creating high-demand niches in defense and power infrastructure. This combination of efficiency-focused tech adoption and capital-intensive infrastructure projects has allowed businesses to sustain growth despite the 5.30% benchmark yield.
Timeline
Defence equities grew 230 percent between 2022 and mid-2026.
The Luxembourg Investment Forum held a panel discussion on October 7, 2026.
Secondary market deal volume is projected to approach 300 billion dollars in 2026.
US small-cap earnings are forecast to grow over 40 percent in 2027.
European electricity grid investments are required through 2030.
Market Landscape
This earnings performance follows a pattern set by recent large-scale infrastructure investments, mirroring the systematic capital deployment seen in the Inflation Reduction Act's infrastructure spending provisions. The current focus marks a departure from purely service-led growth toward a heavy emphasis on sovereignty sectors like defense and power.
Operators should evaluate how their current AI automation strategies compare to industry profit margin benchmarks like the 16% seen in the S&P 500. Additionally, consider if your firm can capitalize on emerging demand in infrastructure-related sectors as European grid investments accelerate.
The takeaway
Current market conditions favor businesses that use automation to defend margins against elevated borrowing costs. Monitor the 40 percent growth forecast for small-caps in 2027 as a key indicator of whether this momentum will broaden beyond large-cap incumbents.
