September 30, 2026: Evaluating Equity Drivers in a Higher-Rate World

We may be entering a sustained period of higher interest rates and upward inflation pressure, set against an accelerating economy. If so, the underlying drivers of equity returns could steadily shift.

When the risk-free rate sits near 5%, investors demand higher returns from equities to justify the added risk. Corporate earnings remain resilient, supported by large-scale AI investment, but higher discount rates keep valuations in check. Market multiples may not expand easily without highly durable earnings. As a result, earnings durability could become more valuable than short-term growth, particularly when rapid expansion brings elevated balance sheet risk.

With a higher cost of capital, the market may apply greater scrutiny to longer-duration equities. Speculative growth companies relying on distant profits could face headwinds, as investors show less patience for heavy capital spending without tangible, near-term profitability.

In this context, old-school investment principles become highly relevant. Companies with strong balance sheets, pricing power, and steady compounding characteristics appear better positioned. The accompanying chart illustrates this dynamic. During the 2022–2023 hiking cycle, the Quality factor, a proxy for high profitability and low leverage, recovered from an early lag to outperform the S&P 500 by the time rate hikes ended. Conversely, it lagged meaningfully as the Fed cut rates in 2024–2025. As capital becomes more expensive, a sharper focus on these fundamental qualities may offer a reliable path forward.
