Capital Expenditure Inelasticity: Decoupling Returns in a 5% Yield Regime

on

 


When the 10-year US Treasury yield breaches 5.0%, conventional equity valuation models crack. In September, our portfolio decoupled entirely from index beta, generating an +11.71% return (+1,132 basis points of relative alpha against the S&P 500) and extending our return versus January 2024 to +126.48%.

In classical financial theory, rising risk-free yields lift hurdle rates across discounted cash flow models, penalizing long-duration assets and forcing cyclical enterprises to curtail capital spending. For broad indices, this transmission mechanism is toxic. Following a 25-basis-point Federal Reserve policy hike, the S&P 500 stalled at +0.39%, held down by constituents facing borrowing pressure and margin contraction.

Our outperformance is driven by the microeconomics of compute rationing, specifically CapEx Inelasticity.

Broad market indices assume corporate capital spending functions elastically relative to borrowing costs. In frontier compute architectures, that elastic relationship collapses. Hyperscalers (Alphabet, Amazon, Microsoft) are locked in an existential platform transition. Under-allocating capital to computing clusters guarantees the permanent loss of platform dominance. As a result, hyperscaler infrastructure spending exhibits near-zero price elasticity of demand.

Regardless of whether capital costs sit at 2% or 5%, physical hardware must be procured at scale. Because compute demand is price-inelastic, rising interest rates cannot force price concessions from physical bottlenecks.

Capital concentrates where absolute barriers to entry prevent substitution:

  1. Lithography: Foundries cannot substitute toolsets from ASML or KLA to offset interest expenses.

  2. Accelerator Architecture: Output from NVIDIA and AMD dictates cluster throughput, leaving pricing power entirely with the supplier.

  3. Interconnect Fabric: Custom silicon from Broadcom and Marvell scales directly with cluster size.

Rather than absorbing higher rates, these structural monopolies extract economic rents directly from buyers' cash balances.

We do not hedge against interest rates by buying defensive, low-margin utilities. We insulate capital by owning structural monopolies.
