AI Capex Cycle Splits Winners From Margin Casualties As Earnings Season Grinds On

The AI trade is no longer monolithic. Capital is migrating decisively toward the electrification and thermal-management layer of the buildout, where pricing power is structural and backlogs are contractual. GE Vernova's upgrade rests on a pattern investors reward above almost anything else: guidance raised every quarter, with a 2028 setup that implies the power-demand cycle is longer than the current order book suggests. Woodward is being positioned similarly, straddling aerospace aftermarket strength and grid-adjacent turbine demand. Contrast that with Super Micro Computer, which again posted respectable topline expansion while gross margin behaved erratically, the recurring signature of a business that assembles rather than differentiates. The upcoming Cerebras report, and what chief executive Andrew Feldman signals on customer concentration and capacity, becomes a live referendum on whether challenger silicon can command durable pricing against incumbent accelerators. Meanwhile the perennial capital-allocation debate persists between AMD's momentum-and-balance-sheet profile and Alphabet's discounted cash-generation case. Our conclusion for institutional portfolios: prefer the bottleneck over the box. Power, turbines, cooling and precision components are where AI demand converts into defensible margin.
