Alger Spectra Fund Q2 2026 Portfolio Update

The performance split points to a market that is still rewarding credible AI-infrastructure cash flow while punishing “story premium” names that need continued multiple support. ALAB and WDC are the cleaner expression: both monetize real bottlenecks in the stack, so their upside tends to persist as long as capex stays strong and inventories remain tight. NBIS is more fragile — the market is likely paying for growth visibility, but that thesis is highly sensitive to utilization, financing terms, and whether customer concentration turns into pricing power or dilution.

On the loser side, GFL, QXO, and IREN all share a common problem: the market is demanding proof of self-funding. For IREN, the issue is not just execution but the path from asset-heavy infrastructure to durable ROIC; any delay in converting capacity into contracted revenue can reprice the equity hard. QXO’s roll-up model also depends on staying cheap enough to keep acquiring without compressing returns, while GFL can underperform when investors rotate away from leveraged, steady-growth compounders toward higher-beta AI beneficiaries.

The second-order effect is a portfolio-level regime shift: capital may continue migrating from “steady but visible” to “scarce capacity / AI bottleneck” names, which can help suppliers like ALAB and storage exposure like WDC even if broader growth leadership wobbles. The contrarian risk is that this trade becomes crowded; if AI capex guidance softens or a major hyperscaler pauses spend, the market will quickly differentiate between genuine picks-and-shovels and secondary beneficiaries. Watch the next 1-3 earnings cycles for order-book durability, gross margin progression, and any financing comments; that is where the move either compounds or reverses.
