Goldman tries to explain U.S. productivity outperformance

Goldman Sachs finds U.S. labor productivity has grown an average 2.1% annually since 1995—more than double other advanced economies and creating roughly a 50% cumulative gap—driven largely by IT production and IT‑intensive sectors. The bank attributes about 0.55 percentage point of the annual U.S–Euro area productivity gap to stronger capital deepening (higher investment) and 0.35 point to faster total factor productivity (U.S. TFP ~0.95% vs Euro area ~0.6%), while measurement issues and understated hours trim the adjusted TFP gap to ~0.25 point. Goldman highlights four structural drivers—intangibles and R&D, more efficient allocation of capital and labor, superior management practices, and larger firm scale/superstar effects—with quantitative contributions cited for each factor.

Analysis

Market structure: Goldman's decomposition (U.S. labor productivity ~2.1% vs ~0.95% TFP in U.S. vs 0.6% in Euro area; ~0.25ppt adjusted annual gap) implies persistent structural winners: software, cloud, AI infrastructure and R&D-intensive professional services that capture intangible capital deepening (roughly +0.25ppt contribution). Losers are scale-constrained EU incumbents, capital-light services and commodity-centric exporters where marginal productivity gains lag; expect pricing power to concentrate in “superstar” US firms and vendors of AI hardware/software over 6–36 months.

Risk assessment: Tail risks include rapid regulatory anti‑trust/AI restrictions (25–40% downside shock to top AI incumbents in 6–12 months), a synchronized demand shock that depresses IT capex by >15% YoY, or measurement/model risk that narrows the apparent gap. Near-term (days–weeks) volatility around earnings/capex; medium-term (3–12 months) depends on AI adoption and capex cycles; long-term (2–5 years) hinges on education, migration, and policy incentives for R&D. Hidden dependency: productivity gains require skilled labor — shortages or restrictive immigration materially reduce ROI on intangible investment.

Trade implications: Favor concentrated exposure to AI/IT infra (hardware + software) and short European cyclicals/financials that underinvest in intangibles. Use option structures to express asymmetric views: buy-dated call spreads on high-volatility infra names and sell short-dated covered calls to finance carries. Cross-asset: expect stronger USD vs EUR if U.S. productivity premium persists, and upward bias in real yields/TIPS pricing over multi-year horizons.

Contrarian angles: Consensus underprices implementation risk — large-cap AI winners may see >20% drawdowns if adoption disappoints or margins compress from competition. The market may be underweight smaller, high-R&D firms (AppLovin, Super Micro) that could re-rate with AI demand; conversely, European equities may rebound if policy (R&D tax credits or M&A) narrows the gap. Historical parallel: 1990s IT investment cycles show fast re-rating followed by sharp mean reversion if capex overshoots demand.

Key Decisions for Investors

• Establish a 2% portfolio position long SMCI via a 9–12 month 20–25% OTM call spread (buy 1yr +20% OTM, sell 1yr +40% OTM) to capture AI server demand; stop-loss/exit if quarterly server bookings miss guidance by >15% or gross margin falls below 20%.
• Allocate 3% overweight to an "US intangible-heavy" basket (60% MSFT, 40% GOOGL or nearest proxies) via stock or synthetic long (bull-call spreads) with 6–18 month horizon; trim into a +15% absolute gain or if S&P outperformance vs STOXX < -5% over 30 days.
• Initiate a 1–2% short position in Euro-area equity exposure via short FEZ or buy EUR put/USD call (3–6 month) to express productivity differential; cover if ECB–Fed 2yr yield differential narrows by >50bp or Euro strengthens >3% against USD.
• Buy 3–6 month downside protection on the tech basket (purchase 6-month 10–15% OTM puts sized to cover 40–60% of net long exposure) ahead of major AI/capex earnings seasons; re-evaluate after two quarterly earnings cycles.
