Goldman Sachs: AI Trade Crowding Peaks, H2 Rotation Toward Healthcare and European Defense
0xBroomberg
Goldman Sachs strategist Louis Miller warned on July 4 that AI-linked stocks now exceed 50% of S&P 500 concentration and momentum exposure sits at the 92nd percentile over five years, flagging healthcare and European defense as the top rotation destinations for H2.
How crowded is the AI trade right now?
Momentum-factor exposure — a measure of how heavily quant strategies are chasing recent winners — sits at the 92nd percentile over five years in Goldman's Prime Book.
AI-related stocks account for more than 50% of S&P 500 concentration. In Europe, AI weighting has doubled since 2023.
This means → too much capital is packed into one lane. Any early exit triggers a chain of forced unwinds. Momentum trades just suffered their worst two-day sell-off since 2022, with consecutive unwinding waves exceeding 5%.
Why does Goldman call July a "summer hibernation" for AI?
Seasonal patterns point to momentum trades cooling off in July, with capital shifting to the sidelines.
As Q2 earnings season begins, the market's focus will swing from narrative back to fundamentals, and stock-level divergence will widen.
In plain terms = stocks that rode the "AI story" higher in H1 now have to prove themselves with real profits.
Why is healthcare Goldman's top pick?
Goldman calls healthcare the "ultimate non-AI compounder" and ranks it as the top defensive sector for H2.
Two drivers: first, structural growth in global bioprocessing — the industrial-scale manufacturing of biologic drugs — which Goldman flags as one of its highest-conviction healthcare trades; second, the start of a large-cap pharma M&A cycle.
European pharma valuations sit roughly 10% below their historical relative-market premium. Big pharma balance sheets are flush, yet a looming patent cliff — the wave of blockbuster-drug patents expiring — makes acquisitions urgent. This means → cheap valuations + cash on hand + a need to buy — all three lines point to accelerating M&A.
Why is European defense at an inflection point from a low base?
European defense lagged in H1, but Goldman sees the recent rebound as sustainable.
Rationale: positioning is extremely light, earnings expectations have been fully reset, and depressed valuations set a very low bar for Q2 results.
Goldman estimates the sector still has roughly 12% relative upside to catch up with the broader market. In plain terms = expectations are so low that anything short of a disaster should lift prices.
Is Goldman outright bearish on AI?
No. Goldman still recommends buying the dip in US hyperscale cloud providers ahead of earnings, expecting strong Q2 EPS to push them higher.
To hedge the short-term volatility from momentum unwinds, Goldman suggests using its co-branded "ex-AI" index (SPXXAI) and the European equivalent, GSXEXXAI, as hedging tools.
This means → Goldman's stance is "don't short AI long-term, but dodge the stampede short-term" — maintain broad market exposure while stripping out the crush risk of the most crowded trades.
