Short positions in U.S. ETFs record biggest weekly rise since Liberation Day

Short positions in US-listed ETFs rose 8.3% in the week through March 5, the largest weekly rise since Liberation Day and the second-biggest jump in five years, per Goldman Sachs Prime Trading Desk. The uptick reflects heightened hedging and net selling across US equities for a third consecutive week, with corporate bond, energy, small-cap and large-cap equity ETFs among the most shorted. Single stocks were collectively net bought but seven of 11 sectors were net sold, driven by disposals in cyclicals and broad de-grossing in TMT, while software saw short covering.

Analysis

Large, concentrated hedging via ETFs is now an active market force rather than a background signal — the mechanical demand for borrow, delta-hedging and dealer inventory management will create amplified idiosyncratic moves in both single names and the underlying futures curve. That makes short-term dispersion trades fertile: names with acute borrow squeezes or strong fundamental catalysts can gap materially when dealers unwind hedge positions.

Energy and credit are interacting in a way that raises the probability of episodic volatility rather than a clean directional move: political tail risk (supply shocks) argues for fat-tailed upside in oil, while policy/market coordination to cap price moves (reserve releases, diplomatic pressure) acts as a structural ceiling. Simultaneously, early signs of positioning in credit ETFs imply a higher base rate for spread volatility over the next 1–3 months, which will disproportionately hurt levered credit-exposed corporates and small caps.

For technology, recent de-grossing in cyclical baskets and concentrated short-covering in software increases the odds that best-in-class AI-capex beneficiaries will outperform on any fund re-risking. Super Micro (SMCI) and AppLovin (APP) sit on opposite ends of that dynamic — SMCI benefits from immediate hardware budgets and tight supply/demand for compute, while APP is leverage to ad spend reacceleration; both are logical candidates for idiosyncratic, flow-driven rallies if ETF shorts flip to covers.

Key Decisions for Investors

• Long SMCI (tactical): Buy shares on a dip of 5–12% from current levels or initiate Jan-2027 calls 10% OTM sized for 1–2% portfolio exposure. Target 25–40% upside in 2–8 weeks if short-covering persists; hard stop at -12% or roll down into longer-dated calls if thesis remains intact.
• Long APP vs broad small-cap hedge (pair): Purchase APP shares (or 3–6 month ATM call calendar) and short IWM (or buy IWM put) sized to neutralize beta — isolate ad-tech idiosyncratic upside during re-risking windows. Expect asymmetric payoff if flows re-enter TMT; cap portfolio exposure to 1–2%.
• Volatility trade on crude: Sell a 3-month call spread on USO/XLE (expressing a capped rally) while buying a cheaper put or strangle to protect against Iran-driven spikes. Keep net premium outlay <0.5% portfolio and size to limit tail loss to 3–5% if a large supply shock occurs.
• Credit/portfolio protection: Buy 3–6 month protection via CDX IG/HY or purchase puts on HYG sized to cover 2–3% portfolio downside—cost is insurance against spread widening signaled by bond ETF positioning. This trade converts suspected ETF-driven de-risking into explicit protection at known cost.
