Bullish Positioning Intensifies for US Large Caps as Europe Stabilises
CITI’S TAKE
Positioning rose across most regions, with the US continuing to see risk flows to large caps driving positioning into increasingly stretched territory. While legacy short exposures in the S&P 500 leave scope for further upside via covering, risk is shifting towards Nasdaq where elevated P&L is raising profit-taking risks. European flows have turned more constructive, with renewed long flows to EuroStoxx, DAX, and FTSE. However, positioning for EuroStoxx remains net short with limited conviction. In Asia, KOSPI positioning remains the most extended globally, reinforcing rising mean‑reversion risk given extreme positioning and profitability levels. China A50 has seen a steady improvement in bullish positioning, signaling selective reengagement.
US large cap bullish positioning extends, downside risk rises — US large cap positioning continues to grind higher, led by persistent new risk flows to both S&P and Nasdaq. Weekly flows were firmly in the top quartile and driven by new longs rather than covering activity. Nasdaq is extended bullish while S&P is nearing stretched levels. S&P positioning retains a sizable short base, leaving scope for further squeeze; equally, elevated P&L in Nasdaq longs raises the likelihood of profit‑taking and long liquidation on any negative catalyst.
Flows in Europe improve but EuroStoxx remains bearish — European flows turned constructive, with renewed risk flows lifting DAX and FTSE to mildly bullish levels while supporting EuroStoxx notional higher. However, aggregate EuroStoxx positioning remains moderately bearish, highlighting still-weak conviction. The key risk for EuroStoxx is the short side positioning which remains large and loss‑making, leaving the index vulnerable to a squeeze-up if positive momentum persists.
Asia: KOSPI extended bullish positioning, renewed interest in China A50 — Positioning in Asia continues to be led by KOSPI, which is currently the most extended market tracked. China A50 positioning improved and Nikkei positioning retains a long bias but has been largely unchanged in recent weeks. For KOSPI, the combination of extreme positioning and elevated P&L (mirroring Nasdaq) creates a fragile setup. While AI-linked flows continue to anchor the bull case, potential positioning saturation leaves KOSPI vulnerable to sharp unwinds.
