EWU, the iShares MSCI United Kingdom ETF, enters mid-October with a notable divergence: the options market has pulled back sharply from extreme defensive positioning even as the fund recovered only modestly from a rough month.
The most striking move this week is in options sentiment, which has swung from deeply defensive to something closer to neutral. The put/call ratio has dropped to 2.40, well below its 20-day average of 3.20 and nearly 1.2 standard deviations below that mean. That move is directionally significant: in late September, the PCR was running above 4.0, near its 52-week high of 5.57, reflecting heavy demand for downside protection on UK equity exposure. That hedging pressure has unwound materially over the past two weeks, even as the fund itself remains down 2.3% on the month and trades at $46.82. The one-week gain of just under 1% looks like stabilisation rather than a recovery.
Short interest is a minor feature of this story, not a major one. Bearish positioning amounts to less than 1.9% of the float, a low reading by any standard for an ETF of this kind. The week-on-week move tells two different stories depending on timeframe: short interest fell roughly 19% over the past week as large positions that had been added through early October were trimmed, yet it remains about 13% above where it was a month ago. With availability extraordinarily loose at over 2,000%, and shares to borrow in the lending pool numbering in the tens of millions, there is no squeeze dynamic here. Cost to borrow has ticked up to 3.2% from 2.1% a week ago, a move worth noting but not alarming given the borrow market's ample depth.
The ORTEX short score has eased to 29.6 from a recent peak above 31, reinforcing the picture of softening bearish conviction. BlackRock, as the fund's own manager and the dominant institutional holder at roughly 37% of shares, filed an updated 13G/A in August disclosing a stake of 21.2%, down from 30.7% at its previous filing in April. This is a passive, schedule-driven disclosure rather than an activist development, and the caveat applies: positions are as last disclosed around the 5% threshold, and the picture may have shifted since August.
What to watch next is whether the PCR continues its descent toward the lower end of its 52-week range, which would suggest the hedging overhang from September has fully cleared, or whether fresh macro news out of the UK, particularly on growth data or Bank of England policy, rebuilds demand for protective puts before the ratio reaches more neutral levels.
