FXI, the iShares China Large-Cap ETF, ends the week with bears in partial retreat — short interest has fallen from last week's highs, the borrow market has loosened further, and the ETF itself has nudged higher — yet the underlying positioning remains among the most extreme in the market.
The reversal in shorts is the clearest data point this week. Last week's note flagged a sharp rebuild in short interest, which had climbed to around 65 million shares and 39% of free float. That build has now partially unwound. Short interest has trimmed to 63.4 million shares, roughly 38% of free float — down just under 3% on the week. That's still a massive directional short against Chinese large-caps, but the direction of travel has flipped: bears added aggressively through the first two weeks of September and are now trimming back. Over the past month, short interest is down more than 10%, consistent with a slow bleed of conviction from the peak levels seen in mid-August, when shorts topped 70 million shares.
The borrow market reinforces the picture of easing rather than tightening pressure. Availability has moved to 154.6% — meaning roughly 1.5 shares remain lendable for every share already borrowed — up from around 133% a week ago and considerably looser than the levels seen in August, when availability dipped toward 60-70%. The 52-week low for availability was a striking 0.26%, a point of near-total lock-up that now looks like a distant memory. Cost to borrow has also softened, falling to 1.14% from above 1.9% in mid-August. The combination of rising availability and falling borrowing costs tells a consistent story: the demand pressure from short sellers is easing, not building. Options positioning is only mildly defensive — the put/call ratio is 0.954, just above its 20-day average of 0.932, with a z-score below 1. That's barely a signal, and nowhere near the hedging intensity that would suggest institutional alarm.
The ORTEX short score is running at 66.6, a moderately elevated reading that reflects the still-high absolute level of short interest rather than an accelerating bear campaign. The score has been range-bound between 65 and 69 over the past two weeks, consistent with positioning that is heavy but no longer directionally driven. Analyst data on FXI is stale — the most recent price target in the database dates back nearly two decades — so the Street view is not a meaningful input here. What is visible in the institutional register is that Barclays added over 6.4 million shares in Q2, BNP Paribas added 3.8 million, and D.E. Shaw entered with a fresh position of just over 4 million shares — all as of June 30. Those are meaningful additions from institutional names that often run paired structures (long ETF, short single names or futures), so the net directional read is ambiguous. BlackRock filed a passive 13G disclosing a 6.1% stake in July 2026, consistent with their role as the ETF's parent and not a signal of external accumulation.
The narrative has shifted materially since last week's note flagged a sharp short rebuild and split sentiment. That split has partially resolved: the short camp is trimming, the borrow market is easier, and the ETF has gained 1.7% on the week to $35.00. What remains unresolved is whether the still-high 38% short interest reflects a durable macro thesis on Chinese large-caps — policy drag, geopolitical risk, domestic demand weakness — or an overcrowded position that continues to bleed. With availability comfortable and borrowing costs low, the mechanical conditions for a squeeze are not present; but the sheer scale of the short base means any shift in sentiment toward China would face a significant wall of covering demand to work through.
The key variables to watch are any macro signals out of Beijing — stimulus announcements, property sector data, or trade developments — that could catalyse covering flows, and whether the slow month-long unwind in short interest accelerates or stalls heading into October.
