FXI, the iShares China Large-Cap ETF, enters September with its most notable story playing out in reverse: short sellers who had pushed bearish positioning to historic extremes are now quietly retreating, even as the put/call ratio drifts toward its most defensive readings of the year.
The shift in short interest is the standout this week. At 37.3% of the free float, short interest remains exceptionally high — but it has fallen nearly 10% in a single week, dropping from around 69 million shares in mid-August to roughly 62 million now. That's a meaningful unwind. The August peak, when shorts held above 70 million shares, followed a period in late July when the borrow market was essentially locked shut: availability had fallen to just 1.2% on July 22, meaning almost every share in the lending pool was already lent out. That was the tightest the borrow market had been all year. Since then, the picture has reversed sharply. Availability has loosened to 96% — still within the normal-to-tight range, but a dramatic improvement from the near-zero readings of five weeks ago. Cost to borrow has also dropped, falling 19% on the week and 38% over the past month to just 1.3%, its lowest level in the period tracked.
Options positioning tells a more cautious story than the short covering would suggest. The put/call ratio has climbed to 0.96, running about 1.6 standard deviations above its 20-day average of 0.875. That's the highest defensive reading in the recent window, with the ratio accelerating steadily over the past two weeks from the low-to-mid 0.8s. It sits well below the 52-week high of 1.23, so this is not yet an extreme, but the direction of travel is clear — options traders are buying more downside protection even as short sellers reduce their headline exposure.
The ORTEX short score sits at 68.4, a percentile ranking that places FXI comfortably in elevated-bearish territory. The score has held in a tight band between 68 and 70 for the past two weeks, suggesting the broad sentiment signal has stabilised rather than deteriorated further. On the institutional side, the most notable recent flow is Barclays adding over 6.4 million shares as of its June 30 filing, while Bank of America reduced its position by nearly 7.8 million shares over the same period. D.E. Shaw and Nearwater Capital both appear as new entrants in the Q2 data, each building positions from zero. BlackRock filed a passive Schedule 13G in July disclosing a 6.1% stake of roughly 8.7 million shares — as-last-disclosed, with no activist intent. The analyst data attached to this ticker is stale by nearly two decades and should not be treated as current.
FXI closed at $35.34 on September 1, down 0.6% on the week and 3.2% over the past month. The ETF carries no earnings catalyst of its own, but the history of sharp macro-driven moves is instructive: in April 2025, a single-day drop of 9.6% was followed by a five-day partial recovery, while the October 2025 event saw a shallower one-day dip that extended into an 8.2% five-day slide. Both episodes coincided with periods of heightened China macro sensitivity.
The setup heading into the week is one of contrasting signals: short sellers are covering, borrow conditions are easing, yet options traders are adding more hedges. Whether the short covering reflects genuine sentiment improvement or simply borrow-driven mechanics — a product of the lending pool reopening — is the question worth watching as September unfolds.
