The covering trend that defined EWY through September has reversed sharply, with short interest climbing back toward its recent highs just days after bears appeared to be standing down.
Short interest has rebuilt with speed. After falling roughly 26% through the month of September, shorts have added back 7.3% in the past week alone, pushing the position to nearly 21% of the free float, around 15.9 million shares. The one-month change, at 9.6%, understates how quickly the reversal has happened: most of the re-accumulation landed in the past five trading days, erasing a meaningful portion of the covering that had been the story heading into October. The previous note flagged bears in retreat; the data now says they came back.
The borrow market, however, is not flashing distress. Availability is loose, with roughly 80 million shares available against the 16 million currently borrowed, giving a ratio of about 675% of short interest. That puts lend supply well above the current short position and means new shorts can be established without meaningful friction. Cost to borrow has crept up 39% over the week to 0.34%, but in absolute terms that remains very cheap. The contrast with the 52-week low availability reading of just 0.21%, when the lending pool was essentially exhausted, is stark: there is no squeeze pressure in the current setup.
Options positioning is mildly defensive but unremarkable. The put/call ratio is running at 1.06, a touch above its 20-day average of 1.04 and only 0.2 standard deviations from the norm. That is well within the year's range of 0.22 to 2.76 and does not add a directional signal of its own. Options traders have been broadly consistent with a slight put bias all month, but the reading has actually eased from the 1.14 area seen earlier in the week, suggesting the hedging tone is not intensifying alongside the short rebuild.
The institutional holder list is worth noting for what it reveals about the composition of the short interest itself. Bank of America (10.2% of shares, adding 2.4 million in the most recent quarter) and BNP Paribas Financial Markets (6.8%, adding 2.5 million) sit at the top of the register, alongside Morgan Stanley and Citigroup, all of which added materially through June. Much of this activity is consistent with dealer hedging and structured product activity rather than directional conviction, which helps explain why borrow remains so readily available even with short interest elevated. Rafferty Asset Management, the leveraged and inverse ETF shop, also holds 4.3% of shares as of end-September, a reminder that mechanical flows tied to inverse Korea products feed into this number.
The ORTEX short score has eased to 48.9 from 53.9 a week ago, reflecting the modest unwinding at the margin, but the score's direction has been drifting lower over the past ten days even as the raw share count has risen. That divergence, between a declining score and rising short interest, is worth watching. The ETF itself closed at $183.69, down 1.5% on Wednesday but essentially flat on the week after a 2.7% pullback over the past month.
The setup to monitor is whether the short rebuild continues at pace or fades again as it did through September, and whether the currently loose borrow market begins to tighten if institutional demand for hedges on Korean equities accelerates.
