EWC, the iShares MSCI Canada ETF, heads into mid-October with a notable tension: short interest has climbed nearly 50% over the past month while the borrow market remains among the loosest it has been all year.
The short-interest build is the standout this week. At 6.4% of the free float, the position is not extreme on its own, but the pace of accumulation is striking. Shorts have grown almost 50% over the past month, with the daily estimate touching a recent peak of around 4.5 million shares early last week before pulling back 5% on Tuesday alone. That kind of intraday volatility in the short count is typical of ETF arbitrage flows rather than a single directional conviction trade, but the net direction over October has been firmly higher. The short score has drifted in the low-to-mid 40s, settling at 41 as of Tuesday, which sits in a broadly neutral range and does not flag anything extreme.
The borrow market, though, contradicts any squeeze narrative. Availability at roughly 1,013% of short interest means there are more than ten shares available to lend for every one currently borrowed. The 52-week low in availability was 20%, a level the fund is nowhere near. Cost to borrow has also eased over the week to 0.45%, down from a short-term high near 0.52% last Monday, and remains well within "easy borrow" territory. The lending pool is ample, and there is no pressure accumulating on the short side from a supply standpoint.
Options positioning has moved sharply away from its recent norm, and in the less defensive direction. The put/call ratio has dropped to 5.79, more than three standard deviations below its 20-day average of 6.84. That is the lowest reading in over a year, with the 52-week low at 4.67 now within reach. A falling PCR in an ETF context can reflect call-buying for upside exposure or simply put-holders rolling off, but either way the options market is less defensively positioned than it has been in months. The move stands out against a price that is only fractionally higher on the week, up 0.4% to $59.18, with a month-to-date loss of around 4.6% still sitting in the background.
On the ownership side, BlackRock amended its 13G filing on October 5, lifting its declared stake from 19.7% to 26.1%. That brings BlackRock's disclosed position to roughly 31.4 million shares, nearly 41% of the fund. FMR filed a fresh 13G in August at 5.8%. Both filings are passive schedule 13G positions, not activist 13Ds, and the disclosure caveat applies: these are as-last-filed stakes around the 5% threshold, and holders can fall below without a further filing. The BlackRock stake is a natural consequence of its role as the ETF's issuer and should be read as operational rather than a directional signal.
The price chart and positioning between them leave EWC in an ambiguous spot. Options traders have turned notably less cautious even as short interest has rebuilt to a recent high, and both of those moves have happened against a backdrop of a fund that is down roughly 5% over the past month. What to watch next is whether the short count continues to drift higher into the coming weeks or begins to unwind as the Canadian macro picture, particularly commodity prices and Bank of Canada rate signals, evolves through the rest of October.
