EWC shorts rebuild on the month but borrow market stays relaxed

EWC, the iShares MSCI Canada ETF, heads into the final stretch of October with a contradictory short-interest picture: bearish positioning has grown sharply over the past month, yet the borrow market shows none of the stress that typically accompanies a genuine short conviction build.

The monthly rebuild in short interest is the most visible data point this week. Shares short have risen 32% over the past month to reach 5.9% of free float, and the one-week change is also notable at nearly 8%. Yet the daily figure edged back 1.1% on October 20, suggesting the build may have paused rather than accelerated. That one-month trend pulls SI to its highest level in the 30-day window of data, well above the sub-3% readings from late September, a meaningful shift in positioning for a broad passive vehicle.

The borrow market, however, tells a far more relaxed story. Availability has loosened considerably. With roughly 64.8 million shares still available to lend against fewer than 3.9 million shorted, availability sits above 1,000%, meaning there are more than ten shares available for every one currently borrowed. Borrowing costs run at 0.46% annually, down about 6% on the week, and down roughly 7.5% on the month. The 52-week low availability on record is 20%, reached at some point earlier in the year, making today's reading extraordinarily loose by comparison. Cost-to-borrow has stayed flat and cheap throughout October, barely moving between 0.43% and 0.52%. There is no squeeze pressure here, and the building short interest has not been met with any tightening in supply. That combination points to a tactical hedge rather than a high-conviction directional bet.

Options positioning is similarly unremarkable. The put/call ratio runs at 6.32, fractionally below its 20-day average of 6.35 and a z-score near zero. This is an ETF with a structurally elevated PCR, given institutional use of puts for portfolio hedging, but the ratio has actually drifted lower from readings above 7 seen through mid-September. The 52-week high touched 10.2 and the low reached 4.67, so the current level falls roughly in the middle of its annual range. Options traders are neither materially more nor less cautious than their recent baseline.

The ORTEX short score of 39.6 has been drifting in a narrow band between 38 and 41.5 for the past two weeks, offering no strong directional signal. Analyst coverage data is stale and not relevant here. Institutional ownership is dominated by BlackRock with around 41% of shares, whose Schedule 13G filing on October 5 showed the stake had grown from 19.7% to 26.1% of class. FMR (Fidelity) filed a new 13G in August disclosing a 5.8% position. Neither filing signals activist intent, and the disclosure note applies: these stakes are as last disclosed around the 5% threshold, and movements below that level may not generate further filings. The ETF continues to trade in line with Canadian equities broadly, closing at $60.87 on October 20, up about 1.6% on the week and roughly 1% on the month.

The note to watch next is whether the short-interest rebuild continues into November, and whether that accumulation eventually encounters a tighter borrow market as availability narrows from its current generous levels.
