EWC — the iShares MSCI Canada ETF — heads into the final days of August with short interest continuing its upward march, even as the price quietly grinds to a one-month high and the lending market remains far less stressed than last week's note suggested it might become.
Short sellers have pressed harder this week. Short interest has risen nearly 20% over the past five sessions to reach 4.9% of the free float — the highest reading in the 30-day window — with around 197,000 shares added in Tuesday's session alone. That continues the rebuild flagged in the August 19 note, which caught the turn from a loose, declining trend through early August into the current upswing. At 3.2 million shares short, the absolute position is now meaningfully above the 2.4 million trough hit on August 10. The ORTEX short score has ticked up to 36.4 from 33.1 a fortnight ago, consistent with rebuilding bearish positioning, though the score remains in the lower third of the overall range — this is not an extreme short.
The contrast between rising short interest and a loosening borrow market is the interesting tension right now. Availability has actually moved in the opposite direction to short interest this week: it has expanded to 1,406%, up from 1,151% a week ago, reversing the tightening trend that was the headline story in the previous note. To put that in plain terms, there are now roughly 14 shares available to borrow for every one already lent out. Borrow costs confirm the same story — cost to borrow has nudged up about 13% on the week to 0.50%, but that is still classified as low and is materially below the 0.80% readings seen in mid-July. The 52-week availability low is 20%, so the current lending market is nowhere near stressed. Short sellers are adding positions, but they face no meaningful friction in doing so.
Options positioning adds a nuance worth noting. The put/call ratio sits at 6.99, marginally below its recent 20-day average of 6.84 — essentially in line with recent norms and well within one standard deviation. That PCR level is structurally elevated relative to the 52-week low of 4.67, but it has been running high all month and represents the baseline demand for downside protection in an ETF with a concentrated put-heavy options market rather than a sudden defensive rotation. Nothing in the options data suggests a new wave of hedging pressure this week.
Institutional ownership remains heavily concentrated. BlackRock holds roughly 25% of shares, with its position jumping by over 10 million shares in the July reporting period — a significant addition. JPMorgan and FMR together account for another 24%. That concentration means the ETF's secondary market behaviour is shaped in large part by institutional allocation decisions rather than retail sentiment, which gives the short-interest moves a slightly different character: bears are effectively trading against a broad and sticky long base.
The price itself has cooperated with neither the bull nor the bear case in dramatic fashion. EWC has gained 1.7% on the week and 6% over the past month to close at $62.64, a steady drift higher that makes the current short rebuild look more like a tactical hedge against the Canadian equity rally than a conviction-driven directional bet. The analyst data in the snapshot is over 18 years old and should be disregarded entirely.
What to watch next is whether short interest continues to build through the end of the month or plateaus — a further push toward 6% of the float would start to look more like a meaningful directional position, while a reversal would confirm the current shorts are short-term hedges unwinding alongside any pullback in Canadian equities.
