KSA, the iShares MSCI Saudi Arabia ETF, enters the final days of August with an unusual split: short sellers pulling back sharply even as options positioning shifts more bullish than it has been in months.
The most striking move this week is in short interest. Bears have cut positions hard — SI fell roughly 13% in a single session on August 25, bringing the total short position down 15% on the week to 29.7% of the free float. That's still an elevated absolute level, but the direction of travel has changed noticeably. A month ago shorts were running near 30.5% of float; the peak in mid-August touched above 32%. The pullback coincides cleanly with the ETF's 3.2% weekly gain and a 5.9% rise over the past month, now closing at $39.26. Short sellers who piled in above $37 are facing losses, and the evidence suggests at least partial covering rather than a new-conviction short build.
The borrow market tells a complementary story. Cost to borrow has eased considerably, falling nearly 20% on the week to 2.35% — a level that, while modest in absolute terms, is back near the low end of the past 30-day range after hitting 3.18% earlier this month. Availability sits at 58%, meaning there are roughly 0.58 shares available to borrow for every share already shorted. That's on the tighter end of a normal range — notably, the 52-week tightest reading was 5.9% — but the lending market isn't flashing distress. Shorts who want to cover can exit; new shorts remain somewhat constrained but not squeezed.
The sharpest repricing this week is in options. The put/call ratio has dropped to 1.15, nearly 2.5 standard deviations below its 20-day average of 1.49. That is the most bullish options posture for KSA in weeks, and it marks a decisive break from the deeply defensive pattern that held through July and early August when the PCR was consistently running above 1.6. That shift in options sentiment — away from put-heavy protection and toward calls — lines up precisely with the covering in short interest. The two signals together point to a broad repositioning, with both options traders and short sellers reducing bearish bets into the rally.
The ORTEX short score, while still elevated at 81, has ticked down from its recent peak near 83. The score remains high — reflecting the still-meaningful 29.7% short interest level — but the direction is clearly softening. That combination of high absolute short positioning with a declining score and falling SI is the profile of a slow unwind rather than a panic cover.
What to watch next is whether short interest stabilises around current levels or continues its descent — a further meaningful drop below 25% of float would represent a materially less contested position, and how quickly the borrow cost and availability respond will indicate whether the remaining shorts are becoming more or less comfortable holding.
