KORU has completed the move its lending market was threatening — availability has dropped to exactly 0%, the lending pool is fully exhausted, and short interest has more than doubled in a week while the ETF itself lost 16%.
The borrow picture is now at its most extreme point. The previous note flagged availability collapsing back to 9.2% from a brief 75–98% window. That compression has now finished: every share in the lending pool is lent out, matching the 52-week low last touched in early July. Short interest jumped 106% on the week to reach a reported 1,637% of free float — a figure that reflects the mechanics of a 3X leveraged ETF where share creation and redemption can push estimated short positions far beyond the notional float, but the directional signal is unambiguous. Bears doubled their gross exposure in five trading days. Cost to borrow reinforced the same message, climbing to 12.6% — up 23% on the week and nearly 50% over the past month. The ORTEX short score ticked higher again to 72.8, its highest reading in the tracked window, having risen from roughly 70 earlier in July. All three lending signals — availability, cost, and short score — are pointing the same direction and all are at or near their most extreme levels of the year.
Options tell a different story, and the divergence is worth naming. Despite the ferocity of the short-side pressure in the lending market, options positioning has turned noticeably less bearish. The put/call ratio dropped to 0.73 on Friday — well below its 20-day average of 1.02 and nearly 0.9 standard deviations toward the bullish end of its recent distribution. That's a sharp shift from the ratio above 1.3 that dominated through early July, when the PCR ran at its most defensive. The move in the PCR over the past two weeks mirrors the reversal in the ETF's price direction: KORU fell 16% this week and is down 62% over the past month, closing Friday at $14.99. As the price has cratered, options traders appear to be lightening up on downside hedges rather than adding to them — either because protection has already been taken, or because call buyers are starting to probe for a bounce in Korean equities.
The macro context matters for a 3X leveraged instrument tracking South Korean markets. KORU amplifies every move in the underlying MSCI South Korea index by a factor of three, which means each percentage point of index movement becomes roughly three in the ETF. A 62% one-month decline in the ETF implies roughly a 20% drawdown in the underlying index, a move of meaningful scale for any equity market. That kind of dislocation creates the conditions where short positioning can become crowded against an instrument that, by construction, resets daily — meaning prolonged or violent reversals can accelerate decay in the opposite direction for leveraged bears.
The setup heading into next week is a genuine tension: the borrow market is at maximum tightness with no room to add new shorts through conventional lending channels, while options traders are reducing their defensive posture just as the price decline becomes most acute. Whether that options shift represents early contrarian positioning or simply reduced demand for protection after a 60% drawdown is the question the data leaves open.
