A convergence report published earlier today covered Morgan Stanley's dramatic flip to Underweight on RIO. Since then, a separate signal has landed: the borrow market has swung decisively in the opposite direction from where short sentiment sits.
Cost to borrow collapsed 88.6% in a single week — from 0.41% to 0.047%. Availability has surged to 1,222%, up 191% week-on-week. That means roughly 12 shares are now available for every one already borrowed. The lending pool has opened up sharply, even as the stock trades 16% higher over the past month.
That combination is unusual. When a stock rallies hard, borrow availability typically tightens as short sellers hunt for capacity. Here, the opposite has happened. Shorts covered. Short interest fell 23% over the past month — around 2.4 million fewer shares short today than in late July. Those closures freed up inventory, and lenders flooded the pool with fresh supply.
The result: borrowing RIO is now nearly free. At 0.047%, the cost to borrow sits at the lowest level in at least 30 days.
The borrow market says shorts are retreating. The options market says hedgers are still nervous.
The put-call ratio closed at 0.85 on August 21 — above the 20-day mean of 0.75, and elevated relative to the prior month's range. PCR has stayed above 0.84 every day since August 14. Before that, it had not breached 0.74 since July. The shift is clear and sustained.
Morgan Stanley set a $90 target this morning. The stock closed at $105.30 on August 21. That 14.5% gap gives options hedgers a concrete downside level to position around. Put demand rising in lockstep with analyst caution is a coherent pattern.
Two forces are now pulling in different directions on the short trade. The borrow market says the position has been unwound — availability is loose, cost is negligible, and short interest has dropped materially. But options positioning suggests participants are still paying for downside protection, not abandoning it.
Earnings are next scheduled for October 14. Between now and then, the tension between a relaxed lending market and elevated put demand will tell you which camp — the covering shorts or the hedging longs — is reading this rally correctly.
