Three signals aligned this week on REZ, the iShares Residential and Multisector Real Estate ETF. Short positions unwound sharply. Borrow costs collapsed. Options traders loaded up on calls at the most extreme pace in months.
Short interest fell 35.5% in a single week. It now stands at just 0.32% of free float — a record low for the ETF. Over the past month, short positions have dropped 62%. There is effectively no meaningful short base left in this fund.
The borrow market reflects that retreat. Cost to borrow crashed 64% in one week to 0.29%. That is roughly a quarter of where it sat in early April, when CTB topped 1.6%. Availability has expanded sharply too — now at 943%, up 61% week-on-week. For every share currently borrowed, nearly ten more are sitting available in the lending pool. The exit door for shorts is wide open and barely used.
The clearest signal this week came from the options market. The put/call ratio hit 0.09 — nearly 2.4 standard deviations below its 20-day mean of 0.47. That is the most call-dominated positioning seen in months. For context, the 52-week high on the PCR was 3.33. The current reading of 0.09 sits near the 52-week floor.
Traders are not hedging with puts. They are buying calls. That is a decisive shift in options sentiment for a real estate ETF that spent most of April and May with a PCR hovering around 0.55.
The ORTEX short score for REZ has dropped steadily from 36.3 on May 8 to 30.4 as of May 19. Lower scores reflect diminishing short pressure. The score has fallen six points in eleven days. That is a consistent, directional move — not noise.
REZ itself closed at $91.94 on May 20, up roughly 3% over the past month.
