RSP, the Invesco S&P 500 Equal Weight ETF, enters mid-May with a clear directional shift: short sellers who piled in during the April volatility spike are now quietly covering, even as broader put hedging demand stays structurally elevated.
The unwinding in shorts is the most immediate story. Short interest dropped 14% over the past week, falling to roughly 7.25% of free float from a recent peak near 8.5% on May 4. That peak was itself the highest level in the 30-day window. The retreat since then has been steady — five consecutive sessions of lower short positions — and it coincides with RSP climbing 3.6% over the past month to close at $203.81 on May 12. Borrow conditions have not tightened enough to force the covering: cost to borrow is running at just 0.70% annualised, still modest even after rising 71% from its early-April lows. Availability is ample, with lending utilisation at 36% against a 52-week high of 63%, leaving plenty of room in the borrow pool for new shorts to enter if sentiment shifts.
Options tell a structurally more cautious story, even after the worst of the fear has passed. The put/call ratio hit a 52-week high of 3.06 on April 30 — during the sharpest phase of trade-war anxiety — and has since pulled back to 2.32. That is still well above the 52-week low of 0.73 and running above the 20-day mean of 2.20. The practical interpretation: options traders are still buying more than twice as many puts as calls on RSP, but the most defensive positioning of the cycle has eased meaningfully over the past two weeks. The z-score of 0.30 confirms the current reading is only marginally above the recent average — not stretched, but tilted protective.
The ORTEX short score of 53.6 reflects a genuinely mixed picture. It has fallen from 57.4 on May 4, tracking the SI decline, but remains above the 50-line that separates cautious-but-balanced from outright short-pressure territory. That arc — sharp spike then steady retreat — is consistent with tactical hedges being lifted rather than a fundamental shift in how investors view equal-weight exposure.
On the institutional side, Morgan Stanley is the largest reported holder at roughly 7.9% of shares, followed by Northwestern Mutual at 7.0% and Goldman Sachs steady at 3.0% with no reported change through March 31. The Goldman flat-line is a minor data point, but the fact that no major holder shows an aggressive reduction through Q1 supports the picture of institutional ownership as a stable base rather than a source of selling pressure.
What to watch from here: RSP's short interest has been oscillating in a clear range — spiking toward 8–8.5% of float during macro stress events and retracing toward 7% when sentiment stabilises. Whether the current 7.25% level represents a floor or a transit point lower depends entirely on whether the macro backdrop that drove the April hedging wave reasserts itself.
