Why this matters: The lending market for FPX, the First Trust US Equity Opportunities ETF, has shifted dramatically in just weeks. Borrowed shares have tripled in a month. Borrow costs have doubled in a week. Availability is tightening fast — and this is happening on an ETF where shorting activity was nearly invisible just 30 days ago.
The standout here is speed. On August 17, availability sat above 2,000% — meaning roughly 20 shares were available for every one already borrowed. As of September 17, availability has collapsed to 280%. That is still within normal range, but the direction is unambiguous.
In the same period, the borrow rate nearly doubled in a week alone. Cost to borrow moved from 1.23% on September 10 to 2.51% by September 17 — a 104% jump in seven trading days.
Short shares themselves are up 205% over the past month. The absolute level remains small: just 0.35% of free float. But the rate of change is what the lending market is pricing.
The proportion of available shares being lent out hit 94.4% on September 17. That is the highest reading in 52 weeks. The 52-week peak utilization stands at 100%, so the pool is not yet fully drawn. But the trajectory from 16.6% on August 21 to 94.4% in under four weeks marks an aggressive demand surge by the standards of this fund.
For an ETF with minimal historical shorting activity, that pace is notable. ETFs generally have deep, liquid lending pools. When one tightens this quickly, it typically signals a specific tactical trade — hedging, pair positioning, or directional pressure on the underlying basket — rather than broad market pessimism.
FPX closed at $177.73 on September 17, down 8.2% over the past month. The ORTEX short score stands at 46.7 — up from 38.2 on September 7, its fastest 10-day move in the available history. The score has not reached extreme territory, but the trend mirrors the borrow market: a clear inflection from mid-August.
Options positioning remains calm. The put/call ratio sits at 0.25, near its 20-day average. No unusual options activity corroborates the shorting signal.
