FNGS, the MicroSectors FANG+ ETN, has become meaningfully more crowded on the short side in recent weeks, a sharp shift for an instrument that saw almost no bearish positioning through most of August.
The scale of the move in short interest is the standout this week. Estimated shares short have more than tripled since late August, rising from roughly 43,000 to 147,562 by October 6, a gain of 132% over the past month and 13% in the past week alone. For an ETN that historically attracted little borrow demand, that pace of accumulation is notable. Cost to borrow has moved in parallel, climbing to 1.24% from levels below 0.1% in mid-August, an increase of more than 1,350% over the month. The borrow market remains accessible rather than stressed: availability is running at 117.6% of short interest, and the 52-week low availability reading was 110%, so there is no sign of a squeeze-level tightness in the lending pool. The ORTEX short score has also climbed steadily, reaching 54.4 on October 6 after sitting near 30 in late September, reflecting the building pressure from multiple positioning signals at once.
Options traders are telling a different story, and the contrast is worth naming. Despite the surge in short interest, options positioning looks firmly bullish. The put/call ratio is 0.27, below its 20-day average of 0.36 and close to its 52-week low of 0.22. The z-score of -0.72 confirms that put demand is running below the recent norm, not above it. In other words, participants using derivatives are leaning into upside exposure, not hedging against a decline. That divergence between rising short stock positions and call-heavy options flow creates a genuinely unusual setup.
Price action sides with the bulls for now. FNGS is up 2.3% on the week and 4.2% over the past month, closing at $84.21 on October 6. The ETN tracks the NYSE FANG+ index with leverage, so its moves are amplified versions of the underlying mega-cap tech basket. With no earnings event on the calendar and no analyst coverage to speak of (this is a structured note, not a single stock), the near-term price driver is simply the direction of the underlying index names.
What to watch is whether the short interest build continues at its recent pace or stabilises, and whether the options call skew holds even as the borrow demand grows. A convergence of those two signals in the same direction would clarify which group of market participants is correctly reading the next move in FANG+ tech.
