TAN enters the second week of June in a sharp contradiction — short sellers are retreating fast, yet options traders are more cautious than they have been all year.
The price action tells the story first. The Invesco Solar ETF dropped 14.4% on the week to close at $61.83, erasing a month's worth of directionless trading in a matter of days. The single-day move on June 9 was a 2.75% decline. This is not a gentle drift lower — something spooked solar-exposed investors this week.
The options market is flashing the clearest warning signal. The put/call ratio climbed to 0.88 by Monday's close, nearly 2.75 standard deviations above its 20-day average of 0.80 — the highest defensive reading on record for TAN over the past year outside of an obvious tail event. That z-score is a standout. Demand for downside protection has picked up sharply over the past three sessions, with the PCR grinding from 0.79 at the start of June to 0.88 by June 9. Options traders are hedging, not speculating.
Short positioning tells a very different story — and the contrast is the most interesting thing about this note. Bears were actually exiting the trade into the sell-off. Short interest fell 31% over the week to roughly 965,000 shares, now equal to about 4.9% of the float. That's down from a high near 1.5 million shares at the start of June. Borrowing costs have eased alongside the retreat — cost to borrow dipped to 5.67%, its lowest level in six weeks, down from a recent peak above 7.3% in early May. Availability has loosened dramatically too: 15 shares are now available to borrow for every one already lent out, after spending most of May and early June at much tighter levels. The borrow market is not signalling a crowded short thesis — it signals shorts covering, possibly locking in gains after the week's drop.
The ORTEX short score has also eased notably. It printed at 36.6 on June 9, down from 51 just eight days earlier on June 1. A falling short score alongside falling short interest and loosening borrow availability paints a consistent picture: the bears who were most active in May have largely taken their money off the table. What remains in the fund at 4.9% short interest is a residual position, not a building conviction trade.
The broader setup for solar is worth contextualising. TAN is an ETF tracking global solar names — it carries no earnings date, no analyst consensus, and no independent valuation multiples. The week's 14% decline is almost certainly a response to macro or policy-related news flow hitting the sector, rather than fund-specific mechanics. Dividend data is stale, last recorded in early 2020. The fund's behaviour is entirely driven by the underlying solar equity basket and how investors are pricing the energy transition trade right now.
What to watch: whether the put/call ratio sustains its elevated reading into next week — a return toward the 0.80 mean would suggest the hedging rush was a one-week reaction, while a continued climb would point to a more sustained defensive rotation out of solar exposure.
