SolarEdge shorts ease into earnings, but options signal fresh caution

SolarEdge Technologies enters its November 4 earnings release with one of the more conflicted setups in the solar space. Short sellers have been slowly retreating, the stock jumped 9% on the day, yet options traders just moved to their most defensive posture in months. The bulls and bears are not reading the same script.

Short interest, while still elevated, has been grinding lower. At 18.1% of free float, it has fallen roughly 4.6% over the past week and around 5% over the past month, the longest sustained retreat visible in the 30-day history. That unwinding has been orderly rather than forced. Borrowing costs have eased sharply too, down 30% over 30 days to just 0.57%, a level that signals no urgency among lenders. Availability is now back above 87%, close to the most loosely borrowed the stock has been in the past year. The 52-week minimum was 20%, so the current environment is nowhere near squeeze territory. Shorts are leaving, but they are walking, not running.

Options positioning tells a sharply different story. The put/call ratio jumped to 0.55 on November 3, more than three standard deviations above its 20-day average of 0.45. That is the most defensive options posture SEDG has seen in a very long time, the z-score of 3.09 putting it well outside the range of the past six months. The move is notable because it arrived just as the stock was rallying and short interest was retreating. Someone in the options market used that rally to buy downside protection, not to chase the move higher. The PCR sits in the middle of its 52-week range (high 0.92, low 0.28), so this is not a historic extreme, but the velocity of the shift is striking.

The Street is cautiously negative and has been getting more so ahead of the print. BMO Capital lowered its target to $28 from $31 on October 21, maintaining an Underperform. JP Morgan trimmed to $38 from $44 on October 19, keeping Neutral. Susquehanna and Barclays both cut targets in October while holding neutral-equivalent ratings. The consensus mean price target of $37.10 sits modestly above the current $32.88 close, implying about 13% upside on average, but most of the recent target moves have been in one direction. The bear case is concrete: US residential solar permits fell 31% year-over-year, US revenue dropped 20% quarter-on-quarter in the first quarter of 2026, and SEDG's US inverter market share slipped to 22.3% from 25.0% in the prior quarter. The bull case rests on the Nexis platform rollout, rising battery attachment rates, and management's $2.4 billion 2029 revenue framework with 35% gross margins and $1.7 billion of safe harbor inverter orders already in hand. Those are 2029 numbers; the bridge from here matters more in the near term.

ORTEX's short score, which aggregates borrowing signals, has been hovering in a tight band around 69 to 70 for the past two weeks, ranking in the fourth percentile of all stocks on a short-score basis. That means the stock is under heavier short scrutiny than 96% of the universe, even as the raw share count in short positions declines. The factor scorecard adds texture: EPS momentum over 30 days ranks in the 83rd percentile, one of the stronger readings across the scorecard, but the 90-day figure collapses to the 12th percentile, and the EPS surprise score is at zero. The EV/EBITDA multiple has ticked up to 27.7x, gaining roughly 1.2 points over 30 days even as the P/E pulled back to 53.4x. The price-to-book at 4.4x has also eased marginally. None of these multiples point to deep value at current levels.

BlackRock disclosed a 15.2% stake in its latest 13G/A filing from July 2026, and its institutional filing through September shows a further top-up to 9.58 million shares, an addition of over 1.1 million shares in the last reported period. That is the largest holder by some distance and suggests at least one large passive and active holder is not trimming. American Century added 937,000 shares in the same period, bringing its stake to around 1.7 million shares. On the other side, Harel Insurance's last disclosed position showed it holding 2.36 million shares after a large increase, but that data dates to June 30, so the picture may have shifted. All 13D/G stakes are as last disclosed around the 5% threshold, and holders dropping below that level may not file again.

The setup heading into the next reporting period (Q1 2027 is flagged for February 17, 2027) is a stock where the short base is retreating but not gone, options buyers are defensive despite the rally, and analyst targets are drifting lower even from mostly neutral ratings. What the February print needs to show, above all else, is whether the Nexis ramp and battery attach rates are moving the needle on margins, or whether the demand drag from residential market weakness is deeper than the 2029 framework assumes.
