SolarEdge Heads Into Earnings With Borrow Tightening and Cuts Still Coming

SolarEdge Technologies enters its November 4 earnings window with a lending market that tightened sharply this week, analysts still cutting, and short sellers sitting on nearly a fifth of the float.

The most abrupt shift in the data this week was in the borrow market. Availability fell to 27% on October 20, from 83% just the day before. That is a dramatic single-session tightening. It brings availability close to its 52-week low of 20%, reached in mid-September. The cost to borrow rose 23% over the week to 0.81%, still a modest absolute rate but the direction is clear. Short interest edged up another 1.8% on the week to 19.4% of the free float, around 11.6 million shares. That is meaningfully lower than the 14 million shares short in mid-September, but the week-on-week rebuild, combined with availability tightening sharply, points to renewed demand for borrows ahead of the print. The ORTEX short score climbed to 70.9 on October 20, the highest reading in the past two weeks, ranking in the 4th percentile of the universe, meaning very few stocks carry a higher short score.

Options positioning runs in the opposite direction. The put/call ratio is at 0.42, below its 20-day average of 0.45, and the z-score of negative 1.2 means the market is leaning more bullish on options than usual. The 52-week range on the PCR is wide, from 0.28 to 0.92, so the current reading sits in the lower half, favouring calls. That divergence between a tightening borrow market and a call-heavy options book is the most interesting tension in the setup right now.

The Street has not changed its tone. BMO Capital cut its target from $31 to $28 on October 21, maintaining an Underperform rating, making it one of the more bearish near-term calls. JP Morgan lowered its target from $44 to $38 on October 19, keeping a Neutral. The mean analyst target now sits at $37.53, implying about 16% above the current price of $32.36, but the direction of revisions has been consistently downward since the post-Q2 target raises in September. The bull case centres on $3.3 billion of safe harbour commitments, improving Nexis economics, and 45X manufacturing credits. The bear case has more texture: US residential permits were down 31% year-on-year in Q2, market share fell to 22.3% from 25% in Q4 2025, and the path to sustained profitability remains policy-dependent. On valuation, the stock trades at 56x trailing earnings and 28x EV/EBITDA, multiples that have compressed somewhat over the past month. The EPS surprise factor score is 0, meaning the company has not beaten estimates recently, while 30-day EPS momentum ranks in the 88th percentile, a split that reflects recent estimate cuts rather than genuine delivery.

BlackRock added over 1.1 million shares in the quarter ending September 30, lifting its stake to 15.6% of shares outstanding, by far the largest institutional position. American Century added 937,000 shares in the same period. Harel Insurance added the equivalent of almost its entire prior position in one quarter, though its reported date is June 30 so the context for that move is now several months old. No 13D activist is on the register, and no Schedule 13D has been filed, so there is no activist angle here.

The last three earnings prints are worth noting. The Q3 2026 result in September produced a one-day move of negative 1.5%, which recovered to a five-day gain of 2.2%. The Q2 2026 print was a different matter: the stock fell 33% on the day and continued lower to a five-day loss of 34%. That was the single largest negative earnings reaction in the recent history. The upcoming November 4 release is therefore asymmetric in the minds of anyone who has been in the stock since summer.

With earnings two weeks away, the key question is whether the borrow tightening reflects genuine new short conviction or simply a technical dislocation in the lending pool, and whether options traders calling for upside are reading the setup differently from the shorts.
