FSLR is drifting lower with no catalyst to shake short sellers loose — down 1.4% on the week and 16% over the past month — while the October 27 earnings date draws closer and the covering impulse that defined mid-August has clearly run its course.
The most notable shift since the previous note is the stall in short-covering momentum. Two weeks ago, shorts were retreating at pace, with SI pulling back sharply to 9.1% of the free float. That compression has stopped. The borrow market offers no friction to new shorts: availability remains well-supplied and cost to borrow is near-negligible, meaning nothing in the lending structure is pushing bears to exit. When covering pressure fades and borrowing stays cheap, the path of least resistance for SI is sideways or higher — not lower.
Options positioning has been consistently defensive, and the latest price action has done nothing to change that. The put/call ratio was already running close to 1.8 standard deviations above its 20-day average by late August. With the stock printing fresh monthly lows into September, demand for downside protection has held firm. The factor scores add context: the short score ranks in just the 17th percentile, and the days-to-cover rank sits at the 12th percentile — both reflecting a market that is positioned cautiously on this name relative to peers. The analyst recommendation divergence score, at the 98th percentile, is the outlier: the Street remains broadly constructive on First Solar even as the tape tells a different story.
The institutional register shows some of that Street optimism has been acted on. Capital Research and Management added roughly 3.7 million shares in the most recent reported period, a meaningful accumulation that brings their stake to 3.83% of shares. BlackRock added around 208,000 shares over the same window, and State Street added roughly 291,000. The top of the register is being built, not trimmed. Whether those flows are enough to absorb whatever selling pressure accompanies the current slide is the open question — price action this week suggests they have not been sufficient.
The earnings history offers a useful reference point. First Solar's most recent print, on July 30, produced a 5.8% one-day gain and a 22.8% five-day rally — a sharp positive reaction that followed an earlier print in late July 2026 that initially fell 4.4% before recovering 17% over five days. The pattern is volatile rather than directional: the stock tends to move sharply on results, but the direction has been inconsistent. With EPS momentum scores in the 11th percentile on a 30-day basis and the 31st on 90 days, the growth narrative has softened materially since the start of the year, even as the EPS surprise score at the 75th percentile suggests the company has still been beating reduced expectations.
What to watch into October 27: whether short interest begins to rebuild from its 9.1% free-float base, whether the put/call ratio's elevated posture persists or normalises as the earnings date approaches, and whether Capital Research's large accumulation finds company among other long-side buyers willing to step in ahead of what has historically been a high-volatility reporting event.
