ON Semi Holds Up Better Than Its Peers as Analysts Trim Targets

ON Semiconductor slipped 1.4% over the past week, but that puts it well ahead of the crowd it runs with. The median decline across its closest peers was 3.9%. IFX fell 7.1%, MPWR dropped 5.4%, DIOD shed 5.9%, and ADI was off 4.3%. NXPI bucked the trend with a 5% gain, but ON's relative resilience was broadly notable in a week when analog and power semiconductor names faced wide selling pressure.

Short positioning tells a moderately bearish but not extreme story. Short interest in ON has crept up 1.2% over the past week to 7.6% of the free float, a level that has been drifting higher since late September. The month-on-month increase is 2.2%, so the rebuild is gradual rather than aggressive. Borrow conditions offer no squeeze pressure: availability is at 2,411%, meaning shares to borrow outnumber those already borrowed by a wide margin, even though that ratio has tightened sharply from above 6,000% in late September. Cost to borrow is 0.44%, up slightly on the week but still firmly in low territory. Options positioning is essentially neutral. The put/call ratio is 0.38, sitting just below its 20-day average with a z-score near zero, so neither side of the market is pressing hard through derivatives. Retail attention, measured by Wikipedia page views, ran at a z-score of 1.5 against the prior 90 days in early October, a notable uptick in interest around the time the stock was recovering from its September selloff.

The Street is split in direction, though the analyst-recommendation divergence factor ranks in the 99th percentile, suggesting meaningful disagreement about fair value. This week brought fresh cuts. Susquehanna's Christopher Rolland trimmed his target to $120 from $150 on Tuesday, keeping a Positive rating. TD Cowen cut to $75 from $95 earlier in the week, maintaining Hold. Those moves cap a run of target reductions: Truist, Stifel, and Mizuho all lowered targets in September, mostly to the $75 to $95 range, reflecting concern about the pace of margin recovery and automotive end-market weakness. Pushing the other way, StoneX initiated coverage this month at Buy with a $110 target, Wells Fargo raised to $100 from $85 at the start of October, and Needham reiterated Buy at $116. The consensus mean target sits at $102.81, a 36% premium to Tuesday's close of $75.62. The bull case rests on rising semiconductor content per vehicle, AI data-centre revenue targeted to scale from $500 million in 2026 to more than $2.5 billion by 2030, and a gross margin path from roughly 40% today to a 53% target by 2030. Bears point to a revenue decline from $8.25 billion to $6 billion between 2023 and 2025 alongside a gross margin collapse from 47% to 38%, arguing the business has severe downside operating leverage when fabs run light. Valuation sits at a trailing P/E of 17.6x and EV/EBITDA of 12.1x, both moving modestly higher over the past month as the stock recovered 8%.

The only notable insider transaction in the past 90 days was a planned sale: Group President Sudhir Gopalswamy sold 15,578 shares at $80.00 on October 1 for $1.25 million, executed under a pre-arranged 10b5-1 plan. Scheduled sales carry less signal than discretionary ones. On the institutional side, the 13D/G register shows no activist presence. FMR LLC filed an amendment on October 7 showing its stake had fallen to 8.2% from 15%, a material reduction over the filing period, though the exact timing of those sales is not disclosed. BlackRock's reported holding rose by 1.07 million shares to 10.5% of shares outstanding as of September 30, while Columbia Management added 4.16 million shares in the quarter to bring its stake to 1.4%.

ON reports Q3 results on November 2. The last two earnings prints produced day-one declines, with the September release falling 6.7% and the August report down 1%. The question heading into the November print is whether the gradual short rebuild and the analyst target cuts are pricing in another cautious revenue guide, or whether the combination of automotive content growth and early data-centre traction is enough to shift the narrative.
