ON Semiconductor's Options Signal Caution as Peers Rally

ON Semiconductor heads into its September 16 earnings print with options markets flashing the loudest caution signal in months — even as the rest of the chip sector moves higher without it.

The starkest data point on the day before the print is in options. The put/call ratio jumped to 0.674 on Monday — more than four standard deviations above its 20-day mean of 0.427. That is an extreme reading by any measure, and it arrived on the same session that ON fell nearly 6%, extending a month-long slide of 13% to $71.65. The defensive skew is particularly notable given that close peers rallied sharply on the day: NXPI gained 4.5%, TXN rose 3.8%, and ADI added 4.9%. ON moved in exactly the wrong direction while the group moved right. The divergence points to company-specific anxiety rather than sector-wide pressure heading into the release.

Short interest, by contrast, is not the story here. At 7.4% of free float — roughly 30 million shares — the short position is meaningful but not extreme, and it has drifted slightly lower over the past month. Borrowing costs are minimal at 0.38%, and borrow availability is extraordinarily loose at nearly 4,837% of shares short, well above even the 52-week floor of 724%. There is no squeeze setup, no crowding in the lending market — shorts are not the catalyst for the price weakness.

The analyst community is broadly still constructive but has been steadily trimming ambitions. Wells Fargo cut its target to $95 from $110 as recently as September 3, and following the Q2 print in early August, a wave of firms — Citi, Truist, Mizuho, and Wells Fargo again — all lowered targets while holding their ratings. The consensus sits at buy with a mean target of $106.88, implying roughly 49% upside from current levels. That gap has widened sharply as the stock has de-rated. Bulls point to ON's vertically integrated power semiconductor franchise, exposure to automotive electrification, and the strategic rationale of the Synaptics acquisition. Bears flag cyclical headwinds in the automotive market, long design-cycle risks, and heavy dependence on China — including EV relationships with Geely and NIO — amid ongoing regulatory uncertainty. The EV/EBITDA multiple has compressed about 2% over the past month, and the P/E has fallen more than 10% over the same period, reflecting the market's reduced patience for a recovery that has not yet appeared in the numbers.

The September 16 print will test whether ON can offer enough visibility on automotive demand recovery and margin trajectory to justify the Street's still-elevated targets — or whether the gap between $71 and $107 widens further.
