PLXS Call Skew Holds at Record Low as Earnings Arrive

Plexus Corp. reports this morning with the options market still at its most call-heavy extreme of the past year, even after a 9% slide over the past month.

The put/call ratio closed at 0.052 on Wednesday, barely above the 52-week low of 0.050 and more than 1.6 standard deviations below its 20-day average of 0.091. That reading was already extreme when the last preview ran on October 20. It has moved even further in the same direction since. Call volume has dominated for weeks, running through a period when the stock fell from above $260 to $239.34. The previous two previews flagged this skew as the standout data point; the data has not changed its message. Short interest, by contrast, has retreated: at 3.1% of the float and down 7% over the past week, it carries no weight on either side of the debate. Borrow availability is entirely loose and cost to borrow at 0.45% remains negligible.

The analyst consensus is unanimously bullish, with three buys and a mean price target of $304.60, roughly 27% above the current price. Keybanc upgraded to Overweight in late September with a $300 target, adding a voice to a chorus that includes Needham and Stifel. The bull case rests on demand broadening across healthcare, aerospace and defence, and an AI data-centre pipeline of around $500 million, alongside operating margins that exited FY25 above the company's own 6% target. Bears flag execution risk: a CFO transition, customer concentration, and the possibility that semicap demand normalises faster than the order book suggests. The stock's PE has contracted roughly 5.7 points over the past 30 days to 21.4x, meaning the multiple has already come in even as earnings momentum scores remain near the 94th percentile on a 30-day basis.

Retail attention has spiked sharply ahead of the print. The ORTEX alt-data attention signal, combining Wikipedia pageviews and ORTEX stock-page traffic, registered a z-score of 5.6 against the prior 90 days as of October 19. There are no measured leading datasets for Plexus that bear directly on today's revenue or margin figures, so this is colour rather than signal. On the institutional side, T. Rowe Price added 537,010 shares in the quarter to September, making it the most active buyer among major holders. CEO Todd Kelsey's October sales totalling around 1,500 shares were all under a pre-arranged 10b5-1 plan, which strips them of informational content.

The last two earnings reactions offer a wide range of outcomes. The October 2026 print saw the stock fall 6.6% the day after results and then recover to a 1.2% gain over five sessions. The July 2026 print triggered a 4.5% single-day gain that extended to 11.6% over the following week. Today's print tests whether the margin expansion story has continued on the trajectory that justified the stock's strong run through most of this year, and whether the AI data-centre pipeline has moved from pipeline to programme.
