PLXS Holds Up Better Than Peers as Options Skew Stays Extreme

Plexus Corp. has had a rough week, but not as rough as the company it keeps.

Among its closest peers, the sector-wide selling has been severe. TTMI dropped 17.7% over the past five sessions. AEIS and JBL each fell more than 12%. KEYS was off nearly 10%. Against that backdrop, Plexus's 8.3% decline to $236.44 looks like relative outperformance, which is an odd thing to say about a stock that has lost more than $20 in a week. The median five-day move across its eight closest peers was around minus 10%, and several names were significantly worse.

The options market is the most striking data point in the snapshot right now, and it has barely moved from where it sat yesterday when the pre-earnings preview ran. The put/call ratio touched 0.085 on Tuesday, the lowest reading of the past 52 weeks, and it remains more than two standard deviations below its 20-day mean of 0.104. That call-side skew is extreme by any measure. It means options flow has been tilted heavily toward upside exposure for several days, even as the stock has weakened. The 52-week high for the ratio was 0.61, more than seven times the current reading, which gives some sense of how unusual the positioning looks relative to the stock's own history.

Short positioning tells a quieter story. Short interest sits at 3.4% of the free float, essentially unchanged from where Monday's note placed it. The week-on-week change is a small decline of around 2.5%. Borrow conditions remain loose: cost to borrow has fallen sharply, down about 29% on the week to 0.38%, and availability is effectively unconstrained, with shares available to lend running well above 80 times current short interest. There is no squeeze dynamic here. Shorts are not adding aggressively, and the market is not penalising them for being short.

The analyst community is uniformly constructive. All three analysts with active ratings carry buys, and the mean price target of $304.60 sits roughly 29% above the current price. The most recent rating change came from Keybanc in late September, an upgrade to Overweight with a $300 target. The bull case rests on record design-win pipelines in aerospace, defence and healthcare, management's stated expectation of more than $400 million in new programme growth this year, and FY27 and FY28 EPS estimates of $10.26 and $12.16 respectively. The bear case focuses on supply chain fragility, CFO transition uncertainty, and the risk that margin slips below the 6% operating target as ramp and compensation costs rise. The EPS momentum factor score of 94 suggests the earnings revision cycle has been strongly positive over the past month, and the analyst recommendation dispersion score also ranks in the 94th percentile, meaning the Street is more aligned on this name than on nearly any other in the universe. Valuation has de-rated modestly: the price-to-earnings multiple has contracted about 4.8 points over the past 30 days to 21.2 times, and EV/EBITDA has also moved lower to 13.2 times, which partly reflects the stock's pullback from August highs above $275.

Institutional flow offers one genuinely interesting detail. T. Rowe Price added 537,010 shares in the most recent reported period, a move large enough to lift its position to 699,257 shares and make it one of the more notable additions among the top fifteen holders. BlackRock increased its holding modestly to 4.36 million shares, keeping it comfortably the largest owner at around 16% of shares outstanding. No 13D activist has filed against Plexus, and all large-holder disclosures on the 13D/G register are passive 13G filings.

Plexus reports fiscal Q4 results after the close today. The stock's last earnings reaction, in late July, saw it fall just over 3% on the day before recovering strongly, up nearly 10% over the five sessions that followed. What to watch is whether the Q4 print and FY27 guidance are strong enough to close the roughly 30% gap between where the stock is trading and where analysts have set their targets, or whether the peer group's broad selling pressure proves more durable than the call-heavy options positioning currently implies.
