Coherent Corp. enters the back half of May with options traders at their most defensive in twelve months, even as the short-side story continues to quietly unwind.
The options signal is the sharpest data point this week. The put/call ratio has climbed to 1.15 — its highest reading of the past year, against a 52-week low of 0.52 — and runs about 1.6 standard deviations above its 20-day average of 1.07. That level of hedging demand is notable precisely because it has arrived alongside a stock pullback, not ahead of a known catalyst. COHR fell 2.5% on Tuesday and is down 5.4% on the week to $353.63, giving back a portion of the 21% monthly gain flagged in last week's note. The next earnings date is August 14, so options traders are not positioning around an imminent print — this looks more like a defensive response to a stock that has run hard year-to-date.
Short interest tells a quieter story. As noted last week, the post-earnings covering move has largely run its course. SI now sits at roughly 5.0% of the free float — essentially flat on the week, down just 1.4% — after dropping sharply from above 4.8% in late April. The borrow market has loosened considerably: availability has expanded to 3,822%, well into normal-to-loose territory, compared to the 52-week low of 680%. Cost to borrow dropped sharply to 0.20% as of Tuesday, down 41% on the week, its lowest level in the 30-day window. The ORTEX short score has continued to ease, now at 33.4 versus 35.4 a week ago. Taken together, the lending market is relaxed — there is no squeeze dynamic in play, and no meaningful fresh short-building to speak of.
The Street remains broadly constructive but the gap between price and targets has narrowed. Following a cluster of post-earnings upgrades in early May — TD Cowen lifted its target to $395, Rosenblatt to $425, and Stifel to $412, all maintaining Buy ratings — the consensus mean target now sits at $381, implying roughly 7.7% upside from the current price. That is a tighter margin than it was two weeks ago, when the stock was $60 lower than most targets. Morgan Stanley remains the outlier, holding an Equal-Weight with a $290 target, reflecting the bear case around stretched margins and uncertainty over AI demand timing. The valuation already prices in a lot: the trailing P/E is 54.7x, the EV/EBITDA 38.1x, and both multiples have contracted meaningfully over the past 30 days as the earnings beat has been digested. Factor scores offer a mixed backdrop — EPS momentum ranks well (73rd percentile over 30 days), but the 12-month forward EPS growth trajectory scores in just the 10th percentile, a reminder that near-term beats do not yet translate into a visible acceleration in forward estimates.
Insider activity adds a mild note of caution. CFO Sherri Luther sold 2,000 shares on May 12 at $372.96 ($746k), following a similar 2,000-share sale on April 22. Director Howard Xia sold a further 2,000 shares across multiple tranches on May 11. None of these transactions are large relative to the company's outstanding share count, and all carry low significance scores, but the direction — repeated small sales at rising prices — is consistent with executives trimming into strength rather than adding. The net 90-day insider figure shows a small net positive in shares, though the value figure is modest at roughly $7m and the buying appears to predate the recent rally.
Peer moves offer additional context on the week's weakness. Closest correlated peer FN fell 3.2% on the day, while GLW dropped 1.5% and is down 11.3% on the week. LASR has shed 17.1% over the same period. The broader photonics and electronic components complex is pulling back with COHR, suggesting macro or sector rotation pressure rather than a company-specific story.
What to watch: the gap between the options market's new defensive posture and the still-loose lending conditions — two signals that have historically pulled in the same direction — is worth monitoring as the stock tests whether the post-earnings enthusiasm holds at current levels.
