Coherent Corp. has spent this week unwinding the very move that defined the previous note — the stock has fallen 17% from its June 2 peak, snapping back below the analyst consensus it had briefly overshot.
The reversal is steep and swift. Coherent closed Tuesday at $355.94, down 11% on the day and 16.6% on the week. That single-session drop erases most of the 17.6% surge from June 2 that had propelled the stock through every analyst target on the board. The mean Street target is $380.61, set in mid-May. Coherent is now trading below it again — and the speed of the round-trip will unsettle bulls who had been arguing the consensus needed to chase higher. The valuation compression is visible in the multiples: the P/E has fallen roughly 15 points over the week to 53.8x, and EV/EBITDA dropped nearly five turns to 37.5x. Neither level is cheap, and the compression reflects a market reconsidering what the data-center cycle growth story is worth after such a sharp run.
The positioning data complicates the narrative in an interesting way. Short interest actually fell this week — down 7% to 5.1% of the free float — after the rebuilding phase documented in the prior notes. Bears appear to have taken profits into the price spike rather than pressing new shorts into the decline. The borrow market remains entirely loose: availability is running at over 3,000% of short interest, meaning supply for new positions is effectively unconstrained. Cost to borrow is 0.45%, modestly higher than last week but still near its floor for the year. Options positioning has also softened slightly — the put/call ratio at 1.09 is actually below its 20-day average of 1.15, a mild reading that suggests options traders are not rushing to add fresh downside protection into the pullback. The net read: the short side is less aggressive than the price action implies, and the borrow market offers no squeeze threat.
The Street had been uniformly bullish heading into this week's move. After May's earnings print, TD Cowen raised its target to $395, Rosenblatt to $425, and Stifel to $412 — all maintaining Buy ratings. Rothschild initiated at $455 in May as well, the most aggressive number on the board. Morgan Stanley is the outlier, holding Equal-Weight with a $290 target. The bull case centres on Coherent's CPO market expansion, rising indium phosphide capacity, and data-centre backlog strength. The bear case — China revenue concentration and aggressive production ramp risk creating pricing pressure in datacom transceivers — looks more relevant this week after the sharp reversal. Note that the analyst consensus is dated to mid-May; the stock has moved considerably since those targets were set, and none of the cited actions are recent enough to treat as a fresh read on today's price level.
Insider activity adds texture here. CEO Jim Anderson sold 25,836 shares on June 3 at $426.89 — near the exact session peak — for just over $11 million. That trade lands a day after the blow-off top and carries the look of well-timed distribution. The CFO also sold 2,000 shares in mid-May near $373. Net insider activity over 90 days is technically positive in share terms due to award grants, but the discretionary sales are directionally clear: senior management sold into the rally, not through it.
The peer group amplifies the picture. GLW fell 13% on the week and FN dropped 16%, suggesting the photonics and optical-component space is under broader pressure — this is not idiosyncratic Coherent weakness. LASR was the worst performer among close correlates, down 17%. Against that backdrop, Coherent's decline tracks the cohort rather than standing out, which may limit the narrative that company-specific factors are driving the move. The next earnings date is August 14 — until then, the debate will centre on whether this week's pullback represents a healthy reset within a structural data-centre upcycle or the beginning of a more sustained de-rating.
