Coherent Drops 11% on Results Day as Analysts Cut Targets

Coherent Corp. fell 11.3% on Friday to $210.32, giving back most of the 14% bounce that had looked so convincing just 24 hours before fiscal Q1 earnings landed.

The reaction resets the picture described in Thursday's note. Short interest had unwound sharply into the bounce, falling from above 11 million shares in mid-October to 9 million, or 5.7% of free float. That unwind looks like profit-taking into strength rather than a change in the underlying bear thesis. The borrow market is relaxed: cost to borrow sits at 0.37%, availability is at 3,025%, meaning roughly 30 shares are available for every one already borrowed. There is no squeeze pressure here. The ORTEX short score has edged down to 35.1 from 38.4 ten days ago, a mild easing rather than a clear directional signal. The more pointed question now is whether short sellers who covered will rebuild.

Options positioning is carrying more weight than the short interest figures right now. The put/call ratio closed Friday at 1.49, almost exactly in line with its 20-day average of 1.50, so the z-score is effectively flat. That sounds calm, but the absolute level tells a different story: 1.49 is close to the 52-week high of 1.72 and is structurally elevated. It peaked at 1.72 on October 19 before pulling back into results, suggesting some protective positioning was already in place. The ratio has not collapsed post-earnings, which means options traders have not declared the event resolved.

The Street moved decisively on Friday. Morgan Stanley cut its target from $375 to $325 while keeping an Equal-Weight rating, the clearest signal yet that a bellwether firm sees the post-earnings level as fair rather than cheap. B. Riley moved from $297 to $262, maintaining Neutral. Those cuts follow a week of downward revisions: Needham trimmed from $420 to $380, TD Cowen from $395 to $275, and Susquehanna from $425 to $350, all before results. The mean analyst target is now $394, nearly double the Friday close of $210. That gap is too large to ignore: it either reflects a street that has not yet fully revised down, or a market that has moved faster than the consensus can track. StoneX initiated with a Buy and a $425 target on October 26, a call that now looks immediately underwater. The analyst recommendation differential factor ranks at the 98th percentile, meaning consensus remains firmly bullish relative to most stocks in the universe, but the direction of travel is cuts, not upgrades.

The bull and bear cases both have live evidence behind them after this week. Bears point to $1.023B of negative free cash flow in FY26, inventory up 79.5% to $2.581B, and $11.8B of vendor commitments that limit financial flexibility. Bulls counter with the capacity expansion story: management has targeted a doubling of internal indium-phosphide capacity by September and another doubling by end of calendar 2027, and the $1.615B Data Center and Communications revenue line shows the demand is real. At a P/E of 18 and EV/EBITDA of 12.6, the valuation has compressed sharply from a month ago when the P/E was around 22. That compression is the market re-rating the execution risk, not abandoning the growth story.

Institutional flow coming into the earnings was not bearish. BlackRock added 1.66 million shares in Q3 to reach 8.4% of shares outstanding. T. Rowe Price added 1.54 million shares, ending the quarter at 1.56% of shares. Capital Research entered the register with a fresh 3.68 million share position. An activist remains on the schedule: BCPE Watson holds a Schedule 13D position, though the latest filing in February 2026 showed the stake had fallen from 5.2%, and the position may have been reduced further without triggering another filing. Stakes are as-last-disclosed and holders dropping below 5% can exit without further disclosure.

The prior two earnings events are instructive without being predictive. The August 2026 print produced a 7.3% gain on day one but a 11.5% loss over the following five days. The pattern of initial relief giving way to a five-day drift lower repeated in the prior quarter too. With Friday's 11.3% single-day move already in, the question for next week is whether the five-day drift dynamic plays out again, or whether the $210 level, now below the 30-day moving average and near a 28% loss on the month, attracts fresh institutional buying. The next concrete reference point is whether analyst targets continue to converge toward the current price, and how quickly the Street formalises revisions following the full results call.
