Aaoi Stock Falls 14% Ahead of May 7 Earnings
aaoi stock fell 14% in midday trading before its May 7 earnings report, with 756,465 shares changing hands in the opening 15 minutes as investors sold the optics group together. The move hit Applied Optoelectronics after a sharp run-up this year and left traders focused on whether the company can defend its AI-linked growth story tonight.
Coherent and Lumentum Slide
10% was the drop in Coherent shares during the same session, while Lumentum fell 7% and Ciena was lower by 10%, with Fabrinet down 8% in the same basket move. The selling showed up across names tied to AI data center demand, hyperscaler customer concentration, and overlapping product roadmaps in 400G, 800G, and 1.6T transceivers and co-packaged optics.
1 company that helped keep the group in focus was Coherent, whose fiscal Q3 2026 results came out after the close yesterday. Jim Anderson said the business saw “exceptionally strong demand across our datacenter and communications businesses,” and the company posted non-GAAP EPS of $1.41 versus $1.3943 consensus on revenue of $1.81 billion.
AAOI After 412% YTD
412% was AAOI’s gain year to date before today’s drop, a move that left the stock far ahead of the broader optics pack and made profit-taking easier to explain ahead of earnings. Lumentum had also risen 156% year to date, and Coherent was up 87% year to date, so today’s decline hit names that had already built in a lot of optimism.
75% of Coherent’s total revenue came from Datacenter and Communications, which rose 41% year over year to $1.36 billion. That mix kept the stock tied closely to the same trade that lifted AAOI, even as the market chose to de-risk before Applied Optoelectronics released its numbers.
May 7 Revenue Guide
$150 million to $165 million was Applied Optoelectronics’ revenue guide for Q1 2026, and that range is the figure traders will measure against when the company reports after the market close on May 7. If AAOI lands near or above that band, the 14% pre-earnings drop looks like positioning pressure; if it falls short, the selloff will read as a warning that the optics rally outran the underlying quarter.
30.55 points was the drop in Lumentum’s composite sentiment score over the past seven days, with chatter shifting from r/stocks to WallStreetBets and that forum reading at 18, a level described as very bearish. The shift adds a second pressure point for the group: even after the AI infrastructure narrative stayed intact, sentiment turned faster than the fundamentals did.
