NEW YORK, Dec. 27, 2025, 7:54 p.m. ET — Market closed (weekend)
Applied Optoelectronics, Inc. (NASDAQ: AAOI) heads into the weekend after a sharp Friday selloff that reminded investors just how volatile “AI data center optics” plays can be—especially after a powerful multi-session run-up.
AAOI last closed at $37.17, down $3.83 (-9.34%) from the prior close, with Friday’s action spanning roughly $41.00 (open) down to the $37 area on elevated volatility. [1]
With U.S. stock markets closed until Monday’s opening bell, the key question for investors is whether Friday’s drop was a healthy reset after a momentum surge—or a warning that execution and guidance concerns are starting to re-price the story.
AAOI stock price action: Friday’s drop capped a whipsaw week
The magnitude of Friday’s move stands out even more when placed in context:
- AAOI had exploded higher earlier in the week, including a major jump on Dec. 22 (one of several outsized sessions in recent trading). [2]
- By Friday, that momentum reversed hard, with the stock finishing at $37.17 after trading as high as about $41 earlier in the session. [3]
This type of “rip higher, snap back” pattern is common in smaller-cap, high-beta hardware names when sentiment shifts from “AI demand at any price” to “prove it with shipments and margins.”
What’s driving the move: profit-taking meets lingering guidance and execution debates
No single company press release hit the wire in the last 48 hours that definitively explains Friday’s selloff. Instead, commentary and analysis from market observers centered on a familiar set of issues for AAOI bulls and bears:
- Revenue outlook sensitivity (especially around the company’s fourth-quarter trajectory)
- Timing and shipment dynamics in data center transceivers
- Cost and profitability path (AAOI has been growing rapidly but has also posted losses)
Trefis, in a weekend analysis, framed the slide as reflecting “renewed concerns” tied to the company’s Q4 revenue outlook, potential data center shipment delays, and operational cost pressure. [4]
Importantly, management itself has previously acknowledged that shipment timing can influence quarterly optics: in its third-quarter results materials, AOI’s leadership discussed quarter-end timing issues affecting data center revenue recognition. [5]
All notable AAOI news in the last 24–48 hours
Here’s what appeared across widely followed market outlets over the past two days:
1) Midday “losers” tape mention (Friday):
Benzinga flagged AAOI among notable decliners during Friday’s session, showing shares down around the high-single digits at the time of publication. [6]
2) MarketBeat’s Friday move write-up (Friday):
MarketBeat published a recap noting AAOI’s decline and summarized the broader Street stance as mixed (including a wide range of price targets). [7]
3) Fresh institutional-holdings coverage tied to a filing (Saturday):
MarketBeat also published a piece citing an SEC filing indicating Rice Hall James & Associates LLC reduced its AAOI position during Q3, including share counts and estimated position sizing. [8]
4) Post-drop weekend analysis (Saturday):
Trefis published its “how deep can it go?” style breakdown, focusing on the implications of a sharp down day for a stock that has been trading as a momentum name. [9]
5) Bullish “breakout” thesis piece (Friday):
A Seeking Alpha commentary by Yiannis Zourmpanos argued that AAOI’s earlier catalysts—particularly around 800G hyperscaler demand—have reduced “qualification risk” and could support continued ramp, while still emphasizing valuation and execution risk. [10]
Taken together, the last 48 hours of coverage reads less like a fundamental “new negative” and more like a market digestion phase after a rapid run.
The core AAOI story investors are still trading: 800G ramps, hyperscaler demand, and silicon photonics
While the market’s focus has shifted to near-term price action, AAOI’s fundamental bull case continues to revolve around high-speed optical transceivers and next-generation optical components that support AI-era data center buildouts.
Two company updates from earlier in December still anchor that narrative:
1) 800G volume order: “major hyperscale customer” and Q4 revenue implications
Applied Optoelectronics announced it received its first volume order for 800G data center transceivers from a “major hyperscale customer,” with CEO Dr. Thompson Lin saying the company was “pleased” to receive the order and emphasizing its automated production lines. [11]
Management also pointed to tangible near-term financial relevance: AOI said it remained on track to meet 800G shipment expectations by year-end and reiterated that this could contribute $4–$8 million to Q4 revenue. [12]
Meanwhile, CFO/CSO Stefan Murry highlighted accelerating 400G activity with that hyperscale customer, including nearly $22 million in orders year-to-date (as described in the release). [13]
2) Laser announcement: silicon photonics and co-packaged optics positioning
Later, AOI introduced a new 400mW narrow-linewidth pump laser aimed at silicon photonics and co-packaged optics (CPO) applications—two themes that investors increasingly associate with the next leg of data center networking. [14]
In that announcement, Fred Chang, Senior Vice President and North American General Manager, positioned the product as supporting the industry’s move to CPO at “800G and beyond,” with samples available to select customers and volume production expected later in 2026. [15]
Earnings and guidance backdrop: strong growth, but profitability still under scrutiny
From the company’s most recent quarterly results release (Q3 2025), AOI reported:
- GAAP revenue of $118.6 million (up sharply year over year)
- A GAAP net loss for the quarter
- A Q4 outlook calling for revenue of $125 million to $140 million and non-GAAP EPS still in loss territory (per the company’s guidance ranges) [16]
Management commentary also underscored that demand strength (notably in CATV) helped offset areas where data center revenue came in slightly below expectations due to shipment timing, and it discussed manufacturing capacity ambitions (including U.S. and Taiwan buildouts). [17]
That mix—rapid top-line growth but continued losses and execution dependencies—is a major reason AAOI can swing hard on sentiment shifts.
Analyst targets and forecasts: a wide range, with “Hold/Moderate Buy” style consensus
AAOI’s selloff comes amid a Street landscape that remains notably split:
- TipRanks shows an average 12-month price target of $38.25 (based on a limited number of analysts in its dataset) with targets spanning from $15 to $50, and a consensus described as Moderate Buy. [18]
- MarketBeat lists an average target of $35.60 with a similarly wide $15 to $50 range, reflecting disagreement about how much of the upside is already priced in. [19]
On the bearish side, B. Riley previously downgraded the stock to Sell and set a $15 price target, citing valuation concerns even while referencing an anticipated hyperscaler ramp (the firm specifically mentions Amazon in its note, while the company itself has not publicly named the hyperscaler in the 800G order release). [20]
Meanwhile, Rosenblatt has been cited as maintaining a Buy recommendation in recent coverage. [21]
The bottom line: “the Street” isn’t delivering a single clean signal—AAOI is trading like a prove-it story where execution, margins, and customer ramps will likely decide which target range matters.
A volatility accelerant to keep in mind: short interest
AAOI has also drawn attention from traders because of meaningful short positioning. MarketBeat’s short-interest snapshot (as of mid-December) put short interest at about 12.7 million shares, roughly 19.5% of the float (per its reported figures), which can amplify both rallies and pullbacks. [22]
High short interest doesn’t guarantee a “squeeze,” but it can contribute to fast moves when sentiment or news flow shifts.
What investors should know before Monday’s next session
Because markets are closed right now, Monday’s open (Dec. 29) is less about reacting to weekend price changes and more about whether new information emerges—and whether traders choose to “buy the dip” or reduce exposure into year-end.
Key items to watch before the bell:
- Any new company updates or filings
The most market-moving catalysts for AAOI typically come from customer/order commentary, product milestones, guidance updates, or material SEC filings. - Follow-through after Friday’s breakdown
Friday’s trading range (from roughly $41 down to the $37 area) creates an immediate roadmap for Monday: will buyers defend the prior low region, or does selling resume? [23] - Narrative tug-of-war: ramp confidence vs. profitability path
The bull case leans on hyperscaler-driven 800G/400G momentum and optical innovation (including silicon photonics/CPO components). The bear case leans on valuation, execution risk, and the still-unprofitable profile despite surging revenue. [24] - Year-end trading dynamics
Late-December sessions can see thinner liquidity, which sometimes magnifies swings in high-beta names—especially smaller-cap stocks tied to crowded themes.
Applied Optoelectronics stock enters Monday with a simple setup: a powerful AI-optics narrative, very real product and order milestones, and a market that just demanded a tougher standard of proof after a steep one-day decline.
