Applied Optoelectronics (AAOI) had one of its worst single-session days of 2026 on Thursday, falling 17% after Meta CEO Mark Zuckerberg made comments that rattled the photonics sector.

Applied Optoelectronics, Inc., AAOI

AAOI opened at $120.95 on Friday, down sharply from levels above $140 earlier in the week.

Zuckerberg said Meta remained confident it would see clearer returns from AI investments within three to six months. But he also acknowledged that the company’s 2026 reorganization and layoffs hadn’t been “perfectly smooth.” That was enough to trigger a broad sell-off across AI infrastructure names.

Photonics peers Lumentum and Coherent Corp (COHR) also fell sharply on the day.

The sell-off stings, but context matters. AAOI is still up more than 205% year to date and over 320% over the past 12 months. Nvidia (NVDA), by comparison, is up around 3% in 2026. That’s a gap of more than 200 percentage points.

AAOI makes high-speed optical transceivers used to connect GPU clusters inside AI data centers. As hyperscalers ramped up AI infrastructure spending, AAOI became one of the market’s hottest momentum trades. That also means it carries high expectations — and little tolerance for doubt.

Institutional Buying Continues

Despite the volatility, institutional investors have been adding exposure. Ariose Capital Management disclosed a new position of 104,000 AAOI shares in Q1, valued at approximately $8.8 million. That makes AAOI its 6th-largest holding, representing about 5.9% of its portfolio.

Other firms including Allworth Financial, Northwestern Mutual Wealth Management, and Krilogy Financial also added or initiated positions recently. Overall, institutional investors own 61.70% of the company.

Insider Selling Tells a Different Story

While institutions buy, insiders have been heading for the exits. Over the last three months, insiders sold 500,215 shares worth around $86.7 million.

Director Cynthia Delaney sold 56,575 shares at $189.23 each in late May — a 48.68% reduction in her position. Insider Hung-Lun Chang sold 40,329 shares at $170.60 in June under a pre-arranged 10b5-1 plan.

Insiders now own just 3.80% of the company.

On the analyst front, Rosenblatt kept its Buy rating and $220 price target as recently as June 22. Raymond James reaffirmed an Outperform on June 10. Wall Street Zen is the outlier, downgrading to Sell back in April. The consensus sits at Hold with an average target of $113.80 — well below where the stock was trading before Thursday’s drop.

AAOI’s most recent earnings, reported May 7, showed Q1 revenue of $151.14 million — up 51.3% year over year but short of the $156.98 million analyst estimate. EPS came in at -$0.07, missing the -$0.05 consensus. The company set Q2 2026 EPS guidance in a range of -$0.03 to $0.03.

The 12-month trading range sits between $18.50 and $233.67, and the stock carries a beta of 3.69 — a number that tells you everything you need to know about how it moves.
