New York, January 8, 2026, 13:44 (ET) — Regular session
- AAOI slid in afternoon trading, tracking a broader retreat in tech-linked names
- Optical networking peers also fell, pointing to a sector-wide move rather than a single headline
- Focus shifts to Friday’s U.S. payrolls report and AAOI’s next earnings update in late February
Applied Optoelectronics (AAOI.O) slid 14.9% to $32.40 in afternoon trading on Thursday after opening at $37.91, with about 6.2 million shares changing hands. The stock hit an intraday low of $31.70.
The drop landed as investors trimmed exposure to big tech, leaving the Nasdaq down about 0.5% around midday even as the Dow rose. “Investors might be repositioning their holdings,” Joe Saluzzi, partner and co-founder at Themis Trading, said, adding it was too soon to call it a lasting rotation away from tech.
Other optics and data-center networking names were also under pressure: Ciena (CIEN.N) fell about 14%, Lumentum (LITE.O) slid roughly 11% and Coherent (COHR.N) dropped nearly 9%. The iShares Semiconductor ETF (SOXX.O) was down about 1.7%.
Applied Optoelectronics is a vertically integrated maker of fiber‑optic networking products, selling into end markets that include internet data centers, cable television and telecom networks, Reuters data shows.
On the bullish side, Wall Street research has argued that AI data centers are pushing up demand for optical links — the fiber gear that carries data between servers and switches. Needham, writing on peer Lumentum, said optical spending intensity for AI infrastructure is rising and that the buildout is still in early innings.
But the trade can reverse fast. A pause in cloud data-center spending, or sharper pricing pressure among component makers, can ripple through smaller suppliers, and AAOI’s swings tend to widen when risk appetite fades.
