Morning movers: AAOI slides 12.2% on a $600M stock-sale plan

The August 24 Morning Read covers the wider market backdrop. These delayed pre-market quotes were requested between 05:47 and 05:50 ET on August 24, 2026 and checked against independent Nasdaq and TradingView snapshots; thin early trading can change quickly.

AAOI: -12.23% as a $600 million stock-sale program lands

Applied Optoelectronics entered an equity distribution agreement on August 21 that allows it to sell up to $600 million of common stock over time. The filing describes an at-the-market program, not a completed $600 million sale: AAOI has no obligation to issue shares and can suspend sales. That distinction matters, but the potential dilution is large enough to reset the price after Friday’s close.

• Why it matters: new shares can spread future earnings across a larger share count, even if the cash finances growth.
• Objective range: the early Nasdaq tape ran from $107.30 to $110.78, leaving the $124.82 prior close as the main overhead reference.
• Peer check: AXTI and COHR were also lower, but neither had the same new dilution filing.
• Main risk to the bearish reaction: AAOI may sell fewer shares than the authorization permits, or deploy proceeds into high-return capacity.

MRVL and MU: one sector event, two different exposures

Marvell and Micron moved lower together before a dated sector event. NVIDIA plans to post fiscal Q2 results at about 4:20 p.m. ET on Wednesday, August 26, followed by a 5:00 p.m. ET conference call. The synchronized pullback is consistent with investors trimming AI-hardware risk; it is not proof of a new company-specific problem at either Marvell or Micron.

• Why MRVL matters: custom AI silicon and high-speed connectivity make it sensitive to data-centre spending signals.
• Why MU matters: memory pricing and high-bandwidth-memory demand put it closer to the capacity and supply side of the AI build-out.
• What separates them: a common sector catalyst can move both stocks, but their revenue drivers, valuation and option surfaces are not interchangeable.
• Main risk: positioning can reverse quickly if NVIDIA’s demand commentary differs from the assumptions embedded in Monday’s pullback.

Also on the radar

• AXTI -5.09% at $67.14 near 05:43 ET: optical-material shares joined the pullback, but no separate current issuer catalyst cleared the feature bar.
• COHR -5.00% at $275.05 near 05:43 ET: the photonics supplier moved with the optical/AI complex rather than a distinct Monday filing.
• SNDK -4.62% at $1,522.30 near 05:43 ET: storage shares cooled after a powerful run; the move stayed radar-only without a new company announcement.

What to watch today

• 09:30 ET — opening auction: compare regular-session volume with the delayed pre-market prints and AAOI’s $107.30-$110.78 early range.
• After 09:35 ET — option chains: rebuild live spreads and strike-level open interest; the aggregate Cboe totals are not executable quotes.
• Through Monday’s close: watch whether AAOI remains a dilution-specific story while MRVL, MU, AXTI, COHR and SNDK trade as one risk cluster.
• Wednesday, 16:20 ET and 17:00 ET: NVIDIA’s written results and conference call become the next dated test for the AI-hardware group.
