News & Analysis
Analyst notes, earnings, and industry developments across the portfolio
Cycle-peak anxiety emerging in memory
Micron posted record-shattering Q2 ($23.9B revenue, +196% YoY) but sold off 6% on $25B+ CapEx guidance. Samsung is entering Nvidia's HBM supply chain. SanDisk is up 155% YTD with analysts calling the breakout 'overdone.' This is the first clear 'good news is bad news' signal for the memory complex — the market is starting to discount cycle duration risk.
Photonics graduating from niche to S&P mainstream
Two photonics companies (COHR, LITE) joining the S&P 500 simultaneously is unprecedented. Tower Semi's 400Gbps/lane SiPho demo targets 3.2T transceivers. Citrini Research calls SiPh a 'secular growth at cyclical prices' opportunity with 50-70% penetration in 800G/1.6T modules. The thesis is strengthening on fundamentals — but TSEM +31%, AXTI +19%, IQE +143% in days means the easy money is made.
Nokia downgrade cluster signals timing risk for optical revenue
Three analysts (Danske, DNB, Arete) simultaneously downgraded Nokia despite strong OFC product launches. The concern: Multi-Rail shipping H2 2026 and coherent solutions mid-2027 means 12-18 months until revenue materialises. Morgan Stanley bucked the trend (PT €8.50). This is a classic 'product announcement vs. revenue reality' gap — applies broadly to pre-revenue positions like POET.
Insider selling at AXTI amid 19% single-day surge
CEO Morris Young divested 37,905 shares and Director Jesse Chen sold $1.35M worth of stock into the strength. Meanwhile gross margin is ~12% and profit margin is -27.68%. The stock is trading at $69 against a Wedbush PT of $28 and Northland PT of $35 — significantly above even the most bullish analyst targets. InP demand is real but the valuation is extreme.
SanDisk breakout looks overdone unless AI supercycle is real
SNDK up 155% YTD, now largest large-cap tech performer in S&P 500. Forward PE 18x looks modest but prior 1,200% surge raises sustainability questions.
Micron's earnings paradox: stock drops 6% despite blowout Q2
Q2 revenue $23.86B (+196% YoY), EPS $12.20 crushed consensus of $9.30, gross margins 74.9%. Market sold off on $25B+ CapEx guidance and Samsung entering Nvidia's HBM supply chain.
Bernstein: AI spending 'shows no signs of slowing' — valuations 'extremely attractive'
Stacy Rasgon published a bullish sector note lifting AVGO +4.7% and ASML +5.1%. Memory cycle expected robust through H1 2027.
Tower Semi + Coherent demo 400Gbps/lane in production-ready SiPho
Silicon MZM demo doubles lane speed for 3.2T transceivers (8×400Gbps). TSEM rallied 31.5% in the week. Tower consolidating as leading SiPho foundry.
COHR & LITE join S&P 500 — first photonics companies in the index
Mechanical index fund buying complete. Two photonics companies joining simultaneously signals sector mainstreaming. Watch for post-inclusion mean reversion over 2-4 weeks.
Nokia drops 4% despite OFC launches — triple analyst downgrade
Danske Bank, DNB Carnegie, Arete Research all downgraded to Hold/Neutral citing 'persistent macroeconomic headwinds.' Morgan Stanley bucked the trend with PT €8.50.
AXT surges 19.5% on analyst upgrades — but insiders are selling
Wedbush raised PT to $28, Northland to $35 on InP substrate demand. But CEO Morris Young and Director Jesse Chen both sold shares into the rally.
Corning surges 5.7% on OFC AI optical launches — BofA raises PT to $155
BofA's Wamsi Mohan raised PT to $155 (Buy) after Corning showcased multicore fibre, ultra-dense micro cable, and CPO systems at OFC.
IQE shares soar 143% in two weeks on takeover speculation
Under Takeover Code offer period since Sep 2025. Board negotiating non-binding offers with Lazard advising. FY2025 revenue weak (£90-100M) with negative EBITDA.
OFC 2026: 1.6T is commercial, 3.2T is the next target
Nearly 18,000 attendees. 224G lane speeds gaining momentum, 448G emerging. CPO and near-package optics draw significant attention for power efficiency.
Micron Q2 earnings: record revenue $23.86B, EPS $12.20 — stock drops
Revenue +196% YoY, gross margins 74.9%, Q3 guidance $33.5B. Sold off on $25B+ CapEx and Samsung HBM entry.
Meta signs $27B AI infrastructure deal with Nebius — transformative
Five-year deal ($12B dedicated + $15B optional) based on Vera Rubin platform. Nebius also has $19.4B Microsoft deal. Nvidia invested $2B directly.
NVIDIA GTC: $1T in Blackwell + Vera Rubin orders forecast through 2027
Jensen calls for TSMC to more than double capacity. Front-end wafer production is the bottleneck. Validates upstream equipment and materials thesis.
Citrini Research: 'secular growth at cyclical prices' in silicon photonics
Hyperscaler capex of $650-700B expected in 2026. SiPh penetration to reach 50-70% in 800G/1.6T modules. 'Enough yet-to-be-crowded names' in the sub-theme.
AAOI secures $200M+ first 1.6T volume order from hyperscale customer
First volume 1.6T order from likely Oracle. Shipments begin Q3 2026. Targeting 500K units/month of 800G+1.6T by year-end. Rosenblatt PT $140.
STMicroelectronics PIC100 enters high-volume production
SiPh platform now in volume production for 800G/1.6T transceivers. Best-in-class waveguide losses. Plans to quadruple production by 2027.
Aixtron surges 14.9% on AI chip tool demand — multiple upgrades
HSBC upgraded to Buy, Berenberg raised PT to €31, JP Morgan and Jefferies reiterated Buy. Renewed demand for deposition tools in AI chip and GaN production.
NVIDIA GTC + OFC 2026 — Strongest Week for the Thesis
March 12-19, 2026Two massive events hit simultaneously. NVIDIA GTC (March 16): Jensen Huang forecast $1 trillion in Blackwell + Vera Rubin orders through 2027, calling for TSMC to more than double capacity. Front-end wafer production is now the bottleneck. OFC 2026 (March 17-19): Every major optical company launched CPO products. The CPO transition has moved from 'coming eventually' to 'demonstrating now, shipping 2027.' This is the strongest week of evidence FOR the supply chain thesis since Citrini published.
Near-Term Catalysts
Risk Factors
Everything falls, but monopoly positions (ASML, SMHN) fall less than commodity suppliers. COHR/LITE/AAOI would be hit hardest as transceiver orders are first to be cut.
Upstream demand still exists (pluggables need the same materials) but the re-rating of equipment names stalls.
TSMC dependency remains even without owning the stock directly. NOK (Western InP fab) and STM (European SiPh) are partial offsets.
COHR, LITE, AAOI, and NOK are competing for the same hyperscaler orders. If pricing pressure emerges, all four positions (21.8% of portfolio) could underperform simultaneously.
POET's technology risk, SOITF's 70% premium to analyst target. This is why these are the smallest positions.
SOITF and SHECY trade on US OTC with wider spreads. IQE.L trades on AIM with micro-cap volatility. Use limit orders only.
If no takeover materialises, IQE could fall 50%+ to standalone fundamentals. This is why it's the minimum position size (2.3%).
What Has to Go RIGHT
- Hyperscaler AI capex stays at $600B+/year through 2027-28
- Photonics/CPO transition happens (whether on NVIDIA's H2 2026 timeline or delayed to 2028 — upstream demand is identical either way)
- Trough-earnings companies (STM, Soitec, Aixtron) actually inflect as photonics demand overtakes auto/mobile weakness
What Could Go WRONG
- AI capex gets cut 30%+ — but monopolies (ASML, SMHN) fall less than commodity suppliers; COHR/LITE/AAOI would be hit hardest
- Photonics transition delayed beyond 2028 — pluggables still need the same materials
- Taiwan contingency — TSMC dependency remains even without owning the stock; NOK and STM provide partial offset
- Individual blow-ups — POET technology risk, SOITF 70% premium. This is why they're the smallest positions

Citrini Research Alignment
Comparison with Citrini's “Let There Be Light” photonics basket (March 2026)
Citrini warns against COHR (“priced for perfection”), LITE (“the basket is a much better way to play it”), and AAOI (“no reason the stock couldn't trade 50% lower”). This portfolio deliberately diverges by including all three for direct transceiver exposure.
The 10 additional non-Citrini names (AVGO, ASML, MRVL, ANET, COHR, LITE, AAOI, MU, GLW, TSEM) bridge the mid-stream infrastructure and transceiver layers. TSM was removed due to broker constraints (unavailable on T212). Citrini's basket is pure photonics picks-and-shovels; this portfolio blends upstream monopolies with direct transceiver makers.
