Broadcom's integrated optics, electronics and packaging could lower custom-chip system costs because separate suppliers defend their margins. At similar valuations, it is preferred to Nvidia and has more room to beat expectations. Google TPU v8 shipments are estimated at 4.0M in 2026 and 9.1M in 2027, assuming Broadcom supplies the remainder after MediaTek's allocation. Anthropic financing adds value only if chip profit exceeds likely support payments and capacity costs. x.com  x.com 

MACOM's product catalogue covers much of the optics area that could benefit from an AI-driven shift in network bottlenecks. Siliconcodesign expects coherent and coherent-lite optics to play a bigger role as AI usage shifts the bottleneck from scale-up bandwidth to data-center networks and internet traffic. This is quite bullish for MACOM longer term. x.com 

MACOM is priced for perfection after going all-in on the second half. A $100M+ drop in cash went into a big inventory build of finished goods for 800G and 1.6T shipments, so if hyperscaler demand from Meta or Google softens even 5%, it could be left holding expensive specialized chips, and Q3 EPS guidance of $1.31-1.37 is wound tight. The quarter did show real execution: 800G LPO adoption has begun, data center guidance rose to about 40% growth, and its analog moat looks wider than feared. x.com 

Google's growing TPU business needs HBM, adding demand for Micron, SK hynix and the memory basket. Google Cloud rose 103% to $30.7B, with backlog reportedly $561B; UBS models more than double TPU shipments in 2027. Micron should be up double digits on this, not down 5%. Samsung has LTAs with 10 major customers and is negotiating with 10 more, targeting 60-70% of capacity under contract. x.com  x.com 

Alphabet's businesses beyond search are why it will lead the real AI boom. Google Cloud, DeepMind and Waymo broaden its reach, and its $900 million SpaceX investment is now worth $85 billion. Fear emerging as the shares fall is an opportunity; a decline toward the buy zone is welcome, even as Q3 capex has taken a large hit out of free cash flow. x.com  x.com  x.com  x.com 

MACOM is a hold amid the AI sector sell-off: its investment in IQE de-risks operations a lot, but Coherent and Lumentum are better ways to play the 800G and 1.6T transition. x.com 

MACOM's analog chips sit inside every 800G and 1.6T optical module Nvidia's Rubin needs, so modules cannot ship without it. MACOM is the volume supplier of drivers, TIAs and lasers. Lumentum ships the 200G-per-lane lasers, but MACOM owns share in the driver and TIA beside them, so a Rubin Ultra ramp in H2 2026 scales its optical line without new design wins. At 26x EV/sales and 156x earnings it looks rich, but it alone ships optical, RF and defense analog in volume. x.com  x.com  x.com 

Amkor's expansion in advanced packaging supports a bullish growth outlook as that work becomes more important. Packaging accounts for 88% of sales and computing revenue rose 25%; capacity spending explains negative free cash flow. Q3 EPS was $0.76, implying roughly 12x annualized earnings, while Q4 EPS guidance is $0.65-$0.75. The compute opportunity is only starting, despite the decline in mobile. x.com  x.com  x.com  x.com 

Broadcom's diverse networking exposure makes it one of the best positioned in the theme. The market has overlooked it year to date. Optical DSPs, Tomahawk and Jericho underpin the view; Tomahawk 6/7 ramps in 2027, and Tomahawk Ultra and optical DSPs should accelerate growth. New XPU customers and extended hyperscaler deals add to earnings upside and an eventual re-rating. Risks remain, and weak semiconductor flows warrant caution about calling a bottom. x.com 

MACOM is a concentrated photonics pick for terrestrial high-speed optics plus emerging space optical links. Capital was moved into MACOM and Tower Semiconductor after a full exit from Lumentum, as part of rotating toward less obvious, higher-conviction AI bottlenecks while long-term conviction in the AI buildout stays unchanged. x.com
