Marble Circuit Insights
reading the chip cycle from the ground up

Free editorial articles on how artificial intelligence is changing investment research into semiconductor sector fundamentals — capacity, utilization, capex and the demand signals that move foundries in Hsinchu and beyond. Nothing is sold here. Inquiries welcome.

The view from Hsinchu

Why semiconductor fundamentals reward patient reading

Most commentary on AI in investment treats chips as a backdrop. We treat them as the question. Foundry utilization, lead times and equipment orders are leading indicators that earnings releases only confirm later — and they are readable long before the analysts in distant time zones catch up.

From die to decision

A finished die is a fingerprint of the cycle: node, yield, design rule and package all leave traces that an investor can learn to read. Our articles trace that path without offering personalised advice.

Focus areas

Three lenses on the semiconductor cycle

Each focus area is an editorial thread, not a paid tier. Read what interests you; write to us when you want a pointer to primary sources.

01 · Capacity

Foundry utilization & capacity ramps

How wafer-starts, fab loading and node-mix shifts at Taiwanese foundries translate into revenue guidance — and why a single percentage point of utilization matters more than a headline beat.

02 · Demand

AI-accelerator demand signals

Tracking HBM bandwidth, CoWoS packaging allocation and accelerator shipments as proxies for the build-out behind generative AI — and where the signal gets noisy.

03 · Capex

Capex cycles & equipment orders

Reading tool-maker bookings and fab capex guides as a forward look at supply, with attention to the long lead times that make semiconductor investment a multi-year wager.

Editorial method

How we read the sector, and who the reading is for

Our articles are written for readers who want to reason about semiconductor fundamentals themselves — analysts, operators and curious investors in Taipei and farther afield.

What we read

Primary sources first, commentary second

We start from foundry disclosure decks, equipment-maker bookings tables, industry association shipment data and on-the-ground capacity checks reported in trade press. Synthesis comes after the source, and every claim links back to a document a reader can open themselves.

How we evaluate

Slow signals over fast ones

Utilization and lead times move quarters before earnings. We weight them accordingly and avoid dressing up short-term price moves as analysis.

Who it is for

Readers who want to decide

For people who form their own view and want a second read of the fundamentals — not for anyone seeking a trade call or personalised investment advice.

The build-out behind the headlines

Every accelerator shipped is a commitment of power, packaging and capital. Our articles follow that commitment downstream — and invite your questions back upstream.
