Company snapshot — Resonac

4004.T in five paragraphs: what it makes and sells, where it sits in the Closelooknet stack, who it is priced against, why we track it, what we watch. Research diary, not advice.

What it does
Resonac is a Japanese chemicals company formed from the merger of Showa Denko and Hitachi Chemical, making specialty chemicals and high-purity materials for electronics. Among its products are photoresists and other chemicals used in semiconductor manufacturing. It is based in Tokyo.
Where it sits in the stack
In Rubin, our index of the AI build-out supply chain, Resonac sits in Layer 5, Connectivity & Materials, within the Advanced Materials sleeve — specialty chemicals, photoresists and high-purity materials that foundries consume before a wafer can be processed. It acts as a supply constraint on the fabrication step: without these inputs chip production halts, even though the sleeve rarely draws attention.
Who it is priced against
Its Closelooknet peer group is the Advanced Materials sleeve of our Rubin index — Soitec, Entegris, Murata, Shin-Etsu Chemical, Siltronic and Sumco — chemical and materials suppliers to chipmakers, grouped for their shared position feeding the fabrication step. The market also names JSR as a comparable photoresist maker.
Why Closelooknet tracks it
It is a constituent of the Rubin Build-Out 100. Only one module of its Closelooknet score has been built so far, so the overall read is still in progress. It has appeared once in the Morning 10, in a note on Asian markets trading a broader AI demand pullback.
What the diary watches
The diary watches whether demand for advanced materials keeps pace with new fab and packaging capacity, given how far its price has recently pulled back from its 52-week high.

Resonac (4004.T) trades on the TSE exchange in Japan, and sits in Layer 5 of the build-out stack. Constituent of Rubin Build-Out 100.

  • Grid — 1×1 up to 2×2. Cells are synchronized: pan or zoom one and the others follow the same dates; the crosshair tracks across all of them. 4 INDICES loads Rubin · HALO · AEI · AW40 side by side.
  • Type / Scale — OHLC, line or area; linear or log price axis.

Picking a series

  • Tap the box in a cell's header to browse every Closelooknet series — headline indices, sub-indices, sectors, layers of all six families — plus the constituents.
  • Or type any ticker (NVDA, 7203.T, ASML.AS …) and press Enter — it charts in the cell straight from our data lake.

Studies

  • Overlays / Oscillators rows toggle the standard set (SMA, Bollinger, RSI, MACD …) per cell.
  • Levels (stock cells) draws the structure engine's support lines — regression bands, pivot cluster, SMA-200, the active fib zone.

Drawing

  • Tap a tool (Trend, Ray, H-Line, Fib, Channel, Rect, Note), then tap the chart once per point — the shape follows your finger or cursor between taps. The chart stops panning while a tool is armed; tap the tool again to release.
