Company snapshot — Shin-Etsu Chemical

4063.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
Shin-Etsu Chemical is a Japanese chemicals manufacturer that produces silicon wafers used in semiconductor fabrication, alongside polyvinyl chloride and other specialty products. It supplies high-purity silicon wafers to chipmakers around the world. It is based in Tokyo.
Where it sits in the stack
In our index, Shin-Etsu sits in Layer 5, Connectivity & Materials, inside the Advanced Materials sleeve — the layer that feeds fabs the specialty chemicals and high-purity inputs a chip needs before any transistor is built. Shin-Etsu is a constraint on wafer supply into fabrication, since foundries cannot start a process without pure silicon stock.
Who it is priced against
Its peer group is the Rubin Build-Out 100's Advanced Materials sleeve, grouped for the same reason: specialty chemicals and high-purity inputs that rarely draw attention on their own. The names alongside it are Soitec, Entegris, Murata, Resonac, Siltronic and Sumco; the market also names Wacker Chemie as a comparable wafer and silicone producer.
Why Closelooknet tracks it
It holds a seat in the Rubin Build-Out 100. It carries a Closelooknet score, but only one module has been scored so far, so the read is still being built. The diary has quoted it once, in a dossier on the AI chip constraint chain, naming it a constraint on wafer supply.
What the diary watches
Whether fab expansion for advanced nodes lifts demand for high-purity wafers faster than new wafer capacity comes online.

Shin-Etsu Chemical (4063.T) trades on the TSE exchange in Japan, and sits in Layer 5 of the build-out stack. Constituent of Rubin Build-Out 100.

How to use this chart

Toolbar

  • Range — 1M to MAX on daily closes. 1D/5D switch a US stock cell to 5-minute intraday bars; index and foreign cells fall back to 1M daily with a note.
  • 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.
  • Drawings save per symbol in this browser and travel between the terminal and the asset page.
  • Delete key removes the selected drawing · Escape cancels a half-placed one · Clear wipes the symbol.

Wave counts

  • Wave places an Elliott count: tap the origin, then each wave end. Press Enter to stop early (inside wave 3 is fine) — dotted ghost targets sketch the remaining waves at guideline ratios.
  • On stocks the scanner's machine count appears automatically in grey — it is fully editable: drag any point, double-tap a label to remove it, Delete to dismiss it for good, Adopt to bring the machine's proposal back.
  • The sequence picker switches 1-5 / A-B-C / A-E / W-X-Y-Z; 1 2 3 cycles the degree; Subdiv starts a one-degree-smaller child count inside a wave.

Sharing

  • Card exports the cell as a branded PNG — chart, drawings and levels exactly as shown.
