Advantest (6857.T) — chart, structure and Closelooknet read

The Closelooknet read

Advantest makes the automated test equipment that every chip passes through before it ships: system-on-chip testers for processors and AI accelerators, memory testers for DRAM and high-bandwidth memory, test handlers that move devices through the testers, and system-level test cells that exercise a finished package as it will be used. Its customers are chip designers, foundries, memory makers and the assembly-and-test houses.

Company snapshot — Advantest

6857.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
Advantest makes the automated test equipment that every chip passes through before it ships: system-on-chip testers for processors and AI accelerators, memory testers for DRAM and high-bandwidth memory, test handlers that move devices through the testers, and system-level test cells that exercise a finished package as it will be used. Its customers are chip designers, foundries, memory makers and the assembly-and-test houses. It is based in Tokyo and, together with Teradyne, forms most of the world’s market for semiconductor test.
Where it sits in the stack
In Rubin, Advantest sits in Layer 3, Testing & Metrology — the stage that decides whether a die made at the foundry and stacked in the packaging plant actually works. Test time grows with chip complexity, so AI accelerators and high-bandwidth memory need more test per unit than the chips they replace; the test layer is where the build-out’s volume shows up as hours on a machine.
Who it is priced against
The name the market compares it with is Teradyne; inside its Rubin sleeve it sits with the metrology and inspection names — KLA, Onto Innovation, Camtek and Technoprobe.
Why Closelooknet tracks it
It is a Rubin constituent and one of the index’s Japanese names; the Morning 10 quotes it on the Tokyo open when the equipment layer moves.
What the diary watches
Whether test intensity per accelerator and per memory stack keeps rising as chips get larger, and whether the equipment names are sold together when the market questions the next round of tool orders.

Advantest (6857.T) trades on the TSE exchange in Japan, and sits in Layer 3 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.
