ANTIKYTHERA INDEX FAMILY · AUSTRALIA · LEVEL × CHANGE REGIME MAPS · DATA AS OF 13 AUG 2026

The Quadrant Playbook

For the headline index and each of the four pillars: the most probable direction of the AU 10-year yield, the ASX 200 and all eleven GICS sectors in every cell of the level × 3-month-change map — refined by the second derivative, anchored to the absolute level. Every measured figure is quoted from the Study II panel (Dec 2004 – Jul 2026, monthly, NW-adjusted); nothing here is recomputed.

Level +0.37 (70th pct), 3m +0.16 after −0.34 — the machine has swung back into the advance cell; historically +9.0% ann ASX, yields up ~10 bp/3m. The +0.16 3m Δ sits inside the ±0.25 noise band — row assignment provisional.

How to read the maps

Five maps — the headline index and four pillars. Axes: absolute level (x, split at neutral) × 3-month change (y). Each quadrant carries two sub-cells on the second derivative, ordered like the level axis: left d² < 0 (accelerating downward), right d² > 0 (accelerating upward) — rightward always means more upward force. The deeper into a quadrant the index sits, the more the level term dominates.

Direction glyphs: ▲ up / outperform · ▼ down / underperform · ◆ flat or no tested signal. Sector cells quote the measured mean 3-month return relative to the ASX 200 (percentage points) in that cell of the panel. The 10-year row quotes basis-point forward moves where the study measured them.

Colour rule: each asset's single BEST cell on a map is chipped verdigris, its single WORST cell bronze. The 10-year yield row is read as a holder of duration — green where the yield most probably FALLS, bronze where it most probably RISES.

Evidence tiers, marked per row: ● measured on the AU panel (|t| ≥ 2 on multiple horizons) · ◐ measured on the AU panel but weak, single-horizon, or read through the AU composite-bond proxy (bond returns inverted to yields) · ○ inferred from pillar mechanics — no tested cell. Inferred rows are judgement, and say so.

Confidence pips on the masthead cards score conviction out of five — more filled pips, more conviction, in the colour of the card's read.

Column guide — Index: the five machine lines, the headline composite plus its four pillars. Level: the latest index level in score points on the −2…+2 component scale (0 = neutral; the maps' horizontal axis). Pctile: where that level sits against the line's own history since Dec 2004 (100 = highest ever). 3m Δ: the three-month change in the level — the maps' vertical axis; positive = RISING row, negative = FALLING row. Prior 3m: the same three-month change measured one quarter earlier — the base for the second derivative. d²: the second derivative — 3m Δ minus prior 3m; positive means the move is gathering pace, and it selects the sub-cell within each quadrant. 12m Δ: the twelve-month change — the tail-warning input (trigger −1.25). Cell now: the quadrant and sub-cell the line occupies today. Current prints from context_au.json (13 Aug 2026).

The corrected risk-off flag (Study II)

Bearish is a fall that is losing pace — 3m change negative but shallower than a quarter earlier (early rollover: −2.84%/qtr ASX, n 29). An accelerating fall is contrarian-bullish (+1.72%/qtr, 64% hit): by then the damage is mostly priced. The sub-cells below carry the corrected definitions.
