Co-Movement Graph Construct Data
A point-in-time news co-movement graph for A-shares, graded by a structural network — deep product peers, SAM supply chain, disclosed customer-supplier, and affiliates — to mark which co-movements are structurally grounded and which have no basis it can see. A risk/correlation overlay (information content, not a return signal). Daily refresh, S3 + signed-URL API.

The Data Itself
Live sample rows and every field's meaning, computed from the served data. The integrity strip arrives with this product's audit battery.
The dictionary is public below. Live sample rows need a sign-in — go to the Sandbox.
Every field, with its type and meaning.
| Field | Type | Description |
|---|---|---|
| trade_date* | date | as-of month-end (the PIT contract). |
| ts_a* | string · ts_code | first name of the pair (canonical order ts_a < ts_b). |
| ts_b* | string · ts_code | second name of the pair. |
| comention_strength* | int32 | SUBSTRATE: news co-mention weight over the trailing window. |
| comention_days* | int32 | SUBSTRATE: distinct days co-mentioned in the window. |
| trailing_corr* | double | SUBSTRATE: realized 90-day return co-movement (normalized measure). |
| lamp_product_peer* | bool | OVERLAY: the two firms share a product (any depth). |
| peer_depth* | int8 | OVERLAY: deepest shared SAM-tree level (>=4 = same specific product). |
| lamp_deep_peer* | bool | OVERLAY: peer_depth >= 4 — the standout forecasting lamp. |
| lamp_sam_chain* | bool | OVERLAY: SAM supply-chain link (core inputs). |
| lamp_disclosed* | bool | OVERLAY: disclosed customer-supplier, 2-yr active, bids excluded. |
| lamp_affiliate* | bool | OVERLAY: common ownership / cross-holding. |
| n_lamps* | int8 | OUTPUT: how many lamps are lit (the relatedness gate). |
| confirmed* | bool | OUTPUT: n_lamps >= 1 — structurally explained co-movement. |
| dark* | bool | OUTPUT: n_lamps == 0 — co-moving with no structural confirmation (THE DISCOUNT FLAG). |
| tier* | string | OUTPUT: grading tier.deep_peermultisingledark |
| expected_fwd_corr* | double | OUTPUT: forward-correlation forecast (develop-fit model). |
| corr_delta* | double | OUTPUT: expected_fwd_corr - trailing_corr — where the graph disagrees with the price screen. |
| cap_tier* | string | SCOPE: cap tier — pair is in a tier iff both names are members (the hedging edge is large-cap).CSI300CSI500CSI1000other |

Frequently Asked Questions

- Data for trade day T is published by 07:00 Asia/Shanghai on T+1, contingent on ChinaScope's upstream delivery. If upstream runs late, fallback delivery is T+1 18:00 SGT.
- What happens if ChinaScope is delayed?
- The API's manifest endpoint exposes a field (green/yellow/red). When red, calls for the current day return 404 with an header and ETA. Buyers can poll the manifest until status flips green.
