协同波动图谱构建数据
覆盖中国 A 股的时点(PIT)新闻协同波动图谱,由结构化关系网络(深度产品同业、SAM 供应链、披露的客户—供应商、关联方)评级,辨别哪些协同波动结构上真实、哪些缺乏可见依据。风险/相关性数据层(提供信息含量,而非收益信号)。每日更新,S3 + 签名 URL API 交付。

数据本身
实时样本行与每个字段的含义,由所服务的数据计算得出。完整性记录即将随本产品的审计组件上线。
数据字典公开如下。实时样本行需要登录 — 前往 Matrix.
每个字段及其类型与含义.
| 字段 | 类型 | 描述 |
|---|---|---|
| trade_date* | date | as-of trade date — the PIT contract (validated history at month-ends; daily at the live frontier). |
| ts_a* | string · ts_code | first name of the pair (canonical order ts_a < ts_b; never self-paired, 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 |
