本页由任务链自动生成(15m cadence / 双页结构),用于保证 P2/P3 rank 在 factors 目录有独立报告入口。生成时间:2026-04-08 11:33:27 北京时间
stage:P3 | status:bench
策略类型(mother theme):均值回复
角色(role):challenger
挑战基线(challenge baseline):均值回复主baseline(pairs/fair-value)
唯一增量(unique increment):cbETH-ETH rolling fair-basis MR
下一步唯一动作(next action):先解除交易接入阻塞(Coinbase),否则维持 shelve
核心思想:价格偏离某个“相对公平值”后,倾向于回归;常见风险是趋势单边把回归交易持续压制。
当前 rank 要回答的核心问题:这条“独立增量”到底是在补 baseline 的哪个短板(入场、过滤、仓位、退出、执行)?
| 层 | 内容 | 说明 |
|---|---|---|
baseline | 均值回复主baseline(pairs/fair-value) | 研究母体(被挑战或被增强对象) |
rank increment | cbETH-ETH rolling fair-basis MR | 该 rank 相比 baseline 的独立增量 |
role: challenger | 挑战/替代 baseline 的候选路线,先追求可解释增量,再看成本后存活。 | 该 rank 在 P2/P3 体系中的职责边界 |
current next_action | 先解除交易接入阻塞(Coinbase),否则维持 shelve | 当前运营决策建议(用于 P2→P3 或回退) |
均值回复主baseline(pairs/fair-value)(若该 rank 不是 baseline,本项为“被挑战或被增强的母体”)。cbETH-ETH rolling fair-basis MR,要求在报告中单独说明它改变了 entry / filter / sizing / exit 的哪一段。均值回复,建议按“信号本体 vs 过滤层 vs 执行层”三段写清。challenger,需要明确它是否应独立承担 alpha 归因。reports/artifacts/paper_rank183_cbeth_eth_basisreports/artifacts/rank183_pair_proxy_scan_20260401| artifacts 目录 | 总文件 | md | csv | json | html | log/txt |

# Rank 183 deep-dive proxy scan (2026-04-01) ## Goal Answer three concrete user questions: 1. Why does Rank 183 use `CBETH spot + ETH perp` instead of two generic coins on the same exchange? 2. How stable is Rank 183 historically, month by month? 3. If we switch to generic crypto pairs like `BTC/ETH`, `ETH/SOL`, `ETH/XRP`, `SOL/XRP`, can simple correlation be turned into a tradable mean-reversion strategy? ## Key conclusion - `Rank 183` is a **basis mean-reversion** strategy, not a generic cross-asset pair trade. - The reason it uses `CBETH spot + ETH perp` is that there is a clearer economic anchor: - `CBETH` is a staked-ETH spot asset with a premium/discount structure, - `ETH perp` is the cheap hedge leg for broad ETH beta, - so the trade is betting on **basis / fair-value convergence**, not just "these two charts usually move together". - By contrast, `BTC/ETH`, `ETH/SOL`, `ETH/XRP`, `SOL/XRP` are mostly **cross-asset correlation pairs**. They may co-move, but they do not automatically have a stable fair-value anchor strong enough for post-cost mean reversion. ## Rank 183 local honest sample Using the current artifact: - `reports/artifacts/quant_digests/cbeth_eth_basis_probe_20260326_0850_15m/trade_log.csv` The local trade log only spans: - start: `2026-02-01 18:45 UTC` - end: `2026-03-26 08:45 UTC` So the exact current paper-spec evidence is only about **2 months**, not 1 year / 3 years / 5 years. Also, an exact `5y` backtest on the same instrument is not literally possible because `CBETH` itself is younger than 5 years. ### Monthly split in the local trade
