CN Reversal SleeveA股反转组合beta · accruing gradesBeta · 成绩累积中

The validated A-share edge — deepest-quintile 3-month WITHIN-SECTOR reversal — shipped at its own product unit: a MONTHLY-rebalanced, EQUAL-WEIGHT, small-per-name BASKET with NO confirmation gate (every gate tested flips the edge negative). This is a PORTFOLIO, not stock tips. Sleeve-level stats only.已验证的A股优势——季度内“同板块最深回撤”反转(最深五分位)——以其自身产品单元交付:按月再平衡、等权、单只小仓位的组合,且无任何确认门槛(每一个门槛都会让优势转负)。这是一个组合,不是个股建议。仅展示组合层面统计。

Survivorship-honest re-derivation (W5-A)幸存者偏差修正后再推导(W5-A)

The re-derived number on the survivorship-clean(er) RAW plane (data/china_stocks_raw — RAW/unadjusted, 1990–2026, append-only). This replaces the unreproducible 0.58 Sharpe as the honest headline. The trimmed-plane backcast below is an upper bound; these numbers are the tighter, more honest estimate.在幸存者偏差更小的原始价格面板(data/china_stocks_raw — 原始未复权,1990–2026,追加写入)上再推导的数值。本结果取代了无法复现的0.58夏普,作为诚实的标题统计。下方的裁剪面板回测为上界;本区块数据是更严格、更诚实的估计。

2024+ caveat: the most recent 29-rebalance tail is negative (2024+注意:最近29次再平衡尾部为负(-0.772%/reb, t -1.60) — CONFIRM keys on the two time-halves per pre-registration; the forward ledger adjudicates whether this is noise or a regime change.) — CONFIRM依据的是前后两半段(依预登记),前瞻台账将裁定这是噪声还是机制变化。
UPPER BOUND on the available plane: both substrates are pure-survivor on the delisting axis (0 of 1,469 raw names end before the panel max). The reversal signal buys the deepest decliners — precisely the population most likely to contain eventual delistings. True out-of-sample number is at or below this one. Substrate repair (PIT membership store retaining delisted-name terminal returns) is an F9/W1 task; until then every reversal number stays labeled an upper bound.可用面板上的上界:两个底层数据库均在退市轴上为纯幸存者(1,469只原始标的中0只在面板最新日之前结束)。反转信号买入的是跌幅最深的标的——正是最可能包含最终退市标的的群体。真实样本外数值等于或低于此数。底层数据修复(保留退市标的最终回报的时点成分库)是F9/W1任务;在此之前,所有反转数字保持标注为上界。

Trimmed-plane reconstruction (upper bound) — NAV vs CSI300裁剪面板重建(上界)——净值 vs 沪深300

24 rebalances次再平衡 · 24m

Reconstruction of the trailing ~24 monthly rebalances on the trimmed china_search plane (upper-bound plane — survivorship- and adjustment-inflated vs the raw-plane re-derivation above). Clearly marked reconstruction, not a live record. See the honest re-derivation block above for the tighter number.在裁剪后的 china_search 面板(上界面板——相比上方原始面板再推导结果存在幸存者偏差与调整价膨胀)上重建近约24次月度再平衡。明确标注为重建,而非真实记录。更严格的数据见上方诚实再推导区块。

Every rebalance is registered to its own point-in-time parquet and graded CSI300-relative, fill-realistic (T+1, locked-limit excluded). This is what the sleeve is judged on — not the backcast.每次再平衡都登记到自有的时点parquet,并按沪深300相对、真实成交(T+1、排除一字板)评分。组合以此为准——而非回测。

Accruing — the sleeve grades once enough rebalances mature (conventions locked in from day 1).累积中——待足够再平衡成熟后开始评分(评分惯例自第一天锁定)。 n=0
