The cross-sectional factors quant equity desks actually trade — computed from SEC EDGAR fundamentals joined to prices, not proxied by an ETF. Each factor is a winsorized cross-sectional z-score (higher = more attractive on that factor); the composite is their equal-weight blend. These are RANKS and context, not a backtested alpha: factors decay and crowd, free fundamentals are sparse for some tags, book/price is weak for intangible-heavy firms, and every value is lagged to the filing period (no look-ahead).量化股票交易台真正使用的横截面因子 — 由 SEC EDGAR 基本面与价格计算，而非用 ETF 代理。每个因子为去极值后的横截面 z 分数（越高 = 在该因子上越有吸引力）；综合为等权混合。这些是排名与背景，而非回测出的超额收益：因子会衰减与拥挤，免费基本面在部分科目上稀疏，市净率对无形资产密集的公司较弱，且所有数值滞后至申报期（无前视）。
Neural Web integration神经网络集成状态?Factor intelligence is context-only inside the Neural Web: it explains regime context and flags attention candidates for the cortex to consider, but it never ranks, scores, or originates signals (RUL-NW7). The BH-WITHHELD chip is mandatory until the 5-hypothesis family FDR sweep completes (per RUL-NW7, display-only interim).因子智能在神经网络中仅作为背景：解释市场体制背景，为皮层标记关注候选项，但从不排名、评分或发起信号（RUL-NW7）。BH-WITHHELD 标签为必须项，直至五假设家族 FDR 整体检验完成。

Does the rank actually predict? — point-in-time IC排名真的能预测吗？— 时点信息系数?The honest test most factor dashboards never show. At each quarter-end we rebuild every factor AS IT WAS KNOWABLE THEN — no look-ahead into a not-yet-filed 10-K (fundamentals are point-in-time) — then rank-correlate the factor score with the NEXT 63-day return: the Information Coefficient (IC). mean IC ≈ raw predictive edge; IC-IR (annualized) = IC ÷ its own volatility; t_HAC = Newey-West t-stat (overlapping forward windows autocorrelate the IC series); q_FDR = Benjamini-Hochberg false-discovery rate across every factor screened. One caveat the deep panel can't escape: prices cover only the currently-listed (delisted names are absent), so the deep read is survivorship-biased — an OPTIMISTIC bound. Judge each number against ZERO.大多数因子面板从不展示的诚实检验。在每个季末，我们按当时可知的信息重建每个因子（无前视、基本面为时点数据），再将因子分数与未来 63 日回报做秩相关，得到信息系数 IC。平均 IC ≈ 原始预测力；IC-IR（年化）= IC ÷ 自身波动；t_HAC = Newey-West t 值；q_FDR = 跨全部因子的多重检验错误发现率。深度面板的一个无法回避的代价：价格仅覆盖现存名（已退市名缺失），故深度读数含幸存者偏差 — 为乐观上界。每个数字都应与零比较。
Span 2011-03-31..2025-12-31 · 60 quarterly rebalances · ~1154 names — a DEEP 2011-2026 re-test on a backfilled close panel, not the ~3y rolling cache. The catch: that panel is SURVIVORSHIP-BIASED (delisted names absent — free prices only cover the currently-listed), so it is an OPTIMISTIC bound; a lone, marginal survivor is shown, not a green light. SUE — the strongest factor on the shallow 2023-2025 window — collapses to IC≈0 here. FINRA short-interest is dropped (no point-in-time history) and fundamentals refresh only ~annually, so fundamental factors still have few independent draws.区间 2011-03-31..2025-12-31 · 60 次季度再平衡 · 约 1154 只 — 这是 2011-2026 深度复检（回填的价格面板，而非约 3 年滚动缓存）。代价：该面板含幸存者偏差（已退市名缺失，免费价格仅覆盖现存名），为乐观上界；仅展示个别勉强通过者，而非买入信号。浅窗口（2023-2025）最强的 SUE 在此崩塌至 IC≈0。FINRA 做空数据因无时点历史而剔除，基本面约每年才更新，基本面因子独立样本仍少。
⚠ The equal-weight composite has NEGATIVE predictive IC.等权综合因子的预测 IC 为负。Its blended mean IC is -0.0072 over 60 quarters — the naive all-factor blend INVERTS the cross-section on this panel, so it is worse than useless as a stock screen. Do NOT trade the composite. Judge each factor on its own row below: only a factor tagged VALIDATED (survives BH-FDR AND positive mean IC) has earned it, and even that is a marginal survivor on a survivorship-biased panel.其混合平均 IC 为 -0.0072（60 个季度）— 朴素的全因子等权混合在此面板上反转了横截面，作为选股信号还不如不用。切勿交易该综合因子。请按下方每个因子各自的行判断：仅标记为 VALIDATED（通过 BH-FDR 且平均 IC 为正）的因子才成立，且即便如此也只是幸存者偏差面板上的勉强通过者。
Crowding / overlap拥挤／重叠?Factors that move together are redundant (a 'crowded' tilt). Mean absolute pairwise factor correlation, raw vs after Löwdin de-correlation; the composite (de-correlated) row above strips this overlap. VIF > 5 would flag a factor that is a linear combination of the others.彼此同向移动的因子是冗余的（拥挤的押注）。下为平均 |因子相关性|（原始 vs Löwdin 去相关后）；上方“综合（去相关）”行已剔除该重叠。VIF>5 表示某因子是其它因子的线性组合。:
mean |corr| 0.137 raw → 0.055 de-correlated.平均 |相关性| 0.137 原始 → 0.055 去相关后。low_vol ↔ low_beta · 0.74quality ↔ accruals · 0.71
Market breadth市场广度?Share of index members trading above their own 50-day AND 200-day moving averages, across the S&P 500 / 400 / 600 caps. This is MARKET-MEMBER participation (is the rally broad or narrow?), NOT factor-portfolio breadth. Above ~60% = broad; a small/large divergence flags where participation is rotating. Small & mid breadth history starts 2023-07 (the divergence is on that common window).指数成分中股价同时高于自身 50 日与 200 日均线的比例，覆盖标普 500／400／600。这是市场成分的参与度（涨势是广泛还是狭窄），并非因子组合广度。约 60% 以上=广泛；大小盘背离提示参与度在轮动。中小盘广度数据自 2023-07 起。

Deep color + |z|≥2 = an outsized rotation. The small number is the relative return; the big number is the z.每个市值加权 GICS 行业相对标普的回报（各时间跨度），按该走势相对其自身过去一年分布的异常程度（z）着色。颜色越深、|z|≥2 = 异常轮动。小字为相对回报，大字为 z。
Factor performance — point-in-time portfolios因子表现 — 时点组合?Each factor built into a daily PORTFOLIO at every month-end, as it was knowable then (no look-ahead): long-only = cap-weighted top quintile with a 5% single-name cap; long/short = equal-weight top-minus-bottom quintile (a paper factor premium, NOT a shortable book). Long-only carries with the market (compare SPY); the long/short isolates the premium. Free fundamentals are ANNUAL, so fundamental factor ranks refresh only ~once a year per name — most rebalance turnover is the price legs (low-vol/low-beta). History is ~3 years; every Sharpe ships with a block-bootstrap CI that mostly straddles zero, and NO factor clears FDR on the IC scorecard. Descriptive context, not validated or tradeable alpha.在每个月末，将每个因子构建为日度组合（无前视）：纯多头=市值加权顶部五分位（单股5%上限）；多空=等权顶部减底部五分位（纸面因子溢价，非可做空组合）。Free fundamentals are ANNUAL, so fundamental factor ranks refresh only ~once a year per name — most rebalance turnover is the price legs (low-vol/low-beta). History is ~3 years; every Sharpe ships with a block-bootstrap CI that mostly straddles zero, and NO factor clears FDR on the IC scorecard. Descriptive context, not validated or tradeable alpha.
Rebased over 2023-06-12→2026-07-15 (38 month-ends). Free fundamentals are ANNUAL, so fundamental ranks refresh only ~yearly — most turnover is the price legs (low-vol/low-beta).

Multi-factor composite多因子综合?The RANKING here uses only the factor legs that carry a POSITIVE measured information coefficient on the deep-history (leak-free) scorecard, IC-weighted with a sign constraint — negative-IC / FDR-failing legs (e.g. low-vol, investment) are EXCLUDED from the order because they rank names in an anti-predictive direction (the blind equal-weight composite's own scorecard grades it ic_ir -0.049). The per-leg leaderboards below still show every leg, badged with its IC/FDR verdict. Validate-before-weight: the order a trader sizes off cannot be moved by a leg the scorecard rejects.此处排序仅采用在深度历史（无泄漏）评分卡上信息系数为正的因子腿，按 IC 加权并施加符号约束——负 IC／未通过 FDR 的腿（如低波动、投资）被排除，因为它们会使排序反向。下方各腿榜单仍展示全部腿并标注其 IC/FDR 结论。· ranked by排序依据: Value · Quality · Profitability · Shareholder yield · excluded (negative IC)已排除（负IC）: Investment, Low volatility
Insider conviction内部人信念SEC Form-4 ·SEC Form-4 · 6mo to 2026-03?Net OPEN-MARKET insider buying minus selling per company from SEC Form-4 filings (purchases code P, sales code S; grants and option exercises excluded). The SEC ships these as a quarterly bulk dataset, so this is the most recent COMPLETED quarter — a slow conviction read, not real-time. Clustered open-market BUYING is the more informative side (insiders buy for one reason; they sell for many).来自 SEC Form-4 的每家公司净公开市场内部人买入减卖出（买入代码 P、卖出 S；排除授予与期权行权）。SEC 按季度发布，故为最近一个完整季度 — 慢速信念信号，非实时。
Value估值?Cheap on fundamentals — a blend of earnings yield, book/price, sales/price and cash-flow yield (the cross-section Fama-French/Dimensional trade). Volatile and regime-dependent; book/price is weak for intangible-heavy firms.基本面便宜 — 盈利收益率、市净率倒数、市销率倒数与现金流收益率的综合。top前 25

Earnings momentum (SUE)盈利动量 (SUE)?Earnings momentum (SUE = standardized unexpected earnings). Latest quarterly EPS vs the same quarter a year ago, standardized by its own history — the post-earnings-announcement-drift effect: beats keep drifting up. Built point-in-time from free SEC EDGAR quarterly EPS frames; in our leak-free IC scorecard it is the STRONGEST positive factor and the one that survives the FDR control (validated on the 2023-2025 price window, like the rest of the zoo). ⚠️ A deep 2011-2026 re-validation (survivorship-optimistic) collapsed this edge to ~zero (IC 0.0005, HAC t 0.06, L/S Sharpe 0.09) — it held only on that shallow window (PEAD post-publication decay), so treat SUE as descriptive, not a validated scored factor.盈利动量（SUE = 标准化超预期盈利）。最新季度 EPS 对比去年同季、以自身历史标准化 — 盈利公布后漂移效应。基于 SEC EDGAR 季度 EPS 逐期点时构建；在防泄漏 IC 评分中（浅窗口）为最强正向因子且通过 FDR。⚠️ 深度 2011-2026 复验显示该边际接近零（IC 0.0005，t 0.06），仅在浅窗口成立 — 视为展示性因子，非已验证计分因子。top前 25
