longbridge-graham-screener

Prompt-only batch screener. Given a market or index universe, applies Graham's six hard filters (NCAV, PE, PB, dividend yield, debt coverage, earnings stability), scores each name on a 100-point static + dynamic composite, and returns a ranked cigar-butt candidate list with Graham buy lines, holding-period expectation, and value-trap warnings.

Response language: match the user's input language — Simplified Chinese / Traditional Chinese / English.

When to use

"港股里现在有没有 NCAV<1 的股票" / "港股裡現在有沒有 NCAV<1 的股票" / "any HK stocks with NCAV < 1"
"给我 A 股 PE 最低的 20 只股票，格雷厄姆标准" / "給我 A 股 PE 最低的 20 隻股票，格雷厄姆標準" / "top 20 lowest-PE A-shares by Graham standard"
"帮我筛一下符合格雷厄姆防御型投资者条件的美股" / "幫我篩一下符合格雷厄姆防禦型投資者條件的美股" / "screen US stocks meeting Graham defensive-investor rules"
"沪深300里的烟蒂股" / "滬深300裡的煙蒂股" / "cigar-butt names in CSI 300"
"每周更新港股 NCAV 排行榜" / "每週更新港股 NCAV 排行榜" / "weekly HK NCAV leaderboard"

For single-stock deep diagnostic use

longbridge-graham-stock-analysis

. For broader low-PE / low-PB / high-ROE value (not NCAV-centric) use

longbridge-value-screen

. For high-dividend-only screens use

longbridge-dividend-screen

Cognitive frame (do not skip)

Graham screening is patient arbitrage, not a dip-buy signal. Hold periods: 6–18 months (explicit catalyst), 1–3 years (sector re-rating), 3–5 years (organic accrual), or never (value trap — exit). Every ranking output must carry the waiting-cost (dividend yield) and the holding-period framing; never display a score number on its own.

Two failure modes the user must be able to distinguish — and the screener must signal:

"Cheap but time hasn't come" → NCAV stable QoQ, keep on the list.
"Value trap" → NCAV shrinking ≥3 quarters, persistent insider selling, negative OCF, PMI persistently <50, AR growth outpacing revenue. Override to ⚠️ regardless of static score.

Workflow

Confirm market + universe. Ask the user for: (a) market — HK / US / A-share, (b) screening pool — single index (HSI, S&P 500, CSI 300, NDX, etc.) or a watchlist. Default batch ceiling: 300 names per run.
Fetch constituent list for the chosen index (or watchlist) — see §CLI.
Sector pre-classification: exclude banks / insurance / REITs / pure financials / negative-equity / pure-holding shells from the universe before scoring — NCAV does not apply to balance sheets dominated by financial assets, so these are removed, not run through a substitute model. Count the exclusion in the Market Summary "Excluded — NCAV inapplicable" line. Separately, flag IPOs < 2 years (pro-rata earnings-stability sub-score, noted in row) and suspended names (last-trade snapshot, prepend ⏸).
Batch-fetch fundamentals in parallel (≤20 symbols per wave): balance sheet (annual + last 4Q), income statement (5y annual + 4Q quarterly), cash flow (4Q quarterly),

snapshot,

,

ownership
```
.
Apply hard filters with user-overridable thresholds — see §Filters.
Score each candidate — static (0–100) + dynamic adjustments + value-trap override. See
```
references/criteria.md
```
.
Reconciliation gate per row: if balance-sheet sum / current-assets sum / shares×price mismatches the reported total by >3%, drop the row from the leaderboard with a "data anomaly" note (do not silently average).
Rank by adjusted score (descending); default top 10–20 returned. Emit the table + market summary + waiting-cost note + suggested next step.
Append a Data Source Appendix (mandatory) listing every Longbridge endpoint hit, every WebSearch hit (publisher + URL + access date), fetch timestamps, and any field substitutions.
End every output with the recommendation: «本筛选器仅静态硬指标 + 通用动态因子，未考虑公司层面主观估值陷阱。命中候选请用

CLI

Run

longbridge <subcommand> --help

to verify exact flags before each call — the CLI is the source of truth, do not hard-code flag spellings from memory.

WebSearch fallback (use only when Longbridge has the gap)

Missing input	WebSearch query pattern
Industry PMI / inventory cycle	`"<industry> PMI <year>"` , `"中国制造业 PMI <month>"` , `"<industry> inventory cycle <year>"`
Capacity utilisation	`"<industry> capacity utilization <year>"`
Sector outlook (qualitative)	`"<sector> outlook <year> site:reuters.com OR site:bloomberg.com OR site:wsj.com"`
Recent insider transactions (if `ownership` is stale)	`"<ticker> insider selling <year>"` , `"<公司> 大股东减持 <month>"`

Each WebSearch-sourced figure must be tagged with publisher + URL + access date in the Data Source Appendix; never silently mix it into a Longbridge column.

Filters

User-overridable. Defaults from Graham's Intelligent Investor with light modernisation; threshold detail and the composite scoring weights live in

references/criteria.md

Filter	Graham threshold	Notes
NCAV ratio (market cap ÷ haircut NCAV)	< 1.0 ideal, < 1.5 acceptable	Core. Haircut: cash 100% / AR 75% / inventory 50% / other CA 25% / liabilities 100%
PE (TTM)	< 10 (defensive)	Rolling TTM
PB	< 1.5	—
Dividend yield (TTM)	> 3%	Waiting-cost compensation
Current assets ÷ total liabilities	> 2.0	Debt safety
Consecutive no-loss years	≥ 5	Earnings stability
Dynamic warning state	none triggered	Optional pre-filter; defaults to "show but flag"

Default rank key = adjusted cigar-butt score (static composite + dynamic adjustments + value-trap override). The user can override the rank key to: static-only, NCAV ratio asc, PE asc, dividend yield desc.

Special handling

Cohort	Treatment
Banks / insurance / REITs / pure financials / negative-equity / pure-holding shells	Excluded — NCAV is not a valid valuation lens for these business models. No substitute model is run; the symbols are dropped from the universe before scoring and counted in the Market Summary "Excluded — NCAV inapplicable" line. If the user wants these analysed, point them to `longbridge-valuation-methodology` or `longbridge-valuation` .
IPOs listed < 2 years	Earnings-stability sub-score pro-rated on available years. Mark row "数据局限".
Suspended stocks	Show last-trade snapshot, prepend "⏸ 停牌" / "⏸ Suspended" to the name, exclude from default top-N (still listable on request).
Reconciliation fail >3%	Drop from leaderboard; surface in a "数据异常待复核" footer list with the failing check named.
