longbridge-factor-screen
Fundamental multi-factor screener. Applies user-defined thresholds across PE, PB, ROE, revenue growth, profit growth, and dividend yield to filter a candidate list and rank survivors by composite score.
Response language: match the user's input language — Simplified Chinese / Traditional Chinese / English.
When to use
- "帮我筛选 PE < 15 且 ROE > 15% 的 A 股", "screen for low-PE high-ROE A-shares"
- "成长股筛选:营收增速 > 20%", "growth screen: revenue CAGR > 20%"
- "高股息蓝筹股 港股", "high-dividend HK blue chips"
- "价值选股:PB < 1 且 ROE > 10%", "value screen: PB < 1 and ROE > 10%"
- "多条件选股", "multi-factor stock screen"
For index/ETF constituent lists route to longbridge-constituent. For single-stock deep-dive route to longbridge-fundamental or longbridge-valuation.
Supported factors
| Factor | 简体 | 繁體 | Source CLI |
|---|---|---|---|
| PE (TTM) | 市盈率 | 市盈率 | calc-index or valuation |
| PB | 市净率 | 市淨率 | calc-index or valuation |
| PS | 市销率 | 市銷率 | calc-index or valuation |
| ROE | 净资产收益率 | 淨資產收益率 | operating or financial-report |
| Revenue YoY | 营收增速 | 營收增速 | operating or financial-report |
| Net profit YoY | 净利润增速 | 淨利潤增速 | operating or financial-report |
| Dividend yield | 股息率 | 股息率 | dividend or calc-index |
Workflow
- Collect screening criteria — ask the user if not given. Example defaults:
- Value screen: PE < 20, PB < 2, ROE > 12%, dividend yield > 2%
- Growth screen: revenue YoY > 20%, net profit YoY > 20%, PE < 40
- Obtain a candidate universe. Options (ask user):
- User provides a list of symbols.
- Use an index as universe (route to
longbridge-constituentfirst):longbridge constituent 000300.SH --format json # run --help for available flags
- Discover exact CLI flags before calling:
longbridge calc-index --help longbridge operating --help longbridge valuation --help longbridge dividend --help - Batch-query each candidate (call concurrently where possible):
longbridge calc-index <SYMBOL> --format json longbridge operating <SYMBOL> --format json longbridge dividend <SYMBOL> --format json - Filter in-context: discard symbols that fail any hard threshold.
- Score survivors: normalise each factor to 0–1 range within the passing set; compute weighted composite score. Default weights: ROE 25%, revenue YoY 20%, PE 20%, PB 15%, dividend yield 10%, net profit YoY 10%.
- Output the candidate table sorted by composite score descending (see Output section). Cite Longbridge Securities.
CLI
# Step 0: discover flags
longbridge calc-index --help
longbridge operating --help
longbridge valuation --help
longbridge dividend --help
# Step 1: get universe (if using an index)
# NOTE: JSON response uses key "stocks" (not "list") — extract symbols from data["stocks"]
longbridge constituent 000300.SH --format json # run --help for available flags
# Step 2: per-symbol data (repeat for each candidate)
longbridge calc-index 600519.SH --format json # PE, PB, PS, dividend yield
# NOTE: `operating` returns data for HK stocks only; for US/A-share use financial-report instead
longbridge operating 700.HK --format json # ROE, revenue/profit growth (HK only)
longbridge financial-report AAPL.US --format json # US/A-share fallback; run --help for flags
longbridge dividend 600519.SH --format json # dividend history
Output
Factor Screen Results — Source: Longbridge Securities
Criteria: PE < 20, ROE > 15%, Revenue YoY > 10%
Universe: CSI 300 (300 stocks checked) | Passed: N
Rank | Symbol | Name | PE | PB | ROE | Rev YoY | NP YoY | Div Yield | Score
-----|-------------|---------|------|-----|-------|---------|--------|-----------|------
1 | 600519.SH | Maotai | 28.1 | 9.5 | 31.2% | +18.4% | +15.7% | 2.1% | 0.87
2 | 601318.SH | Ping An | 8.2 | 1.2 | 14.8% | +12.1% | +10.3% | 4.5% | 0.79
...
Notes:
- Score = weighted composite (ROE 25%, Rev YoY 20%, PE 20%, PB 15%, Div 10%, NP YoY 10%)
- PE and PB: lower is better (inverted for scoring); ROE / growth / yield: higher is better
- N/A fields excluded from score denominator

Limitations
- Screening is applied to a user-supplied list or index constituents — this is not a real-time full-market screener.
- Data is point-in-time from the last available report; forward-looking factors require analyst consensus (
longbridge-fundamental). - If the candidate list exceeds ~30 symbols, process in batches and note that partial results are shown.

MCP fallback
When the CLI is unavailable, fall back to the MCP server. Discover available tools from the MCP server's tool list at runtime — do not rely on hardcoded tool names.
