Workflow

工作流程

  1. Identify universe: ask user for market (A-share / HK / US) and an index as screening pool (e.g. CSI 300, HSI, S&P 500).
  2. Fetch constituent list from the chosen index.
  3. For each constituent (up to 50 per batch), fetch valuation and financial KPIs concurrently.
  4. Apply value filters and score each stock.
  5. Present top candidates with supporting data.
  1. 确定筛选范围：询问用户目标市场（A股/港股/美股）以及作为筛选池的指数（例如沪深300、恒生指数、标普500）。
  2. 获取所选指数的成分股列表。
  3. 对每个成分股（每批次最多50只），同时获取估值和财务关键指标（KPI）。
  4. 应用价值筛选条件并为每只股票打分。
  5. 展示排名靠前的候选股票及相关支撑数据。

CLI

命令行工具（CLI）

Run 
longbridge <subcommand> --help
to verify exact flags before calling.
bash
undefined
调用前运行
longbridge <subcommand> --help
确认具体参数。
bash
undefined

Step 1: get constituent list (JSON key is "stocks", not "list")

步骤1：获取成分股列表（JSON键为"stocks"，而非"list"）

longbridge constituent <INDEX> --format json
longbridge constituent <INDEX> --format json

Examples: 000300.SH (CSI300), HSI.HK, SPX.US, IXIC.US

示例：000300.SH（沪深300）、HSI.HK（恒生指数）、SPX.US（标普500）、IXIC.US（纳斯达克指数）

Step 2: for each constituent symbol (run concurrently, batch of ≤20 at a time)

步骤2：针对每个成分股代码（并行运行，每次批次≤20只）

longbridge calc-index <SYMBOL> --format json # PE, PB, ROE, dividend yield, market cap longbridge valuation <SYMBOL> --format json # current snapshot + historical percentile longbridge dividend <SYMBOL> --format json # dividend history and yield
undefined
longbridge calc-index <SYMBOL> --format json # PE、PB、ROE、股息率、市值 longbridge valuation <SYMBOL> --format json # 当前快照+历史百分位 longbridge dividend <SYMBOL> --format json # 股息历史及股息率
undefined

Value Screening Criteria

价值筛选条件

Apply the following filters (user can adjust thresholds):
CriterionDefault thresholdRationale
PE (TTM)< 20 (A/HK); < 25 (US)Below market average
PB< 2.0Below book value or modest premium
ROE> 10%Profitability quality gate
Dividend yield> 2% (optional)Shareholder return signal
PE historical percentile< 50th pct (if available)Below own history
Gross margin> 20% (if available)Business quality filter
Composite value score = equal-weight rank across (PE rank asc, PB rank asc, ROE rank desc, dividend yield rank desc). Higher score = better value candidate.
Cyclical-industry caveat: for energy, steel, banks, shipping — low PE near a cycle peak may not signal undervaluation. Flag these and suggest using PB or dividend yield as primary metric.
应用以下筛选条件（用户可调整阈值）：
筛选条件默认阈值筛选依据
PE（TTM）< 20（A股/港股）；< 25（美股）低于市场平均水平
PB< 2.0低于账面价值或小幅溢价
ROE> 10%盈利能力质量门槛
股息率> 2%（可选）股东回报信号
PE历史百分位< 50%（若数据可用）低于自身历史水平
毛利率> 20%（若数据可用）业务质量筛选
综合价值得分 = （PE排名升序、PB排名升序、ROE排名降序、股息率排名降序）的等权重排名。得分越高，价值候选资质越好。
周期性行业注意事项：对于能源、钢铁、银行、航运行业——周期峰值附近的低PE可能并不代表被低估。需标记此类股票，并建议将PB或股息率作为主要衡量指标。
