Workflow

Step 1: Pull financials

get_financials(ticker, "income", "annual")   → last 5 years
get_financials(ticker, "balance", "annual")
get_financials(ticker, "cashflow", "annual")

Step 2: Get market data

get_quote(ticker)  → price, market cap, PE, PB
get_index_data("000001") → benchmark return for beta estimation

Step 3: Build projections

• Project revenue using historical growth rates adjusted for China macro outlook
• Assume 65-75% operating margin for 白酒 / high-margin sectors
• Assume 15-25% operating margin for manufacturing
• CapEx as % of revenue: check historical from cashflow statement

Step 4: Compute WACC

WACC = E/(D+E) * Ke + D/(D+E) * Kd * (1 - tax_rate)

Ke = Rf + β * ERP
  Rf   = China 10Y CGB yield (use ak.bond_zh_us_rate() or web search for latest)
  β    = regression on 上证指数 returns (or use comparable firm beta)
  ERP  = 6-8% (China-specific equity risk premium)

Kd   = China 5Y corporate bond yield + credit spread

Step 5: Terminal value

Terminal Value = FCF_(n+1) / (WACC - g)
g = 3-4% for mature Chinese companies (China nominal GDP growth)

Notes

• Chinese fiscal year ends December 31 for most companies
• 北向资金 (Northbound flow) data can be used as sentiment indicator
• 商誉 (goodwill) impairments are common in China M&A — flag if goodwill > 30% of equity
• Some Chinese financial statements are reported in 千元 (thousands of CNY) vs 元 — check the unit
