Factor expression syntax & the 85-factor dictionary

1. There is only one expression shape

A factor expression is an `intersect([...])` call whose brackets hold a comma-separated list of conditions, meaning all must hold (AND logic):

intersect([factor1 op value, factor2 op value, ...])

# Example: PE between 0 and 20, ROE above 15%, dividend yield above 2%
intersect([PE_TTM > 0, PE_TTM < 20, ROETTM > 15, DividendRatioTTM > 2])

• Only `intersect` (AND) — there is no `union` / `or`
• No `between` / `in` / nested brackets — express ranges with two comparisons
• A factor may appear twice (as with `PE_TTM > 0` and `PE_TTM < 20`) — the standard way to exclude negative PE

2. Six comparison operators (that is all)

Simple expressions are allowed: measured support for `factorA > factorB * k`, e.g. the cash-collection template `GoodsSaleServiceRenderCash > OperatingRevenue * 0.9`.

3. Unit rules (the two that bite)

# OK: ROE > 15%, market cap < 5 bn CNY, dividend yield > 2%
intersect([ROETTM > 15, TotalMV < 5000000000, DividendRatioTTM > 2])

# WRONG: percentage written as a decimal (read as 0.15%)
intersect([ROETTM > 0.15])

• Percentages take plain numbers: `ROETTM > 15` means "ROE above 15%" (not `0.15`); `DividendRatioTTM > 2` means yield above 2%
• Money is in CNY: `TotalMV` is in CNY — 5 bn CNY is `5000000000`
• Ratios are plain multiples: `PE_TTM` / `PB` / `PS_TTM` / `CurrentRatio` take the number directly

5. Fourteen copy-paste templates

From the in-project factor dictionary measured record (verified 2026-08-31).

# 1) Low valuation + high profitability + dividend
intersect([PE_TTM > 0, PE_TTM < 20, ROETTM > 15, DividendRatioTTM > 2])
  --limit 20 --orderby ROETTM --desc

# 2) Graham-style (conservative)
intersect([PE_TTM > 0, PE_TTM < 15, PB < 1.5, DebtAssetsRatio < 50, CurrentRatio > 1.5])
  --limit 20 --orderby PE_TTM --asc

# 3) Growth (double-high)
intersect([PE_TTM > 0, PE_TTM < 25, NPParentCompanyYOY > 25,
           OperatingRevenueGrowRate > 20, ROETTM > 12])
  --limit 20 --orderby NPParentCompanyYOY

• Healthy cash flow: `intersect([PE_TTM > 0, NetOperateCashFlowTTM > 0, ROETTM > 10, DebtAssetsRatio < 60])`
• Low leverage: `intersect([PE_TTM > 0, DebtAssetsRatio < 30, InterestBearDebt < 1000000000, ROETTM > 10])`
• Small-cap value: `intersect([PE_TTM > 0, PE_TTM < 25, TotalMV < 5000000000, ROETTM > 10])` + `--orderby TotalMV --asc`
• Large-cap quality: `intersect([PE_TTM > 0, TotalMV > 100000000000, ROETTM > 12, DividendRatioTTM > 2])`
• Below-book recovery: `intersect([PB > 0, PB < 1, ROETTM > 5, NetOperateCashFlowTTM > 0])` + `--orderby PB --asc`
• High gross margin: `intersect([PE_TTM > 0, GrossIncomeRatioTTM > 50, ROETTM > 15])`
• Receivable risk scan (reverse use): `intersect([BillAccReceivable > 0, ARTDays > 180, ROETTM < 5])`

Combination principle: always include at least one "quality" factor (`ROETTM` or `NetOperateCashFlowTTM`), otherwise pure low-valuation screening tends to surface cheap-but-poor companies.
