Notes

Nonpositive multiples are excluded rather than ranked as cheap. Inverse price-to-book from the val: namespace (tushare daily_basic pb, CN A-share only): low PB (cheap relative to book value) scores high, the daily-market-data counterpart of fund_book_to_market. Keyed by trade_date, so PIT-safe by construction with no filing lag. Missing dates or non-CN symbols stay NaN and are excluded from that date's cross-section. Lineage: JoinQuant style book_to_price_ratio; akshare/Eastmoney pb convention.
