A Chinese ETF’s disclosed share-count and net-asset history (period-end, not daily), from Eastmoney.

Tool description as the model sees it

Disclosed fund-share-count (基金份额) and net-asset history for a Chinese-listed ETF — period-end total shares outstanding (期末总份额), the period’s subscriptions/redemptions (期间申购/赎回), and period-end net assets (期末净资产), in shares and CNY. Answers ‘基金份额变动’, ‘ETF shares outstanding history’, ‘515050规模变动’, ‘how many shares outstanding does this ETF have over time’. IMPORTANT: this is NOT a daily series — Chinese ETFs publicly disclose 份额 only at quarter-end plus occasional ad-hoc material-change dates (confirmed live for 515050/561980/588170/588200), not every trading day; a from/to window with no disclosure inside it returns found:false naming the nearest disclosed dates rather than fabricating daily rows. For a daily PRICE series use ashares_daily_history; this tool is share-count/AUM only. Source: Eastmoney fund F10 archive (keyless).
