Price and change in CNY (Hong Kong lines in HKD): each day's close converted back from USD at the ECB reference rate the figures were converted with. Market cap, volume and turnover are in USD.
ETF rows: “Market cap / AUM” is the fund's assets under management, and its turnover is dollar volume over those assets, which reads several times higher than a company's over its market cap. The two are different quantities, so sorting by either column orders companies and funds separately, companies first. Assets are today's figure, so for a range ending before the latest session a fund's assets and turnover show “—”.
