簡要介紹
黃金ETF基金是指一種以黃金為基礎資產，追蹤現貨黃金價格波動的金融衍生產品。由大型黃金生產商向基金公司寄售實物黃金，隨後由基金公司以此實物黃金為依託，在交易所內公開發行基金份額，銷售給各類投資者，商業銀行分別擔任基金託管行和實物保管行，投資者在基金存續期間內可以自由贖回。作為一種在交易所交易的開放式基金，黃金ETF基金的基礎資產是黃金現貨，並以基金份額價格的變動反映黃金現貨減去應計費用後的價格變動為目的。基金持有黃金並可隨時以一攬子數量實現黃金和基金份額之間的交換。值得注意的是，黃金ETF為被動型投資基金，它不能持有或交易高風險的衍生產品，如期貨和期權等。
黃金ETF持倉量很高，所以他們的黃金買進賣出操作一般均會影響黃金市場的價格。一般認為黃金ETF基金持倉量增加，就會利好黃金，對金價的上漲有支撐作用，反之，就是會利空黃金。
