大宗商品股票，其實還有不少是可以逆勢投資考慮的。
例如：
◎必和必拓(BHP
Billiton Ltd)BHP
◎力拓(Rio
Tinto Group)RIO
◎英美資源集團
(Anglo American) (LON:AAL)
三者中，以Anglo
AmericanL長期債務最高，經營效率AAL最低，RIO其次，BHP最好。
因此若漲時，AAL和RIO比較有機會漲多些。
不過，我認為大宗商品股票不需要購買太多，因為起不了分散風險效果。
只需要集中在【金，銀，油，糧食】四個領域的股票就可以了！
因為糧食股票很難買，所以只能折衷購買【農產品ETF】。
【農產品ETF】幾乎主要都是通過金融衍生產品來追蹤農產品期貨價格的。
而不是買農產品生產公司的股票，實際上這類股票也很難找。
目前，我比較傾向於多元化不同農產品的#【PowerShares/DB

這圖表是中國股市MARGIN數額。中國股市早在２０１４年突然飆漲，是中國政府的傑作，大量的MARGIN推高了股市。
後從５０００點啟動暴跌的時候，我說過，這些MARGIN數額若不回到平時水平，下跌就不會結束。
目前看MARGIN數額，仍距離正常水平有段距離，仍有的跌。
