3x etf 的投资组合是石油期权的组合,
各种期权 : futures contracts, options on securities, indices and futures contracts, equity caps, collars, and floors, swap agreements, forward contracts, and reverse repurchase agreements.
所有跟帖:
• 也就是说,3X 油气ETF 反映了油气期权价格的变化,与油气material 的现实价格无关,对吧?谢谢。 -bmwxx- ♂ (0 bytes) () 08/06/2015 postreply 13:59:34
