看了一下factsheet,就清楚了,貼給各位看
USO’s Objective –
The investment objective of USO is for daily changes in percentage terms of the shares’ net asset value (“NAV”) to reflect
the daily changes in percentage terms of the spot price of light, sweet crude oil, as measured by the changes in price of the futures contract on
light, sweet crude oil traded on the NYMEX that is the near month contract to expire, except when the near month contract is within two weeks
of expiration, in which case it will be measured by the futures contract that is the next month contract to expire (the “Benchmark Oil Futures
Contract”), less USO’s expenses.
簡單來說,它也是日追型的ETF, 類以什麼二倍 三倍的外匯商品ETF,只是沒有倍數
除非抓到一波超大而且持續的行情,這種日追型的,是討不到便宜的
這也說明了為什麼2009-最近大跌之前,看不出原本石油該有的波動
想玩石油,還是乖乖認命開倉忍受保證金的波動吧
