以下是引用sankwok在2010-6-8 23:44:00的发言:
A good hedge of inflation must be storable ! Gas and oil and gold are storable ..people will buy to hedge .....
我从corn改到了GAS,考虑的就是storage cost。
因为记得good hedge should be storable, but my understanding is that gas is very expensive to store and thus is regarded as non-stroable.
难道改错了? |
