one contract size is 100 futures

NO.PZ2016082404000024

问题如下:

You have a portfolio of USD 5 million to be hedged using index futures. The correlation coefficient between the portfolio and futures being used is 0.65. The standard deviation of the portfolio is 7% and that of the hedging instrument is 6%. The futures price of the index futures is USD 1,500 and one contract size is 100 futures. Among the following positions, which one reduces risk the most?

选项:

A.

  Long 33 futures contracts

B.

  Short 33 futures contracts

C.

  Long 25 futures contracts

D.

  Short 25 futures contracts

解释:

ANSWER: D

To hedge, the portfolio manager should sell index futures, to create a profit if the portfolio loses value. The portfolio beta is 0.65×7%6%=0.758.0.65\times\frac{7\%}{6\%}=0.758.The number of contracts is N=βSF=(0.758×5,000,000)1,500×100=25.3N\ast\text{=}-\beta\frac SF=\frac{-{(0.758\times5,000,000)}}{1,500\times100}\text{=}-25.3 or 25 contracts.

The futures price of the index futures is USD 1,500 and one contract size is 100 futures中one contract size is 100 futures是指的一份 index futures中包含100个小的futures吗?就是那个乘数是吗?

同学你好,对的,100就是那个乘数,这句话的意思其实就是现在future标价是1500,一份合约要买100个,一个contract合计花费是1500*100。
