单项选择题
An analyst does research about commodity markets. Which of the following statements about investing in commodities is least accurate（）
A. Investing in commodity futures is the most common strategy for commodity investing.
B. A collateralized futures position consists entirely of long position in futures for a given amount of underlying value.
C. Commodities tend to have a low to negative correlation with stock and bond retums and a desired positive correlation with inflation.
答案
参考答案：B
解析：
通过期货合约来投资于商品是一种低成本的投资办法，也是商品投资最普遍的方法，所以选项A是正确的。抵押商品期货头寸(collateralized futures position)包括期货合约多头头寸和与头寸等值的国债，所以选项B是错误的。商品与股票和债券的回报的相关性低或者是负相关，与通货膨胀是正相关，商品投资是一种很好的分散化风险和抵御通货膨胀的投资。
