楼主用BDI做为参考来炒股或投资的话,除非是做2个月以上ST。
而且,我认为BDI与SPX没有太多关联性,2008年 ...
"One of the key parameters we watch as being an excellent gauge of global economic direction is the Baltic Dry Index (“BDI”). This measures the amount of cargo circum-navigating the globe and, thus, is a good indicator of the amount of global trade being conducted. It tracks the cost of shipping raw materials around the world in ships of various sizes and, as such, it has become an important indicator of global production and trade. Key commodities currently being shipped include iron ore, coal, and grains, i.e., dry goods."
"In fact, if you compare the S&P 500 index for the past few years with the Baltic Dry Index (BDI), it would seem that shipping rates have lead the equities from 1 to 3 months in both rallies and tops (take a look at the marked points on the chart above)."
