简单两句about BDI for 新手

tonghu

BDI is an index that measures the price of shipping dry bulk cargo, which includes coal, iron ore, and grain. Since the index is used to gauge the demand for major raw materials used in the early stages of production, it is regarded as a leading indicator for the economy. But this is not complete, the chart below shows the indexed returns of SPX and BDI from 1985. The correlation of monthly changes between the BDI and S&P 500 from January 2007 was 0.33, which is relatively high to suggest some causal relationship. Looking longer term, the correlation of monthly changes was a miniscule 0.07, indicating little or no relationship between the two indices.
