商品市场的相关性

Correlations in commodity markets

Paweł Sieczka, Janusz A. Hołyst

摘要:

在本文中,我们分析了商品市场的相关性,调查1998年9月1日至2007年12月14日期间商品期货合约的相关性。基于相关矩阵构造了一棵最小生成树。该树为所调查合同的部门聚类提供了证据。我们还研究了商品依赖的动力学性质。结果表明,在研究期间,市场的相关性不断增强,尽管相关性的增加在所有合约中分布不均匀,并且取决于合约分支。

英文摘要:

In this paper we analyzed dependencies in commodity markets investigating correlations of future contracts for commodities over the period 1998.09.01 - 2007.12.14. We constructed a minimal spanning tree based on the correlation matrix. The tree provides evidence for sector clusterization of investigated contracts. We also studied dynamical properties of commodity dependencies. It turned out that the market was constantly getting more correlated within the investigated period, although the increase of correlation was distributed nonuniformly among all contracts, and depended on contracts branches.
