英文摘要:
In this article we use the Mean-Variance Model in order to measure the current market state. In our study we take the approach of detecting the overall alignment of portfolios in the spin picture. The projection to the ground-states enables us to use physical observables in order to describe the current state of the explored market. The defined magnetization of portfolios shows cursor effects, which we use to detect turmoils.

中文摘要:
在本文中,我们使用均值-方差模型来衡量当前的市场状态。在我们的研究中,我们采用的方法是在旋转图中检测投资组合的整体对齐。基态的投影使我们能够使用物理观测来描述所探索市场的当前状态。定义的投资组合磁化显示光标效应,我们用它来检测动荡。
