摘要：

We study the evolution of the correlation-based clusters of stocks, which usually accord with business groups. By segmenting the whole time series into several overlapping segments, we trace the dynamical evolution of each business sectors in terms of the multi-factor model and especially treat the stock prices of Shanghai composites that are not incorporated into developed markets of the financial time stock exchange index.
