      abstract = {The structural change of financial network of S&P 500 around financial crises from 1998-2012 with 6-months? time window is investigated.  We construct a planar maximally filtered graph from correlations between companies. We calculate the average shortest path and clustering coefficient of the financial networks to observe the change of the network. We found the higher average shortest path before the crises and decreases over time until market enter calm state. However, the average clustering coefficient decreases in the beginning of the crises and increases with the intense of crises. The change of network structure can identify financial states which can be useful for portfolio investment. },
