The initial raw daily data can be downloaded from Here. Caution this data set is very large about 330mb and consist of 3147312 rows and 14 colums. The data includes 1035 unique TIC id for firms. Running the [Data_clean.py][Data_clean.py] will produce a clean pickle file namely daily_clear_ret.pickle with pandas data frame. The clean data shape is (928773, 27), with 25 features and TIC and CUSIP as identifying variable.

A Keras implementation of the Dy-Gap model proposed in the paper is presented in Dy_Gap_Model.ipynb.

The iPython Notebook Figures_and_Statistics.ipynb provide the related network statisitcs and their distribution. It also recreate some of the Figures from the paper.

Green represents positive edges and red represents negative edges. During the normal economic condition, the market consists of a mixture of positive and negative edges. However, during the economic or political event, the network is dominated by positive edges, representing the commonality across firms.
