The Shenzhen Stock Exchange (SZSE) has launched a series of ‘Big Data’ indices. The indices have been named the CNI Big Data 100 Index (i100) and CNI Big Data 300 Index (i300).
The SZSE pair of big data indices qualitatively and quantitatively analysed big data that was acquired from the firm SINA Finance. That included, among other factors, the click rate of certain stock pages, the positive and negative influence of news reports and the micro-blog articles.
Using that information, stocks with high gain expectations were selected to form the sample stocks of the indices.
The sample stocks will be adjusted on a monthly basis. From the base day to 29 August, 2014, the total gain of the i100 and i300 are 258% and 161% respectively.
