Abstract : This paper analyses the influence of Yamaganda period in investor's decision to trade, based on the relationship between Yamaganda timing and Stock trading volume using minuteby minute data(combined fromtick data) of Nifty 200 companies traded at India's National Stock Exchange (NSE) for the period of one year from July 1, 2014 to June 30, 2015 (This period consists of 245 Trading days) and is done using Big data tool Spark. Yamaganda is an Indian cultural variable; it is a time period defined in the astrology which is considered inauspicious. The study is done on Yamaganda period, Non-Yamaganda period, Pre-Yamaganda period (half an hour before Yamaganda Period) amp; Post-Yamaganda Period (half an hour after Yamaganda period). The analysis shows that this cultural variable has very less impact on the Trading decisions of investors. A separate test done only on Tuesday (in order to eliminate day of the week effect and further the absence of Yamaganda period in the trading hours of Wednesday and Thursday) also shows that this cultural variable has very less impact on the Trading decisions of the investors.
