In the current scenario, every investor has to be alert to local information as well as glocal (global and local) news and cues. Social media and microblogging are some online platforms where the information is shared and gathered quickly involving less cost. Twitter is one such platform, where brief updates are available to the public or a selected circle of contacts. It conveys the author's mood and emotional status. Hence, the content can be regarded as a valid indicator for a temporary, authentic and instantaneous public mood state. The posting of news on social media also triggers stock market movements due to the knee-jerk reactions caused by investor sentiments. This study tries to find the relationship between the sentiments and global cues with respect to the Indian stock market. The large-scale data analysis gives a strong base to witness and predict values by taking into consideration the emotive moods and trends associated with social and economic indicators.
