Mobile Informed Trading Leveraging Social Sentiment

Research output: Contribution to conferencePaperResearchpeer-review


Past works exploring the relationship between social sentiment and stock markets have been of great interest to investors and scholars across multiple disciplines. In this study, we debate whether informed trading is practically connected with social media information even though uninformed trading is commonly linked with social sentiment. We measure the probability of informed trading and perform analysis of covariance on a data set classifying firm cohorts on two trading channels, traditional and mobile. The results show that the influence of positive sentiment on informed trading is statistically significant for well-known firm group on the mobile channel. However, negative sentiment and other factors do not affect the informed trading in the same setting. This implies that social media is likely to be a channel for mobile informed trading, which is different from previous research. This study offers new insights into the economic impact of social media on the informed trading.
