Abstract
The U.S. Securities and Exchange Commission (SEC) warns professional investors that sentiment analysis tools may lead to impulsive investment decision-making. This warning comes despite evidence showing that aided social sentiment investment decision tools can increase accurate investment decision-making by 18%. Using Fama's theory of efficient market hypothesis, the purpose of this quantitative correlational study was to examine whether customer Twitter comments and employee Glassdoor feedback sentiment predicted successful investing decisions measured by business stock prices. Two thousand records from 3 archival U.S. public NASDAQ 100 datasets from March 28, 2016, to June 15, 2016 (79 days) of 53 companies with over 100 comments were analyzed using multiple linear regression. The multiple regression analysis results indicated no significant predictability for successful investing decisions, F(10, 2993) = .295, p = .982, R2 = .001. The results indicated that the sentiment from both Twitter and Glassdoor was not necessarily an indicator for investors to make successful investment decisions for the 79 days in 2016. The knowledge about Artificial Intelligence (AI) sentiment usage may help professional investors gain profit or prevent losses. A recommendation to investors is to heed warnings from the SEC about tools for sentiment analysis investment decisions. Implications for positive social change include preventing an investor from using a risky sentiment tool for investment decision-making that may lead to losing capital.
