Mood and the Market: Can Press Reports of Investors’ Mood Predict Stock Prices?

We examined whether press reports on the collective mood of investors can predict changes in stock prices. We collected data on the use of emotion words in newspaper reports on traders’ affect, coded these emotion words according to their location on an affective circumplex in terms of pleasantness and activation level, and created indices of collective mood for each trading day. Then, by using time series analyses, we examined whether these mood indices, depicting investors’ emotion on a given trading day, could predict the next day’s opening price of the stock market. The strongest findings showed that activated pleasant mood predicted increases in NASDAQ prices, while activated unpleasant mood predicted decreases in NASDAQ prices. We conclude that both valence and activation levels of collective mood are important in predicting trend continuation in stock prices

Envy: An adversarial review and comparison of two competing views

The nature of envy has recently been the subject of a heated debate. Some researchers see envy as a complex, yet unitary construct that, despite being hostile in nature, can lead to both hostile and non-hostile reactions. Others offer a dual approach to envy, in which envy’s outcomes reflect two types of envy: benign envy, involving upward motivation, and malicious envy, involving hostility against superior others. We compare these competing conceptualizations of envy in an adversarial (yet collaborative) review. Our goal is to aid the consumers of envy research with navigating the intricacies of this debate. We identify agreements and disagreements and describe implications for theory, methodology, and measurement, as well as challenges and opportunities for future work
