The fact that the article presents different metrics in response to different inputs (CEO expressions of disgust correlated with 9.3% boost in overall profits over the following quarter, CEO expressions of fear correlated with 0.4% rise in stock price the following week) makes me strongly suspect excessive data-mining.

I haven't been able to find the actual paper in question; it looks like this is the abstract: http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2533615. The lead author's page (https://web.njit.edu/~akansu/journal.htm) lists it as "Journal of Behavioral Finance, to appear, 2017."
