Eunice, thanks for bringing this article to our attention. I found it too dense with unfamiliar, non-standard terminologies, and the “findings” to be difficult to reconcile with any of the three versions of the efficient market hypothesis. So, I downloaded the abstract. Same even more densely defined terminology and unexplained conclusions. So, I downloaded the paper. It was a little easier to understand, but all its breathless “mirabile dictu” conclusions appear to be tenuous and of little value in predicting future market changes in a timely and useful manner. So, now I quote the opening summary paragraph that purports to provide an introductory summary and I welcome any comments that can decipher its meaning. “Several studies have documented that the sentiment of news text forecasts short-term changes in asset prices, with negative news forecasting negative returns. We find that a change in the distribution of news text— a measure of the novelty or unusualness of the news rather than its sentiment—forecasts negative market returns and macroeconomic outcomes over the subsequent year. Consistent with this pattern, we find that assets that positively covary with our measure carry a negative risk premium: investors accept lower compensation to hold assets that hedge the risk associated with a shift in the language of news.” For all my effort I concluded that the paper says that strange terminologies create negative sentiments that drive down interest in investments after up to a one-year delay. How that falls within the concept of something "useful" to know escapes me. I concluded that the article seems to be a self-referential tautological certainty and that someone needed to publish anything anywhere near AI to keep their jobs. I haven't had this much fun since "Godel, Esher, Bach" in the1970s. Any Indiana Jones' out there?

This from the same class of pointy-heads that developed the "volatility-is-risk" fantasy.
