Abstract:
I introduce a novel approach for the empirical analysis of asset price comovement that relates the inter-firm textual similarity of news reports to their equity return correlation. I find that this measure of news similarity is just as important for predicting future cross-firm comovement as contemporaneous return correlation. This predictability remains after controlling for industry correlation, size, book-to-market, momentum, and price-decile correlation, index membership, and headquarters location, as well as institutional holding and analyst coverage. These results contribute to the growing literature examining the role of the media in financial markets, and provide empirical support for an alternative description of return comovement that does not depend on friction-based explanations such as "category," "habitat," or "information diffusion."
