Previous research on R-square has focused on the cross-sectional effects of the level of R-square and the results are mixed. We argue that changes in R-square can capture how new information is incorporated into stock prices. We examine the changes in R-square and stock price synchronicity upon compliance disclosures of earnings and regulatory reprimanding disclosures of "special treatment" status in China. Our results show that upon information arrival, R-square decreases because of the increase in firm-level information from the announcements, a result that is consistent with our hypothesis. Moreover, the market is more reactive in pricing bad rather than good news.
