Outline of Final Research Achievements |
A controversial issue in stock price synchronicity research is whether a lower R-squared reflects a stock price with more information or a noisier stock price. To better understand the properties of R-squared, I focus on the situation in which the information environment drastically deteriorates and examine which view represents a more plausible explanation for R-squared. Using data around an exogenous catastrophic event, namely, the GEJE, on March 11, 2011, I find that, after the event, stock price synchronicity for opaque firms was higher than for transparent firms. The stock prices of opaque firms were not likely to capitalize firm-specific information after the GEJE, which led their R-squared values to increase compared with those of transparent firms. The evidence is more consistent with the hypothesis that a higher R-squared signals that the stock price is deviating from its fundamental value; that is, a lower R-squared reflects a more informative stock price.
