| Tiivistelmä: | This paper examines the impact of news on the volatility of equity returns in three sectors of the health care (here as: h-c.) industry: h-c. service providers, producers of drugs and supplies, and third-party payors. The news impact is found to be asymmetric in that bad news (i.e. a negative shock) has a significantly greater effect on volatility than good news. Intra-industry differences in h-c. equity market performance are documented being consistent with the fundamental attributes of these sectors. |
