英文摘要:
This paper introduces a non-parametric framework to statistically examine how news events, such as company or macroeconomic announcements, contribute to the pre- and post-event jump dynamics of stock prices under the intraday seasonality of the news and jumps. We demonstrate our framework, which has several advantages over the existing methods, by using data for i) the S&P 500 index ETF, SPY, with macroeconomic announcements and ii) Nasdaq Nordic Large-Cap stocks with scheduled and non-scheduled company announcements. We provide strong evidence that non-scheduled company announcements and some macroeconomic announcements contribute jumps that follow the releases and also some evidence for pre-jumps that precede the scheduled arrivals of public information, which may indicate non-gradual information leakage. Especially interim reports of Nordic large-cap companies are found containing important information to yield jumps in stock prices. Additionally, our results show that releases of unexpected information are not reacted to uniformly across Nasdaq Nordic markets, even if they are jointly operated and are based on the same exchange rules.

中文摘要:
本文引入了一个非参数框架,从统计学上检验了在日内新闻和跳跃的季节性下,新闻事件(如公司或宏观经济公告)如何影响事件前后股价的跳跃动态。我们通过使用以下数据展示了我们的框架:i)标普500指数ETF、SPY,以及宏观经济公告;ii)纳斯达克北欧大盘股,以及计划和非计划公司公告。我们提供了强有力的证据,证明非计划公司公告和一些宏观经济公告会导致发布后的跳跃,还提供了一些证据,证明在计划的公共信息到达之前的跳跃,这可能表明非渐进的信息泄漏。尤其是北欧大型股公司的中期报告,包含了股价上涨的重要信息。此外,我们的结果表明,在纳斯达克北欧市场中,对意外信息发布的反应并不一致,即使它们是联合运营的,并且基于相同的交易规则。
