我们研究了美国联邦公开市场委员会(FOMC)会议之前和之后的美国市场行为,并表明美国联邦储备委员会(Federal Open Market Committee)宣布利率变化会导致金融冲击,其中宣布利率变化后的动态可用大森地震定律的模拟描述。我们将利率变化后的余震率n(t)定量化,并发现幂律衰减,其尺度为n(t-T)(t-T)^-$\omega$,其中$\omega$为正。令人惊讶的是,我们发现同样的规律描述了在t时刻利率变化之前的“预冲击”的速率n′(t-T)。这是第一个定量地将市场反应的大小与引起冲击的消息联系起来的研究,并揭示了可量化的预冲击的存在。我们证明了与利率变动相关的消息是引起利率变动前的预期和利率变动后的惊喜的原因。我们用美国国库券和联邦基金有效利率之间的相对差来估计金融新闻的幅度。我们的结果符合“符号效应”,即“坏消息”比“好消息”有更大的影响。此外,我们观察到显著的波动余震,证实了至少持续1个交易日的“市场反应不足”。

英文摘要:
  We study the behavior of U.S. markets both before and after U.S. Federal Open Market Committee (FOMC) meetings, and show that the announcement of a U.S. Federal Reserve rate change causes a financial shock, where the dynamics after the announcement is described by an analogue of the Omori earthquake law. We quantify the rate n(t) of aftershocks following an interest rate change at time T, and find power-law decay which scales as n(t-T) (t-T)^-$\Omega$, with $\Omega$ positive. Surprisingly, we find that the same law describes the rate n'(|t-T|) of "pre-shocks" before the interest rate change at time T. This is the first study to quantitatively relate the size of the market response to the news which caused the shock and to uncover the presence of quantifiable preshocks. We demonstrate that the news associated with interest rate change is responsible for causing both the anticipation before the announcement and the surprise after the announcement. We estimate the magnitude of financial news using the relative difference between the U. S. Treasury Bill and the Federal Funds Effective rate. Our results are consistent with the "sign effect," in which "bad news" has a larger impact than "good news." Furthermore, we observe significant volatility aftershocks, confirming a "market underreaction" that lasts at least 1 trading day.
