摘要翻译:
本文利用从2003年中国股票市场交易的23只股票的限价盘账簿中提取的超高频数据,研究了事件时间收益和时钟时间收益在不同微观时间尺度上的分布。我们发现在一个交易时间尺度上的收益服从反比立方律。对于较大的时间尺度(2-32次交易和1-5分钟),回报遵循幂律尾部的学生分布。随着时间尺度的减小,尾部变得更胖,这与振动理论是一致的。

英文摘要:
We study the distributions of event-time returns and clock-time returns at different microscopic timescales using ultra-high-frequency data extracted from the limit-order books of 23 stocks traded in the Chinese stock market in 2003. We find that the returns at the one-trade timescale obey the inverse cubic law. For larger timescales (2-32 trades and 1-5 minutes), the returns follow the Student distribution with power-law tails. With the decrease of timescale, the tail becomes fatter, which is consistent with the vibrational theory.
