我们使用 2001 年至 2009 年的大样本,其中包含来自 39 个交易所的日内交易数据和平均 12,800 种不同的普通股,来评估算法交易 (AT) 对公司融资活动的影响。更大的 AT 减少了明年的净股本发行,但这只是部分由 AT 对新证券发行收益的影响推动的。我们的研究结果表明,这种关系的主要驱动力是 AT 对股票回购的影响。
We use a large sample from 2001 to 2009 that incorporates intraday transactions data from 39 exchanges and an average of 12,800 different common stocks to assess the effect of algorithmic trading (AT) on firms’ capital raising activities. Greater AT reduces net equity issues over the next year, but this is only partly driven by AT’s effect on proceeds from new securities issues. Our findings suggest that the main driver of this relationship is AT’s effect on share repurchases.
