股票收益率横截面的日内形态

Intraday Patterns in the Cross-section of Stock Returns

Steven L. Heston, Robert A. Korajczyk, Ronnie Sadka

摘要:

受投资流和最优交易文献的启发,我们研究了股票收益横截面的日内可预测性。我们发现了一个惊人的模式,即以半小时为间隔的回报持续,这是一个交易日的确切倍数,这种影响至少持续了40个交易日。成交量、订单失衡、波动性和买卖价差表现出类似的模式,但不能解释收益模式。我们还表明,短期回报逆转是由持续不到一个小时的临时流动性失衡和买卖反弹驱动的。择时交易可以减少相当于有效价差的执行成本。

英文摘要:

Motivated by the literature on investment flows and optimal trading, we examine intraday predictability in the cross-section of stock returns. We find a striking pattern of return continuation at half-hour intervals that are exact multiples of a trading day, and this effect lasts for at least 40 trading days. Volume, order imbalance, volatility, and bid-ask spreads exhibit similar patterns, but do not explain the return patterns. We also show that short-term return reversal is driven by temporary liquidity imbalances lasting less than an hour and bid-ask bounce. Timing trades can reduce execution costs by the equivalent of the effective spread.
