We argue for incorporating the financial economics of market microstructure into the financial econometrics of asset return volatility estimation. In particular, we use market microstructure theory to derive the cross-correlation function between latent returns and market microstructure noise,...

Recent literature documents that analyst recommendations tend to coincide with important corporate events, but offers mixed evidence on whether such recommendations have added value. In this paper, we use jump in stock price as a proxy for generic corporate “information event” and examine...

We develop spectral volume models to systematically estimate, explain, and exploit the high-frequency periodicity in intraday trading activities using Fourier analysis. The framework consistently recovers periodicities at specific frequencies in three steps, despite their low signal-to-noise...

This paper investigates the importance of speed for technical trading rule performance for three highly liquid ETFs listed on NASDAQ over the period January 6, 2009 up to September 30, 2009. In addition we examine the characteristics of market activity over the day and within subperiods...

In a standard four factor framework, mutual fund return volatility is a reliable, persistent, and powerful predictor of future abnormal returns. However, the abnormal returns are eliminated by the addition of a “vol” anomaly factor contrasting returns on portfolios of low and high volatility...

This paper examines how individual investors' participation in short sale affects the efficiency of stock pricing using a unique regulatory change in Korea. The change enables individual investors to sell short some -- but not all -- domestic stocks, without affecting the short-selling ability...

We document the intradaily patterns of return volatility and trading activity in trade times of fixed dollar volumes --- shorter trade times reflect higher trading activity. Unlike the U-shaped intraday seasonality in calendar-time volatility, trade-time volatility plunges by 40-60% over the...

The main objective of this study is to examine if the long term financial trends influence not only a stock market's returns, but also the day of the week pattern (DOW). In order to examine the specific issue we try to find a financial market which: (i) presents clear and long-term financial...
