Abstract:
The relation between volume of trade and stock prices has received increasing attention from both academic researchers and market practitioners. Most empirical studies found positive relation between stock-return volatility and volume. The purpose of this thesis is to examine the roles of the number of trades, size of trades, and order imbalance in explaining the volatility-volume relation for samples of NYSE and NASDAQ stocks from the TAQ database. We estimate the modified Two-Stage Least Square model of Jones et.al (1994). Our results reconfirm the significance of the size of trades, beyond that of the number of trades, in the volatility-volume relation on both markets. After controlling for the return impact of order imbalance, the volatility-volume relation becomes much weaker, and order imbalance is not a non-rational persistent phenomenon. Additionally, on the competitive structure of NASDAQ the effect of recent market reforms has improved the competitive and microstructure significantly.
