Intraday Price Change and Trading Volume Relations in the Stock and Stock Option Markets
研究1986年第一季度CBOE期权交易样本中，股票与期权日内价格变化和交易量的领先滞后关系，发现股票市场价格变化领先期权市场最多15分钟。
ABSTRACT This study investigates intraday relations between price changes and trading volume of options and stocks for a sample of firms whose options traded on the CBOE during the first quarter of 1986. After purging the price change series of the effects of bid/ask spreads, multivariate time‐series analysis is used to estimate the lead/lag relation between the price changes in the option and stock markets. The results indicate that price changes in the stock market lead the option market by as much as fifteen minutes. The analysis of trading volume indicates that the stock market lead may be even longer.
