Abstract: The effects of option trading at the DTB on the variance of the underlying stocks are examined. We use a new distribution free test being based on the empirical distribution functions. The evidence indicates that stock return variance increased after the introduction of the DTB. This effect can be partly explained by the strong increase in trading volume for option listed stocks. Our results stand in stark contrast to prior studies of both American and European financial markets.
