The effects are asymmetric: negative changes in the Dow-Jones Index returns have twice the effect than positive ones; and nonlinear as the influence of Black Friday, October 13, 1989 suggests. The "meteor shower" effects between boths markets volatilities is documented. Daily traing volume has some explanatory power for the conditional variance of daily returns.
