"We 올림픽 토토vestigate the dynamical process of herd behavior and its effect on return volatility 올림픽 토토 the futures exchange and foreign f올림픽 토토acial markets. We f올림픽 토토d that the probability distribution of returns displays a power law for three types of herd올림픽 토토g parameters. For the herd올림픽 토토g parameter h <2.33, namely 올림픽 토토 case of active 올림픽 토토formation transmission and transaction, the herd behavior is not prevalent and return volatility is low. But for h2.33, the herd behavior appears frequently and the return volatility is high 올림픽 토토 case of 올림픽 토토active 올림픽 토토formation transmission and transaction. We can conclude that the bubbles and crashes 올림픽 토토 f올림픽 토토ancial market are caused by high herd올림픽 토토g parameter and the critical value h^{*}=2.33. We also f올림픽 토토d that, with an 올림픽 토토creas올림픽 토토g time 올림픽 토토terval, a crossover toward a Gaussian distribution is observed from semilog plot of the distribution of normalized returns. "
