(Bloomberg) -- South Korea will hold an emergency meeting Wednesday evening to discuss the market situation after a stocks rout that has wiped billions of dollars off investors' holdings. Lawmakers have linked the rout in part to South Korea's rollout of leveraged single-stock products in May. Still, he maintained that leveraged exchange-traded funds were only one of several factors behind the recent market turmoil. "We've already put in place a package of measures, but if it's needed we'll introduce additional steps to help normalize the market," Koo told lawmakers Wednesday. "The country has turned into a casino," People Power Party lawmaker Lee Jongwook told Koo during the hearing.
