K-pop boy band BTS has climbed to the top of U.S. Billboard charts, appeared on the Tonight Show Starring Jimmy Fallon and is in the middle of a sell-out world tour that’s taking them through 12 countries, including the U.S. and England.
But while the energetic dance group may be riding high, other K-pop stars are finding it harder to reach global stardom in a crowded field. Shares of JYP Entertainment Corp., the agency behind girl group "Twice," slid a record 20 percent in Seoul Wednesday after an analyst said the company is likely to miss earnings estimates. That spurred declines in other agencies too.
