April 13 (Bloomberg) -- Shares of the following companies had unusual moves in South Korea trading. Stock symbols are in parentheses and prices are as of the close in Seoul.
The Kospi Index rose 1.1 percent to 2,008.91. The gauge fell 1 percent this week, the most since the week to Jan. 1.
Defense-related companies: Victek Co. (065450 KS), a maker of electronic warfare equipment, tumbled 13 percent to 2,350 won. Speco Co. (013810 KS) lost 10 percent to 2,800 won, while Huneed Technologies (005870 KS), a military communication equipment maker, sank 10 percent to 3,510 won. North Korea defied international condemnation and launched a rocket today that failed minutes after liftoff.
“If the rocket launch was successful, the international community especially the U.S. would have put even more pressure on the North,” Choi Hyun Jae, an analyst at Tong Yang Securities Inc., said by phone today. “The failure removes some of the steam here. Investors who bought defense stocks ahead of the launch are also taking some profits.”
Hynix Semiconductor Inc. (000660 KS), the world’s second-largest maker of computer memory chips, rallied 6.6 percent to 29,000 won, the most since Feb. 28. A recent share-price drop and better-than-expected first-quarter personal-computer shipments are driving the stock higher, Choi Do Yeon, an analyst at LIG Investment & Securities Co., said by phone. The global personal-computer industry unexpectedly grew in the first quarter, according to data from Gartner Inc.
There’re also expectations that prices for dynamic random access memory chips will rebound starting from mid-May, Brian Park, an analyst at Tong Yang Securities Inc., said by phone.
