Doosan Infracore Co. (042670 KS), South Korea’s biggest construction-equipment maker, climbed 3.7 percent to 29,600 won, the highest close since April 8. The company said first-quarter operating profit increased 69 percent and that it agreed to sell its forklift business.

First-quarter profit rose 23 percent to 757.6 billion won ($707 million) as lending margins widened and bad-loan provisions fell, according to a filing from the company.

The company said consumer- electronics sales may stay muted in the second quarter. Samsung reported a 30 percent drop in first-quarter net income as competition drove down prices.

Seoul Semiconductor Co. (046890 KS) retreated 6 percent to 32,050 won, the lowest close since Aug. 10, 2009. The company’s lowered profit guidance prompted Daewoo Securities Co. and LIG Investment & Securities Co. to cut their share-price estimates.
