SEOUL, Nov. 12 (UPI) -- South Korea's leading brokerage houses delivered solid performances in the third quarter of this year, thanks to the recent bullish run in the Seoul bourse.

The Seoul-based company's sales also jumped 22.5% year-on-year to reach $4.55 billion, the largest in the industry.

Korea Investment & Securities said Tuesday that its third-quarter net profit nearly doubled to $413 million, while turnover just edged up 0.4% to $3.85 billion.

Another major player, Samsung Securities, chalked up $1.86 billion in sales, down 1.5% from a year before, for a net income of $211 million, up 28.7%.
