Korea's biggest brokerages

Local brokerage houses have sharply revised down their estimate for the third-quarter operating income of Samsung Electronics Co., citing weak performance in the smartphone sector, an online financial information provider said Wednesday.
South Korea's 27 brokerage houses estimated Samsung's operating profit for the July-September period at 6.98 trillion won (US$6.85 billion), hovering far below the 8.6 trillion won outlook made in July, the data compiled by FnGuide showed.
