Investors are likely slightly disappointed by Samsung Electronics' revenue forecast, according to Morningstar analyst Jing Jie Yu. He notes that Samsung's projected operating profit was in line with market expectations, but the revenue forecast of 171 trillion won was slightly below consensus estimates. The miss was likely driven by more moderate DRAM price hikes than expected, he says. That likely spooked investors increasingly pricing in the structural strength in memory prices, Yu adds. Samsung shares ended 6.9% lower as investors grew more cautious, trimming gains this year to just below 150%. (sherry.qin@wsj.com)
