Samsung Electronics and other memory chip makers are more threatened by emerging Chinese competitors than by short-term market moves, says Mikhail Zverev, co-manager of the Amati Global Innovation Fund. "The fact that some hot money got overextended and a bit of a correction is going on today isn't the reason to sell memory stocks," Zverev says. Instead, the competitive threat from emergent memory makers like Yangtze Memory Technologies Co. and ChangXin Memory Technologies will challenge the industry's status quo, Zverev says. "We're still holders of Samsung Electronics, but we're a lot more nervous holders than we were this time last year." (josephmichael.stonor@wsj.com)
