Investors are demanding more than robust earnings from Samsung Electronics after its recent historic rally, says Charu Chanana, chief investment strategist at Saxo Markets, in a note. After the almost 150% rally so far this year, investors need confident guidance, durable pricing power and proof that AI demand is still accelerating, she says. The key question for Samsung is whether today's memory bottleneck becomes tomorrow's overcapacity risk. Investors will pay attention to Samsung's full 2Q results later this month, and if guidance suggests slower price increases, higher capex, customer caution or weaker visibility, they may start treating memory as a late-cycle trade rather than an early cycle growth story, she adds. Shares closed 6.9% lower at 296,000 won. (sherry.qin@wsj.com)
