Samsung Shares Plunge Despite Record Profits Amid Mounting Capex and Demand Fears

Samsung Electronics experienced a surprising downturn in its stock performance, with shares plummeting nearly 7% on Tuesday, despite the tech giant reporting a preliminary record-shattering second-quarter operating profit. The company announced an impressive 89.4 trillion won ($58.4 billion) in operating profit for Q2, a significant leap from 57.2 trillion won in the previous quarter and an astonishing 1,800% increase year-on-year. Revenue for the April-to-June period also soared to 171 trillion won, more than doubling sales from the same period last year.

Despite these stellar financial figures, investor sentiment was clouded by growing concerns over future capital expenditure and a potential softening in demand, particularly for high-bandwidth memory (HBM) chips critical for the booming AI infrastructure market. Zavier Wong, a market analyst at eToro, commented that the market had already priced in a "historic quarter" for Samsung. He noted, "once the numbers confirmed it was significant but not far beyond what the market had already expected, there wasn't much to reward anyone stepping in... confirmation is what people sell into." Wong added that fears about the sustainability of AI infrastructure spending, which has been a key driver of memory prices, are weighing on the stock.

The company's earnings also accounted for one-off expenses related to revised employee bonus provisions. Earlier this year, Samsung agreed to allocate 10.5% of its operating profit towards bonuses, a move that followed weeks of labor union protests demanding a fairer share of the company's prosperity. Tom Kang, a research director at Counterpoint Technology Market Research, suggested to CNBC that a "lot of negative news has been building up," with both the labor union and the Korean government seeking a piece of the burgeoning profits. Kang also highlighted worries that memory prices might have surged too high, potentially dampening future demand, although he confirmed that monthly checks indicate prices for consumer, mobile, and server memory products are still on an upward trend, expected to continue through the current quarter.

Adding to investor anxiety are Samsung's ambitious plans to construct massive new semiconductor fabrication plants in a less conventional, southern region of South Korea. Kang explained that this location, distant from traditional fab concentrations, will necessitate building infrastructure from the ground up, deviating from investor expectations and being perceived as less suitable for high-tech facilities.

Competition is also a factor, with domestic rival SK Hynix's upcoming American Depositary Receipt (ADR) listing this week drawing some investor attention away from Samsung. Wong noted, "It doesn't help that SK Hynix's ADR listing lands the same week, pulling some of that rotation appetite elsewhere."
