what happened
According to Newsmetry API, the retreat in South Korean semiconductor shares may reflect more than profit-taking: investors are also questioning whether elevated earnings expectations can last through the artificial-intelligence boom. Samsung Electronics was recently down by roughly 9%, while SK Hynix had lost about 10%, leaving both stocks headed toward a fifth straight losing session.
KB Securities analysts E.T. Lee and D.E. Lee wrote that the market still treats semiconductors as a cyclical business and remains unconvinced that the industry can deliver earnings consistently. Supply bottlenecks may produce a sharp profit jump during a boom, they said, but their eventual resolution can create excess inventories and encourage overinvestment. The analysts cited similar developments in diagnostic kits, masks, toilet paper and container shipping after the pandemic.
why it matters
The move highlights the market’s focus on semiconductor cyclicality and on whether current profit expectations can remain durable as the AI boom continues.
