[In-Depth Analysis] Worsening Sentiment in Semiconductor Stocks: Disappointing Global Guidance and Profit-Taking

Global Guidance Disappointment and Dampened Sentiment

Investment sentiment has cooled rapidly in recent days, particularly surrounding semiconductor stocks in both domestic and global markets. The most direct catalyst is the conservative forward guidance provided by major global semiconductor companies. Despite Broadcom reporting solid earnings in early June that met market expectations, the company maintained a cautious stance on its future guidance. Market participants reacted sensitively, interpreting this as a 'peak-out' signal that semiconductor demand may have reached its zenith. Furthermore, Micron's projection that the memory semiconductor sector might hit its cyclical peak by mid-next year has amplified investors' skepticism regarding the sustainability of the semiconductor 'super-cycle' that has been leading the broader market.

Resurgence of AI Bubble Fears and Aggressive Profit-Taking

Adding to the downward pressure is the resurgence of AI bubble fears centered around Wall Street. While the market has historically cheered the expansion of AI infrastructure investments led by companies like Nvidia, fundamental skepticism is currently spreading over whether these massive capital expenditures (CAPEX) are translating into adequate profitability for Big Tech companies. This psychological contraction has triggered aggressive profit-taking across the entire semiconductor sector, which had previously driven steep index gains fueled by AI momentum. The market volatility has been further exacerbated by retail investors' capital, which had heavily flowed into leveraged ETFs and derivative products for short-term gains, creating cascading sell pressure during the downturn.

Decline of Domestic Tech Giants and the Vicious Cycle of Supply and Demand

These adverse global macroeconomic conditions immediately impacted the domestic market. As of June 5, South Korea's twin semiconductor pillars, Samsung Electronics and SK Hynix, experienced synchronized weakness driven by strong foreign selling pressure. Massive net selling by foreign investors weighed heavily on the KOSPI index, acting as upward pressure on the USD/KRW exchange rate. This dynamic has created a negative feedback loop, where a higher exchange rate further stokes foreign investors' fears of FX losses, incentivizing additional capital flight. Ultimately, the current price correction in semiconductor stocks appears to be less about a structural collapse of industry fundamentals and more indicative of a consolidation phase—a normalization of previously overheated market expectations compounded by short-term macroeconomic uncertainties.
