Asian semiconductor stocks fell sharply on Tuesday as Samsung Electronics’ strong quarterly earnings failed to ease investor concerns over high AI-related valuations.
Asian Chip Stocks Slide Despite Samsung Earnings
The selloff came even though Samsung delivered a strong earnings outlook.
Investors remained cautious about whether the recent surge in AI-driven profits can justify the semiconductor sector’s elevated valuations.
The decline triggered fresh selling across Asia’s memory-chip supply chain.
AI Valuation Concerns Pressure Markets
Demand for AI hardware is still expected to remain strong.
However, after months of major gains in global semiconductor stocks, investors now appear to want stronger proof that heavy AI capital spending can lead to sustainable earnings growth.
This shift in sentiment weighed heavily on chipmakers across the region.
Samsung and SK Hynix Lead Losses
Samsung Electronics, the world’s largest memory-chip maker, dropped nearly 9%.
The decline came after the company forecast a 19-fold increase in second-quarter operating profit.
Despite the strong outlook, many investors chose to take profits after Samsung’s powerful rally this year. The stock has more than doubled so far this year.
Rival memory-chip maker SK Hynix also fell almost 9%.
Asia AI Supply Chain Comes Under Pressure
Weakness quickly spread across Asia’s broader AI supply chain.
Japan’s tech-heavy Nikkei 225 index fell more than 2%.
Murata Manufacturing dropped more than 8%, while LG Innotek lost over 5%.
Taiwan’s MediaTek declined nearly 3%.
Hon Hai Precision Industry, also known as Foxconn, also came under pressure despite reporting stronger-than-expected June and second-quarter revenue, supported by robust AI server demand.
Leveraged ETFs Add to Market Volatility
The selloff also highlighted the growing role of South Korea’s single-stock leveraged exchange-traded funds.
These products aim to deliver multiples of the daily performance of major stocks such as Samsung Electronics and SK Hynix.
When share prices move sharply, ETF issuers must rebalance their hedge positions.
This can create additional selling pressure during market declines.
KOSPI Hit by Memory-Chip Weakness
The mechanical selling linked to leveraged ETFs can amplify losses in both individual stocks and the wider market.
Samsung and SK Hynix have a major influence on South Korea’s KOSPI index.
As a result, weakness in these two stocks weighed heavily on the benchmark, which fell sharply during Asian trade.
Analysts Say Strong Earnings Were Already Priced In
Rajat Agarwal, Asia Equity Strategist at Societe Generale, said Samsung’s earnings were strong but did not deliver a major surprise.
He noted that much of the positive news had already been priced into the stock after its strong rally this year.
Agarwal added that short-term sentiment is currently more important than earnings, especially for memory-chip stocks.
He also said the loss of momentum in chip shares is affecting leveraged ETF flows, adding further pressure to South Korea’s market.
Investors Question AI Profit Sustainability
Vasu Menon, Managing Director of Investment Strategy at OCBC, said the selloff reflects rising doubts over whether exceptional memory-chip earnings can continue.
Investors are becoming more focused on valuations, especially if AI infrastructure spending begins to slow.
This means near-term profits may not be enough to support current share prices.
Fed Minutes and U.S. Earnings in Focus
Attention now turns to the start of the U.S. earnings season.
Investors are also waiting for the minutes from the Federal Reserve’s latest policy meeting.
Both events could provide new clues about technology spending, interest rates, and the broader outlook for risk assets.
