New York, 25 June 2026 – Wall Street ended mixed on Thursday as declines in megacap technology stocks outweighed strong gains in semiconductor counters, leaving investors caught between renewed optimism over artificial intelligence chip demand and concern over stretched valuations.
The Dow Jones Industrial Average closed slightly higher, while the Nasdaq Composite declined and the S&P 500 finished nearly flat. The mixed session reflected a market still willing to reward companies with strong AI-linked earnings visibility, but increasingly cautious towards large technology names facing margin pressure, pricing concerns and elevated expectations.

Micron Technology was the standout performer after the memory-chip maker delivered an upbeat outlook that reinforced confidence in demand for AI-related hardware. Its shares surged as investors responded positively to signs of strong demand for memory products used in data centres, servers and advanced computing systems.
The rally in Micron also lifted broader semiconductor sentiment. Chip stocks have become one of the most important drivers of global equity performance this year, as investors continue to bet on rising demand for AI infrastructure. The Philadelphia semiconductor index gained strongly, supported by renewed buying interest in memory, processor and hardware-linked names.
However, the strength in chipmakers was not enough to carry the wider market higher. Apple fell sharply after raising prices for selected MacBooks and iPads in response to soaring memory and storage costs. The move raised concerns that higher component prices could test consumer demand and squeeze parts of the consumer electronics market.
Other megacap technology names also came under pressure, including Nvidia, Microsoft and Alphabet. Their declines weighed heavily on the Nasdaq and kept the broader market from fully benefiting from the upbeat semiconductor outlook.
The session showed that investors are becoming more selective within the technology sector. Companies directly benefiting from AI infrastructure spending may still attract strong buying interest, but firms exposed to rising input costs, weaker consumer demand or valuation pressure face closer scrutiny.
The market also had to absorb fresh economic data. Inflation remained a key concern as investors assessed whether price pressures could push the Federal Reserve towards a more hawkish policy stance. Stronger economic data can support earnings expectations, but it can also increase the risk that interest rates stay elevated for longer.
This creates a challenging backdrop for growth stocks. Higher interest rates reduce the present value of future earnings, which can pressure high-valuation companies even when their long-term growth prospects remain strong.
The divergence between semiconductor strength and megacap weakness highlights the changing nature of the AI trade. Earlier in the rally, investors bought broadly across technology. Now, they are beginning to separate companies with immediate earnings support from those where AI expectations may already be priced in.
For global markets, the mixed Wall Street finish may shape trading sentiment across Asia. Semiconductor-linked markets such as South Korea, Taiwan and Japan could draw support from the chip rally, while broader technology sentiment may remain cautious if megacap weakness continues.

Wall Street’s mixed close sends an important signal to Asian investors: the AI trade remains alive, but it is becoming more selective.
Micron’s strong performance shows that investors are still willing to reward companies with direct exposure to AI hardware demand. Memory chips, high-performance computing components, data-centre infrastructure and advanced semiconductor equipment remain key areas of market interest.
However, Apple’s decline shows the other side of the AI boom. Rising memory and storage costs may benefit chip suppliers, but they can hurt consumer electronics makers that depend on those components. This creates a clear split between upstream winners and downstream companies facing higher input costs.
For Asia, this matters because the region sits across the full technology value chain. South Korea, Taiwan and Japan have major semiconductor exposure, while Malaysia and Southeast Asia play important roles in testing, assembly, electronics manufacturing, precision engineering and data-centre support.
Malaysian investors should watch whether AI-driven component demand continues to support the electrical and electronics sector, while also monitoring whether higher costs begin to affect global device demand. A slowdown in consumer hardware upgrades could affect parts of the supply chain even if AI infrastructure demand remains strong.
The latest Wall Street session suggests that technology markets are moving into a more disciplined phase. AI remains the dominant growth theme, but earnings delivery, cost control and valuation discipline will determine which companies continue to lead.
