Asian technology equities are poised to continue setting the tone for regional markets in the third quarter, yet investor behavior is growing more discerning as expensive valuations, patchy earnings and uncertainty over whether the AI spending boom can justify current prices fuel pronounced market moves.
In its most recent Asia technology strategy report, Bernstein said it still prefers semiconductors as a theme, supported by an earnings upgrade cycle that remains robust despite high valuations. The brokerage reiterated its favorable view of several AI infrastructure names - specifically Taiwan Semiconductor Manufacturing (TW:2330), SK Hynix Inc OLD (KS:000660), Samsung Electronics Co Ltd (KS:005930) and MediaTek Inc (TW:2454) - and cautioned investors to prioritize firms with sustainable earnings momentum rather than pursuing costly AI-linked trades.
Market activity on Monday illustrated those investor concerns. South Korea's KOSPI dropped by more than 3%, significantly underperforming its regional counterparts, while Japan's Nikkei 225 declined by over 1%, weighed down by large technology constituents. By contrast, Taiwan's benchmark bucked the broader weakness and rose about 1%, and Hong Kong's Hang Seng advanced roughly 0.5%.
The recent volatility follows investor disappointment after Samsung Electronics' preliminary results failed to reassure markets that memory-chip margins can keep pace with heavy AI-related capital expenditures. That development, combined with several months of outsized gains across parts of the technology complex, has prompted a more cautious stance among investors who are asking whether the billions being invested by hyperscalers in AI infrastructure will translate into sufficient returns.
Bernstein specifically sees AI memory as an important earnings driver in South Korea. The brokerage highlighted SK Hynix's leadership in high-bandwidth memory (HBM) chips - components used in Nvidia's AI processors - as a clear advantage, while noting Samsung Electronics should also benefit materially from the expansion of AI infrastructure spending. Supporting evidence of investor appetite for AI chipmakers was cited in a recent report that SK Hynix's U.S. ADR offering attracted demand in excess of seven times the shares available.
For Japan, Bernstein expressed a constructive outlook toward companies linked to Apple's supply chain, and in particular those connected to MediaTek's ecosystem or makers of electronic components exposed to AI-enabled smartphones and premium consumer electronics. At the same time, the firm maintained an Underperform rating on Kioxia in light of more challenging dynamics in parts of the memory market.
Overall, Bernstein observed that semiconductor stocks have outpaced every other technology subsector so far this year. SK Hynix, Samsung and TSMC have been among the best-performing mega-cap technology names in Asia, a performance the firm attributes to ongoing demand for AI chips and for high-bandwidth memory.
From a regional perspective, the brokerage said it continues to favor Taiwan and South Korea's AI ecosystems, maintaining Outperform ratings on TSMC, SK Hynix, Samsung Electronics and MediaTek. Its approach in Japan and China is more selective - the firm prefers companies that offer clearer earnings visibility and more measured valuations.
Market context and investor takeaway
Investors face a tighter set of criteria when evaluating technology names across Asia. While semiconductors and firms positioned to benefit from AI infrastructure remain core convictions for some analysts, market participants are increasingly focused on earnings durability and valuation discipline as offsetting risks to momentum-driven gains.
Given recent price swings and mixed corporate signals, the emphasis from analysts is to identify companies where AI-related demand translates into sustained profit growth rather than relying on crowded trades that may be priced for perfection.
