Asian technology shares moved sharply as investors balanced two competing signals: a global risk-off move in AI and semiconductor stocks, and the possibility that the underlying chip cycle remained intact. Overnight losses on Wall Street and caution before Nvidia’s results pushed shares lower initially, while later buying reflected a less severe reassessment of AI demand and valuation risk.
U.S. technology stocks had already weakened, pulling the Nasdaq 100 lower and extending pressure on semiconductor names. Asian investors followed that lead, reducing exposure to chipmakers ahead of a week dominated by Nvidia’s earnings and the Federal Reserve’s annual gathering. The regional MSCI equity gauge fell 0.5% in the selloff, with Samsung Electronics and Alibaba among the largest contributors to the decline. 2

Nvidia’s seven-session losing streak made the market especially sensitive to any sign that AI spending might not justify the sector’s elevated valuations. Japanese chip-related shares tracked their U.S. peers lower as investors waited for Nvidia’s May–July report, which was expected to be a major test of global AI-demand expectations. 26
28
Samsung’s shareholder-return announcement intensified the pressure on the KOSPI. The company guided to 90 trillion won to 110 trillion won in shareholder returns for the year, including 30 trillion won in third-quarter cash dividends. 18
21
That was a record-sized package, but the market reaction was negative because investors had expected a larger share of Samsung’s AI-related cash generation and more detail on buybacks or share cancellations. Samsung shares fell more than 8% in early trading after the announcement, adding a company-specific drag to a benchmark heavily influenced by technology and memory-chip companies. 18
19
The disappointment was not simply about the absolute payout. Investors were also judging how Samsung intended to distribute the cash and whether the policy offered enough clarity about future returns. That helps explain why a seemingly large package could still trigger selling.
The market was not waiting only for Nvidia’s reported revenue. It was also looking for evidence that demand for AI infrastructure could continue to support high semiconductor valuations and strong forward guidance.
Analysts were reported to expect Nvidia’s quarterly revenue to approach $92 billion, with growth expected to be close to doubling year over year. 28 A result that merely met the headline estimate might therefore be insufficient if the outlook or margins disappointed. Conversely, strong guidance could reassure investors across Asia because companies such as Samsung, SK Hynix and Japanese chip-equipment and data-center suppliers are exposed to the same AI investment cycle.
This is why the early decline did not necessarily signal that investors believed AI demand had collapsed. It also reflected crowded positioning, elevated expectations and the risk of holding semiconductor shares immediately before a market-moving earnings release.
As the initial shock was absorbed, investors began distinguishing between a short-term positioning reversal and a fundamental deterioration in the chip market. That encouraged dip-buying in Samsung and SK Hynix and supported a broader recovery in Japanese AI- and semiconductor-linked shares.
Japanese names including Kioxia, Advantest, SoftBank Group and Furukawa Electric had been among the shares hit by the technology-led selloff. In the subsequent rebound, Furukawa Electric was one of the strongest gainers, while the Nikkei 225 also recovered from its earlier weakness in the session described by market coverage. 27
The moves show how closely regional indexes were trading as a basket of AI-infrastructure exposure. South Korea’s KOSPI was particularly sensitive to Samsung and SK Hynix, while Japan’s Nikkei was affected by chip-related companies and other technology-linked names.
The second major variable was the bond market. Higher U.S. Treasury yields had been weighing on the KOSPI and on technology valuations, while investors monitored whether rates would ease and reduce pressure on long-duration growth stocks. 9
Markets were also preparing for Federal Reserve Chair Kevin Warsh’s remarks at Jackson Hole. A less-hawkish signal could support lower yields and improve the appeal of technology shares; a hawkish message could renew the valuation pressure. 4

That makes the rebound difficult to interpret as a clean all-clear signal. It was better understood as a repricing around two imminent catalysts: Nvidia’s earnings and the Fed’s interest-rate guidance.
The session combined four forces:
The best reading is therefore a “sell first, reassess later” session. The opening decline reflected global technology weakness and company-specific disappointment; the recovery reflected investors deciding that Nvidia’s earnings risk and the semiconductor cycle had not yet been decisively damaged. But with a roughly $92 billion revenue expectation and the Fed’s Jackson Hole remarks still ahead, the rebound remained highly dependent on incoming evidence rather than conviction that the AI trade was safe.
