Samsung Crash Drags Semiconductor Sector Down: Nvidia Earnings on Aug 26 in Focus

Samsung Electronics shares crashed 8.7% on August 24, 2026 in Seoul, triggering a selloff in the global semiconductor sector. The plunge followed the announcement of a shareholder distribution plan worth 90–100 trillion won (roughly €61–67 billion) – a classic sell-the-news reaction after the stock had risen in anticipation of the plan.

Why Samsung Fell Despite Record Payouts

Although investors generally welcomed the unprecedented payout volume, the plan's specific design disappointed. Market participants had expected a more aggressive immediate share buyback. Additionally, the lack of a concrete timeline for treasury stock cancellations left institutional investors underwhelmed.

While South Korean retail investors seized the weakness as a buying opportunity, foreign institutional investors sold their positions. This pattern reflected differing assessments of the program's strategic significance.

Sympathy Selling Grips US Semiconductors on August 24

The Samsung crash spilled into US markets on the morning of August 24, 2026. Semiconductor stocks fell in sympathy selling despite no fundamental corporate news from the US. The NASDAQ Composite lost 0.76% to 25,980.19 points (as of August 25, 2026, 12:03 UTC), while the S&P 500 gained 0.43% to 7,690.63 points.

On the evening of August 24, pressure on Asian markets intensified: South Korea's KOSPI Index fell nearly 2%, driven by semiconductor declines and heavy selling by foreign investors. These sales occurred immediately ahead of Nvidia's quarterly earnings release, scheduled for August 26, 2026 after US market close.

Nvidia Earnings on August 26 as Key Catalyst

Analysts view Nvidia's quarterly earnings as more significant for the broader market than Samsung's stock moves. Nvidia, the dominant supplier of AI accelerator chips, serves as a gauge for artificial intelligence momentum and hyperscalers' investment appetite—companies like Microsoft, Amazon, and Google.

Expectations are high: After a year of spectacular revenue and earnings growth driven by the AI boom, investors are closely watching whether Nvidia can meet or exceed consensus estimates. A disappointment could put further pressure on the semiconductor sector.

As a secondary but relevant data point, Marvell will report quarterly results on August 27, 2026 after US market close. Marvell, a maker of networking and storage chips for data centers, provides insights into the next phase of AI infrastructure investments.

Semiconductor Sector Lost Over $1 Trillion in Late July

The current selloff follows a series of setbacks weighing on the semiconductor sector since late July 2026. At the end of July, global semiconductor stocks lost more than $1 trillion in market capitalization. Nvidia, SK Hynix, Samsung Electronics, Micron, AMD, and TSMC each shed over $100 billion in market value.

On July 28, 2026, semiconductor stocks fell following weakness in Asian and European markets: Intel closed nearly 6% lower, AMD lost 8%. On August 19, 2026, Samsung Electronics and SK Hynix plummeted in Seoul by more than 7% temporarily; the Philadelphia Semiconductor Index fell 5% and posted its weakest trading day since late July.

These earlier selloffs were triggered by concerns about looming US interest rate hikes and massive AI investments, with profit-taking ahead of major earnings dates playing a role.

Technical Analysis: SOXL ETF Approaches Oversold Territory

The Direxion Daily Semiconductor Bull 3X ETF (SOXL) – a leveraged product popular with speculative investors ("momentum crowd") – showed the following technical patterns on August 24, 2026: The price rallied to the lower band of Zone 2 (resistance) but failed to sustain the rally to the upper band, which was viewed as a negative signal.

The price then retreated to the upper band of Zone 3 (support). The Relative Strength Index (RSI) – a momentum indicator showing overbought or oversold conditions – approached oversold territory, suggesting a possible near-term rebound.

Risk: Weak Demand for Anthropic's Fable 5

An additional risk factor for the AI trade remains largely overlooked: Anthropic's AI model Fable 5 has seen weaker-than-expected demand. Analysts view this as a major risk to the entire AI trade, though the broader market has largely ignored this signal. Declining demand for AI services could dampen investments in AI infrastructure and thus demand for high-performance chips.

Trade Policy Tensions Add Pressure

Parallel to the semiconductor selloff, US-Canada trade negotiations broke down on August 24, 2026. Canada suspended talks. Starting at midnight on August 24, the US was set to impose 50% tariffs on $28 billion in goods. The Canadian government planned to mirror the tariffs to protect domestic businesses and consumers.

Although these tariffs do not directly affect the semiconductor sector, they amplify broader uncertainty about global supply chains and trade policy – factors that matter for a highly globalized sector like semiconductors.

Outlook: Structural Market Changes Starting December

The New York Stock Exchange (NYSE) and Nasdaq plan to expand to 23-hour daily equities trading beginning December 6, 2026. This expansion aims to attract foreign investors, particularly from Asia, and generate additional trading volume. However, analysts warn this would increase risk for most investors, as price moves in thinly-traded sessions can be more pronounced.

For European investors, this means further overlap of trading hours: While DAX shares gained 0.78% to 26,318.5 points on August 25 and the Euro Stoxx 50 rose 0.32% to 6,475 points, the future 23-hour opening of Asian and US markets could create new risk management challenges.
