Samsung’s Record Profit Backfires, Sending a Semiconductor ETF into a 10% Tailspin
Published on 07/08/2026 at 16:58 | Redaktion boerse-global.de
What should have been a banner day for chip investors turned into a rout on Wednesday, as a string of record earnings from Samsung Electronics paradoxically triggered one of the harshest selloffs in the semiconductor sector in months. The iShares MSCI Global Semiconductors UCITS ETF slid to €17.71, wiping out more than 10% in a single week and leaving the fund nearly 18% below its June peak.
The trouble began when Samsung posted preliminary second?quarter results that were nothing short of stellar. The South Korean giant’s operating profit soared 1,810% to 89.4 trillion won (roughly $58.4 billion), while revenue jumped 129% to 171 trillion won. Yet instead of cheering, investors in Seoul dumped Samsung shares by as much as 8%, forcing a 20?minute trading halt on the KOSPI index. The reaction was classic “sell the news”: analysts pointed to a slight revenue miss, growing doubts about the sustainability of the AI memory?chip super?cycle, and a sizable 17 trillion won provision for employee bonuses that weighed on sentiment.
The selling pressure cascaded across global semiconductor names. In the United States, the Philadelphia Semiconductor Index (SOX) suffered its steepest single?day drop in months, falling between 4.6% and 6%. Intel lost more than 10%, closing near $110, while AMD slid about 6.5% as investors questioned lofty price?to?earnings ratios. Micron Technology tumbled as much as 7%, slipping under the $900 mark and below its 50?day moving average. Equipment makers also took heavy hits: Applied Materials dropped roughly 10%, and Lam Research suffered similar losses. In Europe, ASML and Infineon shed 7.3% and 8.3% respectively.
Adding to the unease was a fresh development from China. The AI startup DeepSeek is reportedly designing its own inference chip, aiming to reduce reliance on Nvidia and Huawei hardware. While still in early stages, the news stoked fears of heightened competition in a market already straining under extreme valuation expectations. “Companies are delivering solid results, but they can barely beat the astronomically high bar the market has set,” noted Adam Crisafulli of Vital Knowledge.
The selloff occurred against a backdrop of rising bond yields and geopolitical tension. The yield on the 10?year U.S. Treasury climbed to 4.54% — a three?and?a?half?week high — while the 30?year yield pushed above 5%. Simultaneously, crude oil prices spiked as tensions in the Strait of Hormuz intensified, with WTI approaching $72 and Brent trading near $75.74. This combination fueled a rotation out of growth?oriented tech names into defensive sectors such as healthcare, financials, and consumer staples. The CBOE Volatility Index (VIX) jumped to 16.13, reflecting the sudden spike in market anxiety.
For the iShares ETF, the technical picture has deteriorated rapidly. The fund slipped below its 50?day line at €18.09 and now sits just above what chartists consider critical support near €17. If that level fails, the next downside target is the 100?day moving average at €14.93. Despite the carnage, the fund still carries a year?to?date gain of 79%, and the SOX index remains up 73% for 2026. Many market participants view the 15% correction over four trading days as a healthy consolidation rather than the end of the uptrend.
All eyes now turn to late July, when major U.S. technology companies will report quarterly earnings. Those results will provide a clearer read on whether the massive investment in AI infrastructure can sustain the sector’s momentum — or if the market’s fears of a peak in growth are justified.
