The Ibex 35 closed on Thursday at 19,177.70 points, after accumulating a drop of over 3% during the week. The sale of semiconductors in Asia and Europe marks the session on Friday, October 16, 2026.
According to information published by euribor.com.es, the Ibex 35 opens the session on Friday, October 16, 2026, after its worst week since April. The index has accumulated a drop of over 3% and closed on Thursday at 19,177.70 points, with a decline of 0.28% in the last session, according to El Español.
In early trading, the Madrid selective index remained slightly above its European counterparts, with a rise of 0.2% to 19,267 points. Analyst Joan Cabrero from Ecotrader identifies 19,576 points, the highs of October 6, as a key level, and 18,800 points as a potential floor for the correction. Among the stocks weighing heavily against, according to elEconomista, are Ferrovial, Merlin Properties, and Rovi.
The trigger for the week was the massive sale of semiconductors that began on Wednesday on Wall Street and spread to Asia and Europe on Thursday. The South Korean Kospi fell by around 7.6%-8% and the Japanese Nikkei dropped more than 4.9%, according to Valora Analitik and IndexBox. In Korea, SK Hynix lost more than 10% and Samsung Electronics fell 8.73%, according to CNBC.
In Europe, ASML dropped by 6.6% and Infineon Technologies by 9.4%, according to the same source. In the Ibex 35, the technology sector was the main focus of pressure, with declines of between 6% and 7.5% in manufacturers such as Infineon, Soitec, and Aixtron, according to Valora Analitik.
The analysts cited link the drop to two factors: a higher-than-expected inflation figure in the United States, which stood at 3.7%, and a warning from the IMF about Asia's heavy dependence on artificial intelligence. On Wall Street, the Nasdaq Composite fell 1.88% to 26,692.87 points and the S&P 500 lost 1.11%, down to 7,718.94 points.
The euro continues to weaken against the dollar. According to Investing.com, the EUR/USD pair fell to 1.1151 after the September CPI published on October 14, at a 17-month low, and this Friday shows a fragile rebound.
In oil, the price of Brent stood at 104.48 dollars, down 1.49% from the previous close, according to mundopetroleo.com. WTI also declined amid reports that Washington is considering easing sanctions on producers like Russia, Iran, and Venezuela.
