The trading week through Friday, August 14, 2026, was uneven across the observed AI stock catalog. The chip sector stood out most: Broadcom lost 5.5 percent, while competitor AMD gained 3.7 percent – both moves concentrated on Friday’s session. Oracle continued its multi-week downward trend, while German and European stocks barely moved.
Chip sector: opposing swings
Broadcom: -5.5% to $394.81
Broadcom fell on Friday from $417.85 to $394.81. In the in-house stock catalog, no linked event exists for the stock this week. TradingKey reported the same day that there was no fresh company-specific news behind the decline; instead, investors reportedly took profits ahead of the quarterly results scheduled for September 2 and reassessed how much the lower-margin custom AI-chip business would need to contribute to future growth. The drop fits into a skepticism toward semiconductor stocks that has persisted since July, without a single identifiable trigger this week.
AMD: +3.7% to $500.90
AMD rose from $483.09 to $500.90. According to reports from Friday, the company plans to raise fresh capital through a multi-part bond offering of up to five billion dollars. The proceeds are reportedly earmarked partly for the up to $5 billion investment in Anthropic agreed in July. The announcement falls in the same week as AMD’s acquisition of chip startup Taalas – together, both moves paint a picture of a sustained investment push in AMD’s AI business.
Oracle and Nvidia: different reactions to financing news
Oracle: -2.2% to $152.80
Oracle slipped from $156.29 to $152.80. The company had cut jobs again on August 12 to help finance the debt-funded expansion of its AI data centers. In July, rating agency S&P had already downgraded Oracle’s credit rating over OpenAI-related risk. Friday’s decline cannot be traced to a single new event this week, but it fits the pattern of layoff and financing headlines that has persisted for weeks.
Nvidia: +0.1% to $225.62
Nvidia traded nearly unchanged after the company agreed on August 11 with six financial firms on financing platforms worth more than $500 billion for AI data center expansion. The announcement triggered no visible price reaction, and the stock continues trading near its 52-week high of $235.74.
Among German and European stocks, there were no notable swings: SAP gave up 0.2 percent to $208.74 – this refers to the ADR (American Depositary Receipt) traded on US exchanges, not the Frankfurt listing. ASML lost 1.0 percent to $1,829.78. For Siemens, Siemens Energy, Infineon, Aixtron, and Süss MicroTec, the available price data showed no change from the previous day at the time of the query; none of these stocks had a linked event this week.
For the week’s overall picture: the largest swings were not tied to quarterly results but to a financing decision (AMD) and a reassessment with no identifiable fresh trigger (Broadcom). In the coming weeks, two of the observed companies report next: Nvidia on August 26 and Broadcom on September 2.
