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. Multiple financial outlets pointed to a specific trigger: reports of active attacks exploiting a critical security flaw in VMware’s vCenter Syslog Server (CVE-2026-59310). Broadcom had disclosed the flaw on July 29, researchers say attackers have actively exploited it since August 3, and roughly 361 IP addresses across 47 countries were affected (Yahoo Finance). TradingKey reported the same day that there was no fresh company-specific news behind the decline, instead pointing to profit-taking ahead of the September 2 quarterly results and doubts about the lower-margin custom AI-chip business. The drop also fits into a skepticism toward semiconductor stocks that has persisted since July.
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), an actively exploited security flaw (Broadcom), and continued layoffs (Oracle). In the coming weeks, two of the observed companies report next: Nvidia on August 26 and Broadcom on September 2.
