Technology stocks face volatility amid AI development concerns

The technology and semiconductor sectors have experienced significant volatility driven by shifting sentiment regarding artificial intelligence. On September 14, chipmaker stocks saw a sharp sell-off following remarks from executives at Anthropic, OpenAI, and xAI, who advocated for caution in the pace of frontier model development. This led to declines in NVIDIA, AMD, Broadcom, and Intel, with the PHLX semiconductor index dropping approximately 5.9% in a single session.

Despite these fluctuations, some individual companies have shown strength. AMD stock rose after analysts reiterated an overweight rating, citing demand for CPUs and GPUs that continues to exceed supply. Similarly, Apple reported strong fiscal third-quarter results, with revenue reaching $109.4 billion, driven by significant growth in both iPhone and Services divisions. Analysts also noted potential demand for a future foldable iPhone Duo.

In the broader market, the NASDAQ 100 remained relatively stable, closing nearly unchanged. While concerns about an AI slowdown persist, some analysts suggest that a slower pace of model iteration could extend the utility of existing hardware, potentially stabilizing long-term demand for chipmakers.
