## Summary

Investors faced a volatile week as the Federal Reserve raised its benchmark rate by a quarter point to 3.75%‑4%, its first hike in three years. The move pushed the 10‑year Treasury yield back to 5% after it had briefly risen above 5.04% amid an oil price surge. The Dow fell 1.7%, marking a third straight losing week, while the S&P 500 slipped 0.08% and the Nasdaq gained 0.7%.

AI safety debates added pressure to tech stocks. Anthropic CEO Dario Amodei’s Sept. 12 essay calling for a slowdown of frontier model development sparked headlines, with OpenAI’s Sam Altman and SpaceX’s Elon Musk backing the call, while Nvidia’s Jensen Huang argued companies can self‑regulate. Chipmakers Intel and Micron each fell just over 5%, and data‑center firms GE Vernova and Eaton dropped about 9% and 8% respectively. Despite the sell‑off, Jim Cramer’s team added to Micron, saying they do not expect a meaningful slowdown in AI development or spending. CrowdStrike and Palo Alto Networks rose almost 15% and 10% as cybersecurity demand is expected to grow.

At Salesforce’s Dreamforce conference, the company forecast more than $63 billion in fiscal‑year‑2030 revenue and unveiled its AIforce interface and the Koa reasoning model built with Nvidia. The stock was described as “way too cheap” at roughly 15 times forward earnings, and Salesforce has bought back a cumulative $60 billion of stock.
