## Summary

The Nasdaq rose 2.3% over the period, while the Dow fell nearly 1%. Cybersecurity stocks like **CrowdStrike** surged 19.4% as concerns about AI risks spiked demand for network protection. **Anthropic**’s CEO, Dario Amodei, amplified the trend with an essay urging slower AI development for safety reasons. **Meta Platforms** climbed 14.4% after its AI agent **Muse** and its upgraded **Muse Wonder Full** gained traction, with Wells Fargo calling the latter a frontier model. Retailer **TJX Companies** rebounded 13% following August earnings concerns, though Q2 weakness stemmed from consumer spending pullback, according to Morgan Stanley.

**FedEx Freight** dropped 12.4% amid rising diesel prices from the Iran war, while **Boeing** fell 9.8% over fuel costs, aerospace industry anxiety, and a software issue delaying 737 Max 10 certification. The Federal Aviation Administration later ruled the software glitch posed no flight-safety risk. The analysis reflects broader market divisions between tech and non-tech sectors, with AI and cybersecurity driving gains while financials and industrials faced headwinds.

## Key points

- CrowdStrike rose 19.4% as AI safety fears boosted cybersecurity demand, with Anthropic’s CEO Dario Amodei’s essay cited as a catalyst
- Meta Platforms gained 14.4% after launching Muse Wonder Full, which Wells Fargo ranked as a frontier AI model

## Why it matters

The shifts highlight how AI-driven sectors like cybersecurity and tech outperform amid economic uncertainty, while traditional financials and industrials lag. Investors are weighing AI’s long-term growth potential against near-term borrowing risks.
