Stock Market News — October 02, 2026 — Morning Update — Last 12 Hours (Pacific Time)

Markets surged Friday as a softer jobs report cooled Fed rate hike expectations, while Nvidia hit record highs and Arm jumped 7% on AI momentum. However, Seagate and Western Digital plummeted over 12% on Toshiba's HDD expansion plans, and Nike tumbled 10% on disappointing guidance.

Executive Summary

Markets are broadly higher on Friday after a softer-than-expected U.S. jobs report cooled Fed rate hike bets, lifting equities and easing Treasury yields. The AI trade remains the dominant bullish force — Nvidia hit a record high, Arm surged 7%, and a cascade of analyst upgrades swept through the semiconductor and tech space. The session's biggest shock came from the HDD storage sector, where a Nikkei report on Toshiba's planned capacity expansion sent Seagate and Western Digital into double-digit freefall.


Sentiment Breakdown

Sentiment Count Percentage
🟢 Bullish 128 58%
🟡 Neutral 41 18%
🔴 Bearish 53 24%

Net Sentiment: Moderately Bullish — Broad equity gains across the U.S. and Europe, AI optimism, and strong delivery numbers from Tesla and Rivian outweigh localized pain in HDD stocks, Nike, and bond markets.

Market Implications

The softer payrolls print is the macro gift markets needed — it gives the Fed cover to pause, takes pressure off long-duration assets, and provides a fundamental justification for the AI-driven equity rally to continue. However, Citi's warning that bond volatility without Fed repricing is "concerning" is worth watching: if yields resume their climb next week without a clear catalyst for rate cuts, the equity relief rally could prove short-lived. Standard Chartered's new call for an ECB rate hike in December adds another layer of complexity for European assets.

The HDD sector blowup is a reminder of how quickly competitive dynamics can reprice an entire industry. Seagate and Western Digital losing double-digit percentages in a single session on a Nikkei report — even as analysts questioned whether Toshiba's expansion would actually ease supply — illustrates the hair-trigger sensitivity of concentrated sector bets. Investors in storage names should watch for any Toshiba confirmation or denial next week.

The AI capital cycle is entering a new phase of scale. Broadcom assembling $60 billion for Anthropic chips, Amazon offloading $8 billion of Nvidia chips via a new investment vehicle, and SoftBank completing its $30 billion OpenAI commitment all in the same session signals that the infrastructure financing architecture around AI is becoming as complex — and potentially as risky — as the technology itself. The Anthropic IPO prospectus warning on government relationship risk is a timely flag for investors pricing in a smooth path to monetization.
