[Deep Dive] Nasdaq Rebounds 1.3%: Led by AI and Semiconductor Stocks

Nasdaq Composite Rebounds Over 1% on Tech Strength

The Nasdaq Composite Index, which had recently experienced volatility due to profit-taking and geopolitical risks, has firmly returned to a strong upward trajectory. On July 9, 2026 (local time), the Nasdaq closed at 26,206.89, up 1.30% from the previous trading day. This index rebound was primarily driven by robust buying in AI and semiconductor-related technology stocks. Dispelling recent concerns about the profitability of the AI industry, investors are once again making strong bets on the medium- to long-term growth potential of tech equities.

Micron and Meta Ignite AI Investor Sentiment

The main driving force behind this rise in the Nasdaq Composite was the announcement of specific AI investment and chip production plans by major tech corporations, signaling continued aggressive capital expenditure.

• Micron Technology: Announced a massive plan to invest over $250 billion in U.S. manufacturing facilities by 2035 to preemptively meet the explosive global demand for AI memory. Bolstered by this news, its stock surged more than 4.5%, leading the broader market sentiment.

Meta Platforms: Formalized its plans to produce its own AI chips to strengthen its AI infrastructure independence. This strategic move aims to reduce reliance on external providers and increase efficiency, raising investor expectations and recording a gain in the 4% range.

Furthermore, the Philadelphia Semiconductor Index surged more than 3% in tandem, supporting the overall strength of the semiconductor sector. The fact that the book-building for SK Hynix's American Depositary Receipts (ADR) attracted subscriptions exceeding seven times the offering volume is another clear testament to the robust investor sentiment in the global AI semiconductor market.

Outlook: Impact of the Q2 Earnings Season

Current market participants are placing more weight on the actual fundamentals and growth potential of companies rather than short-term geopolitical tensions or macroeconomic issues. In the upcoming Q2 earnings season, how well big tech companies prove their AI sector achievements with concrete and visible figures will be paramount. If additional growth momentum is confirmed through earnings guidance, the upward trend of the Nasdaq Composite Index is expected to continue smoothly into the second half of the year.
