LongbridgeAII'm LongbridgeAI, I can summarize articles.

The Fed raised rates by 25bps to 3.75%-4%. Semiconductor stocks surged with Nvidia up over 2% and Intel jumping over 8%, while Moderna soared over 10%.

On September 17, U.S. stocks traded mixed after the Federal Reserve's rate decision. As of writing, markets were digesting the Fed's 25-basis-point rate hike to 3.75%-4%, with the Fed Chair striking a decisively hawkish tone and the dot plot signaling one more potential hike this year. Tech stocks showed relative strength.

Across the tape, the semiconductor sector rallied across the board, with Nvidia rising over 2% to lead gains and Intel surging over 8% in a standout performance. In healthcare, Moderna jumped over 10% to top the sector. The EV space was also active, with Tesla advancing nearly 4%. Financials edged lower, with Bank of America posting a slight decline.

Semiconductor Sector Surges, Intel Jumps Over 8%

As of writing, Nvidia (NVDA) rose 2.44% to $219.11, leading the market in turnover; Intel (INTC) surged 8.06% to $109.20; Super Micro Computer (SMCI) gained 6.16% to $39.12.

On the news front, Nvidia CEO Jensen Huang projected that chip sales would double by 2027 and announced that the Vera Rubin NVL72 has entered full production, with shipments expected to begin by late 2026. The product achieved 3.7x the inference throughput of the GB300 in MLPerf testing. Additionally, analysts noted that Nvidia trades at a P/E of 27x, well below AMD's 131x and Broadcom's 46x, offering a relative valuation advantage among AI chip stocks.

Healthcare Stocks Diverge, Moderna Surges Over 10%

As of writing, Moderna (MRNA) jumped 10.86% to $161.43; Pfizer (PFE) edged up 0.76% to $27.67. On the flip side, PDS Biotechnology (PDSB) tumbled 16.07%.

EV Sector Active, Tesla Gains Nearly 4%

As of writing, Tesla (TSLA) climbed 3.91% to $372.09; Plug Power (PLUG) advanced 6.53% to $2.15; NIO (NIO) added 1.12% to $3.62.

In related news, Tesla's Cybercab is facing NHTSA regulatory scrutiny, while rival Waymo accelerates its global expansion. Still, the market's current focus remains on Tesla's long-term positioning in AI and autonomous driving.

Elsewhere, Apple (AAPL) inched up 0.26% to $333.28; Bank of America (BAC) slipped 0.32% to $57.72. Notably, a CICC research note characterized the rate hike as a neutral outcome, arguing that AI investment and reflexive dynamics limit the scope for aggressive consecutive hikes. Should AI catalysts persist, the note suggested further upside for U.S. equities remains in play.
