NVTS shares closed near $11.73, roughly 2% higher over the trailing 30 days but still down approximately 35% from the end of June. Navitas is executing its "Navitas 2.0" pivot away from mobile and consumer markets toward GaN and high-voltage silicon carbide (SiC) for AI data centers and grid infrastructure.

NVDA gained +2.73% to about $231.21 during regular trading, versus Friday's close of $225.07. The move was driven by the board approving a $150 billion buyback increase, lifting total authorization to a record $235 billion.

Credo Technology is a stock, not an ETF, and the widely discussed target is $300 per share — a level roughly 45% above recent trading near $205. Fiscal 2026 revenue more than tripled to roughly $1.34 billion, and management has guided to over 80% revenue growth for fiscal 2027.

CRDO fell -8.52% to about $193.00 during regular trading, down from its prior close of $210.97. The primary catalyst was newly disclosed insider selling: the CTO sold 27,500 shares and another insider sold 5,000 shares under pre-arranged 10b5-1 plans, roughly $6.2 million combined.

Optical inflection ahead: Management expects fiscal 2027 optical revenue to exceed $600 million, with ZeroFlap optics, silicon photonics, and optical digital signal processors (DSPs) each contributing more than $100 million. Accelerating guidance: The company has raised its fiscal 2027 revenue growth outlook to roughly 85% year over year, signaling confidence in second-half ramps across new products.

QCOM fell -5.69% during Monday's regular session, dropping from $201.97 to roughly $190.47. The primary catalyst was soft fiscal Q4 guidance — adjusted EPS of $2.05–$2.25 versus a $2.36 consensus — released with quarterly results, pressuring the stock into today's session.

ARM is down -7.99% to $285.54 in regular trading, after closing Friday at $310.32. The drop began premarket (down roughly -4%) and widened through the early session as chip stocks sold off broadly.

Arm's first production chip is the defining catalyst. The Arm AGI CPU — the company's initial data-center silicon, purpose-built for agentic artificial intelligence (AI) — has accumulated more than $2 billion of customer demand for fiscal 2027 and 2028, more than double the level disclosed at launch. Strategic positioning is strengthening. Arm-based compute now represents roughly 50% of central processing unit (CPU) share among top hyperscalers, supported by wins at Amazon Web Services, Google Cloud, Microsoft, and NVIDIA.

Astera Labs (ALAB) shares climbed about +25.6% over the trailing 30 days, rebounding from a late-August close near $290 to finish at $364.62 on Sept. 25, 2026. The advance was driven by renewed AI data-center momentum, the expansion of the Leo Smart Memory Controller lineup, and updates on the Scorpio X fabric switch production ramp.

Qualcomm (QCOM) shares climbed roughly 23% over the last 30 days, rising from about $164.19 to $201.97. The September 8 partnership with Amazon (AMZN) to co-develop custom AI data-center chips was the principal catalyst.

Arm Holdings (ARM) gained roughly 23.6% over the last 30 days, rising from a close near $251.06 to about $310.32. The surge was driven by rising AI-driven CPU demand after Meta Platforms unveiled its Muse AI agent and reports indicated a joint custom-processor effort with Arm.

Different semiconductor models: Ceva licenses intellectual property (IP) for wireless connectivity and edge AI, while MaxLinear sells physical radio-frequency and optical data-center chips. Scale gap: MaxLinear's roughly $7.7 billion market capitalization is more than eight times Ceva's, though both remain unprofitable on a GAAP (Generally Accepted Accounting Principles) basis.

MXL is up +11.55% during the regular session, trading near $95.16 versus a prior close of $85.31. The rally was driven by Q3 results that beat revenue expectations, paired with an upbeat Q4 outlook.

Advanced Micro Devices shares climbed roughly 30.8% over the trailing 30 days, from a close of $480.93 on August 26 to $629.26 on September 24, 2026. The advance pushed AMD's market capitalization above $1 trillion for the first time, making it the fourth U.S. chipmaker to cross that milestone.

Marvell Technology (MRVL) rose roughly 5.7% over the trailing 30 days, from about $245.11 to $258.95, a move well below the 10% threshold that would signal a sharp directional swing. Fiscal second-quarter results set records — revenue of $2.74 billion, up 37% year over year, with adjusted EPS of $0.94 — but shares initially fell on a thin beat and lower near-term margin guidance.

Nebius Group (NBIS) operates as an AI-focused infrastructure and cloud provider with a strategic alliance to NVIDIA Corporation, positioning it as a complementary player in the AI ecosystem. NVIDIA (NVDA) maintains leadership in graphics processing units (GPUs) and artificial intelligence accelerators, driving broader market influence through its hardware dominance and software ecosystem.

MU and SNDK both operate in the memory and storage semiconductor space, benefiting from AI-driven demand for high-performance chips. MU has delivered exceptional year-to-date returns exceeding 278% amid strong earnings growth and analyst optimism.

Arm Holdings (ARM) closed at $264.79 on September 11, 2026, up 4.17% on the day, but down roughly 2.6% over the trailing 30 days from $271.87. Shares remain sharply higher year to date at about 139%, though they trade well below the 52-week high of $452.70.

AMD shares climbed roughly 30% over the trailing 30 days, from a close near $473 to about $615, pushing the company's market value above $1 trillion for the first time. The rally was powered by surging AI-driven demand for data-center CPUs and GPUs, led by the EPYC server line and the Instinct MI400 and Helios accelerators.

Intel shares climbed roughly 35% over the 30-day period ending in late September 2026, rising from a closing price near $90 to about $121.78. The advance was fueled by renewed AI-server CPU demand, a reported SK Hynix manufacturing partnership, and a wave of Wall Street upgrades.
