STM plunged -16.92% during regular U.S. market hours after issuing Q3 revenue guidance of $3.70 billion, roughly 2% below the $3.76–$3.79 billion analyst consensus. The Q3 outlook miss overshadowed an otherwise strong Q2 report: revenue rose +26% YoY to $3.49 billion, non-GAAP EPS of $0.31 beat estimates by $0.06, and the company swung from a year-ago loss to a $222 million net profit.

Texas Instruments reported Q2 2026 revenue of $5.46 billion, up 23% year over year. Diluted earnings per share reached $2.14, exceeding analyst estimates and rising 52% from the prior year.

MACOM Technology Solutions (MTSI) shares fell approximately 28.6% over the last 30 days, dropping from $396.26 on June 22 to $283.03 by July 21, 2026. Removal from major Russell value benchmarks — including the Russell 1000 Value and Russell Midcap Value indexes — triggered forced institutional selling and amplified downside momentum.

GlobalFoundries shares plummeted approximately 33.8% over the last 30 days, sliding from $89.67 on June 22 to $59.39 as of July 21, 2026. The sell-off erased roughly $17 billion in market capitalization and included seven consecutive losing sessions in mid-July alone.

Texas Instruments is scheduled to report second quarter 2026 results after market close on July 22, with the earnings conference call set for 3:30 p.m. Central time. Analysts expect earnings per share of $1.91 for the quarter, according to consensus estimates.

ON Semiconductor shares fell roughly 30.8% over the past 30 days, driven overwhelmingly by the announcement of a $7 billion all-stock acquisition of Synaptics ( SYNA ) on June 25, 2026. The deal triggered the stock's worst single-day decline since 2020, with ON plunging approximately 19.6% on June 26 as investors priced in immediate shareholder dilution and execution risk.

NVIDIA shares have pulled back approximately 3.7% over the past 30 days, reflecting broader tech-sector consolidation and profit-taking after a sustained rally. The company remains the dominant force in AI accelerator chips, with its data-center segment continuing to drive outsized revenue growth.

Analog Devices (ADI) has delivered stronger year-to-date returns compared to Microchip Technology (MCHP), supported by robust AI-driven demand in analog semiconductors. Both companies operate in the semiconductor sector but differ in focus: ADI emphasizes high-performance analog and mixed-signal solutions, while MCHP specializes in microcontrollers and embedded systems with growing data center exposure.

ADI currently trades near $375 after pulling back from a 52-week high of $445.91, placing the $500 target roughly 33% above recent levels. The strongest bullish catalysts include surging AI-driven data center demand, where revenue grew approximately 90% year-over-year, and a broad recovery across industrial and automotive end markets.

Analog Devices (ADI) shares declined approximately 13.6% over the last 30 days, falling from $434.46 to $375.36 amid broad-based selling pressure in semiconductor stocks. The pullback erased gains from a powerful rally that pushed ADI to a 52-week high of $445.91 in late June, leaving the stock roughly flat on a quarterly basis.

Marvell Technology shares have dropped approximately 39% over the past 30 days, falling from $310.58 on June 18 to $188.68 on July 17, as a broad semiconductor selloff erased a substantial portion of 2026's gains. The decline was triggered by multiple headwinds: AI capex spending fears, stretched valuations exceeding 80x earnings, insider selling by top executives, and a hawkish Federal Reserve repricing.

Arm Holdings shares dropped approximately 39% over the last 30 days, sliding from around $439 on June 18 to $267 on July 17, as a convergence of analyst downgrades, valuation concerns, and AI-sector rotation triggered sharp selling pressure. Over the broader quarter, the stock remains up roughly 60% despite the recent pullback, reflecting the powerful rally that preceded the June peak above $452 before the selloff began.

Qualcomm shares fell approximately 24% over the last 30 days, dropping from $226.11 on June 18 to $171.78 as of July 17, 2026. The stock's decline was triggered by a "sell-the-news" reaction to Qualcomm's June 24 Investor Day, where ambitious data center and AI diversification targets through fiscal 2029 failed to offset near-term concerns.

Intel (INTC) shares dropped approximately 29% over the past 30 days, sliding from around $134 to roughly $95, erasing a significant portion of gains from the stock's massive first-half rally. The selloff was triggered by a broad semiconductor sector rotation, amplified by company-specific concerns around 18A process node yield timelines and Intel's eroding competitive position in the data center market.

Micron Technology shares fell approximately -25% over the last 30 days, dropping from $1,133.99 on June 18 to $848.95 on July 17, 2026, erasing a significant portion of the stock's massive year-to-date gains. The selloff was driven by a combination of profit-taking after the June 25 all-time high of $1,255, a broad semiconductor sector rotation, and mounting concerns about the memory cycle peaking.

Second quarter revenue reached US$40.20 billion, up 36.0% year-over-year and 12.0% sequentially, at the high end of guidance. Diluted EPS came in at US$4.31, a 77.4% increase year-over-year, exceeding analyst estimates.

MXL plunged -14.53% intraday on Thursday, falling from Wednesday's close of $88.84 to $75.93 during regular trading hours, accelerating a multi-day selloff. The drop follows Wednesday's -4.05% decline and premarket weakness, reflecting heavy profit-taking after the stock's extraordinary +406% year-to-date rally left valuations stretched at 11.4x forward sales.

Micron shares plunged -9.50% during regular trading Wednesday, dropping from a prior close of $983.12 to approximately $889.68 intraday, as a broad semiconductor selloff swept through the memory sector. The selloff was triggered by renewed concerns over memory chip pricing and looming oversupply after SK Hynix's Nasdaq listing, where it raised $26.5 billion to fund plans to double DRAM production by 2030.

Silicon Motion Technology (SIMO) shares gained approximately 9.2% over the last 30 days, supported by surging AI-driven enterprise storage demand and a series of dramatic analyst price target increases. Morgan Stanley raised its SIMO price target from $155 to $400 in early July, while Wedbush lifted its target to $400 and Bank of America set a Street-high $450, all citing the accelerating NAND cycle tied to AI data center buildouts.

TSEM surged +12.14% to $257.57 during Tuesday's regular session, following an even stronger premarket pop of nearly +19% after the company unveiled a transformative $3 billion expansion plan in Japan. The primary catalyst: Tower Semiconductor announced a dual-track manufacturing expansion in Japan focused on 300mm silicon photonics and silicon germanium production, backed by approximately $1 billion in Japanese government grants.
