ICHR tumbled -13.91% during Monday's regular trading session, falling to $74.51 from Friday's close of $86.55, making it one of the steepest decliners on the Nasdaq. The selloff was driven by a broad semiconductor sector rout, with the group down roughly -3.3%, as names like MaxLinear also fell sharply alongside Ichor.

Applied Materials shares declined approximately 19.7% between June 25 and July 24, 2026, falling from $668.00 to $536.25 as a sector-wide semiconductor sell-off took hold. The stock remains up roughly 28.6% over the trailing quarter despite the recent pullback, reflecting the powerful AI-driven rally that propelled AMAT to an all-time high of $739.67 on June 30.

KLA Corporation (KLAC) shares declined approximately 18.7% over the past 30 days, falling from $258.80 on June 25 to $210.52 on July 24. The stock hit an all-time high of $301.71 on June 30 before a sharp reversal triggered by insider selling, valuation concerns, and broad semiconductor sector rotation.

AEHR tumbled -12.04% during regular trading on Friday, extending a multi-session slide from its post-earnings peak of $98.91 on July 21 to approximately $77.85. The selloff reflects aggressive profit-taking after the stock surged over +40% following its July 14 blowout fiscal Q4 earnings report and FY2027 revenue guidance of $130M–$150M, implying 160%–200% year-over-year growth.

Applied Materials (AMAT) and KLA Corporation (KLAC) both supply critical equipment to the semiconductor industry, with AMAT focusing on deposition and etch processes while KLAC specializes in process control and yield management. In recent market activity, both stocks have delivered strong year-to-date gains amid AI-driven demand for advanced chips, though the sector has experienced periodic volatility.

Both AMAT and LRCX operate in the semiconductor equipment sector and have delivered substantial year-to-date gains amid strong demand for AI-related chip manufacturing tools. Recent market activity has seen heightened volatility across the sector, with AMAT experiencing notable intraday and weekly declines while LRCX has retreated from earlier all-time highs.

Price target in focus: $800 per share represents a roughly 51% upside from the July 17 closing price of $529.66 and sits above the stock's all-time high of approximately $740. Strongest bullish factors: Unprecedented wafer fabrication equipment (WFE) spending driven by AI chip demand, multi-year order visibility stretching toward 2030, and record revenue and margin performance.

Applied Materials (AMAT) shares declined approximately 14% over the last 30 days, falling from $617.11 on June 18 to $529.66 by July 17, 2026. The drop was driven by a broad semiconductor sector selloff, renewed U.S.-China export control concerns, and substantial insider selling by top executives including CEO Gary Dickerson.

Teradyne shares dropped approximately 26% over the last 30 days, falling from $437.92 (June 18 close) to $322.36 (July 17 close), as a broader semiconductor equipment selloff intensified. The decline was primarily driven by sector-wide pressure after TSMC's capital expenditure reset and ASML's cautious commentary sparked multiple compression across chip-equipment names.

The $300 price target represents approximately 37% upside from KLAC's recent price of roughly $219 and sits above the consensus analyst target of $234 but within the range of the most optimistic Wall Street forecasts. AI-driven semiconductor demand is the strongest bullish catalyst, with wafer fab equipment (WFE) spending projected to reach $145–150 billion in 2026 and potentially $250 billion by 2028.

KLAC shares closed at $219.37, down -2.29% (-$5.13) during the regular trading session, extending a volatile stretch for the semiconductor equipment maker. The decline came despite Oppenheimer raising its price target to $260 from $200 and reiterating an Outperform rating, citing AI-driven supply constraints and accelerating capacity plans.

AXTI dropped -14.51% during regular trading, falling from a prior close of $53.42 to approximately $45.67 on elevated intraday volume. A broad semiconductor sector sell-off dragged the group down roughly -4.7%, with AXTI leading decliners as the weakest name in the sector.

ASML reported Q2 2026 total net sales of €9.3 billion, exceeding guidance and consensus expectations. Gross margin reached 54.0%, above the guided range, supported by strong installed base performance.

Aehr Test Systems reported fiscal 2026 fourth-quarter revenue of $18.8 million, up from $14.1 million in the prior-year period. GAAP net income reached $1.4 million, or $0.04 per diluted share, compared to a net loss of $2.9 million, or $0.10 per diluted share, a year earlier.

Ichor Holdings shares traded at $90.41 as of July 13, 2026, gaining approximately 4% over the prior 30 days amid continued semiconductor equipment demand momentum. First quarter 2026 revenue reached $256.1 million, exceeding analyst expectations, while non-GAAP EPS of $0.15 beat the consensus estimate of $0.13.

Aehr Test Systems is scheduled to report fiscal 2026 fourth quarter and full year results on July 14, 2026, after market close. Analysts expect the company to deliver revenue on the high end of its $45 million to $50 million full-year guidance range.

AXT, Inc. (AXTI) shares have plunged approximately 50% over the past 30 days, falling from $97.18 on June 12 to $48.55 as of mid-July 2026, marking one of the sharpest corrections in the semiconductor substrate sector. The selloff represents a dramatic momentum unwind after the stock surged from roughly $2 in early 2025 to an all-time high of $143.16 in late May 2026, driven by AI-fueled demand for indium phosphide (InP) wafers.

AXTI plunged -15.57% during Monday's regular trading session, extending a brutal multi-week selloff that has now erased roughly 58% of the stock's value since its mid-June peak near $116. The decline is driven primarily by a broad-based semiconductor and AI-sector risk-off rotation, with smaller-cap, high-beta names like AXTI bearing the brunt of liquidity withdrawal as traders de-risk speculative positions.

Applied Materials (AMAT) provides semiconductor manufacturing equipment with steady demand tied to advanced chip production, showing resilience amid sector volatility. Intel (INTC) focuses on chip design and manufacturing, experiencing sharper price swings driven by AI-related catalysts and competitive positioning in data centers.

Price target in focus: $100 per share — the high end of Wall Street analyst price targets and a psychological round-number milestone for Amkor Technology. AI and advanced packaging momentum: Rapidly growing demand for 2.5D packaging, AI accelerator chips, and high-performance computing represents the strongest bullish catalyst.
