SRAD fell -19.53% during Monday's regular session after reporting Q2 2026 results before the open that missed across both top and bottom lines. The company posted an adjusted loss of -$0.01 per share, widely missing the consensus estimate of +$0.07, with revenue of $431.2M also coming in below the $436M consensus.

WDC fell −5.31% during Monday's regular trading session, dropping from Friday's close of $544.84 to approximately $515.90 as the broader memory and storage sector sold off sharply. The decline is part of a sector-wide rout: Micron fell −3.44%, SK Hynix −3.62%, SanDisk −3.89%, and Seagate −3.35%, with the Philadelphia Semiconductor Index coming off its worst month since 2008 in July.

STX tumbled -7.70% during Monday's regular session, sliding from Friday's close of $856.13 to $790.17, as a cascading selloff in South Korean chipmakers triggered contagion across global storage and memory stocks. The primary catalyst was a -5% plunge in South Korea's KOSPI, where Samsung and SK Hynix each fell roughly -9%, extending a brutal July that saw the index lose -22% — its worst month since the 2008 financial crisis — amid forced deleveraging of single-stock leveraged ETFs tied to chip names.

ARM is trading at $222.71 during the regular session, down -7.08% from Friday's close of $239.69, as post-earnings selling intensifies into a second week. The sell-off extends the stock's decline following its July 29 Q1 FY2027 report, where in-line revenue of $1.29B (+22% YoY) and unchanged AGI CPU demand guidance failed to justify the stock's ~245x P/E multiple.

SpaceX (SPCX) shares have declined approximately 34% over the past 30 days, falling from $162.00 on July 2 to around $106.33 as of early August, and are now trading well below the June IPO price of $135. The stock's all-time high of $225.64, reached on June 16, has given way to a sustained sell-off that has erased over $1 trillion in market capitalization from peak levels.

Tesla shares dropped approximately 21% over the past 30 days, slumping from around $393 to near $313, driven primarily by a sharply disappointing Q2 2026 earnings report. The sell-off was triggered by a massive earnings miss — adjusted EPS of $0.33 versus analyst estimates of $0.51 — alongside negative free cash flow for the first time in two years.

MU is down -5.83% during Monday's regular session, extending pre-market weakness of roughly -2%, with shares sliding from Friday's close of $823.03 to approximately $775. The primary catalyst is China's CXMT announcing plans to build a second DRAM plant in Beijing, which could more than double its production capacity and threaten the pricing power of incumbent memory makers.

Micron Technology (MU) shares declined approximately 20.8% over the last 30 days, falling from $975.56 on July 2 to $772.87 as of August 3, 2026. The sell-off erased over $400 billion in market value despite Micron reporting the strongest quarterly results in company history, with fiscal Q3 revenue of $41.46 billion — up 346% year over year.

Intel shares fell approximately 28% over the last 30 days, erasing a significant portion of the stock's massive first-half 2026 rally. Reports that the 18A manufacturing process may not reach profitable yields until late 2026 or 2027 triggered the sharpest selling, undercutting the core turnaround narrative.

Applied Materials (AMAT) shares fell approximately 17.4% over the last 30 days, sliding from $603.04 on July 2 to $497.99 by early August 2026. The decline is part of a broader correction: AMAT plunged roughly 41% from its 52-week high of $739.67 set on June 30 before staging a 15% single-day rebound on July 30.

Caterpillar shares have fallen approximately 16% over the past 30 days, dropping from around $964 to roughly $810, as a confluence of bearish catalysts triggered a sharp correction from record highs near $1,065. High-profile investor Michael Burry disclosed a short position at $1,060.98 in late June, arguing that CAT's price-to-sales ratio had reached a three-decade high and its valuation was unsupported by underlying business fundamentals.

Lam Research (LRCX) shares have fallen approximately 20.4% over the past 30 days, dropping from $351.41 on July 2 to $279.66 as of August 3, 2026. A broader semiconductor equipment sector selloff, profit-taking after a massive year-to-date rally, and mounting valuation concerns have driven the steep decline.

ARM shares surged approximately 16.8% over the past 30 days, driven by strong AI-related demand and upbeat market sentiment around semiconductor licensing. Over the last quarter, ARM has maintained a robust upward trajectory, reinforcing its position as a key beneficiary of the ongoing artificial intelligence infrastructure buildout.

KLA Corporation (KLAC) shares have fallen approximately 25% over the past 30 days, plunging from $235.55 on July 2 to $176.30 as of early August 2026. The decline is part of a broader semiconductor sector rotation, with the stock down roughly 42% from its June 30 all-time high of $301.71.

IBM stock has fallen approximately 22% over the last 30 days, driven primarily by a historic single-day collapse of 25.2% on July 14 following a surprise preliminary Q2 earnings warning. The selloff was the worst single-day decline in IBM's history as a public company, erasing roughly $70 billion in market value.

SanDisk Corporation (SNDK) shares fell approximately 46% over the last 30 days, retreating sharply from near all-time highs as profit-taking and macro concerns gripped the memory sector. The decline follows an extraordinary rally that saw the stock surge over 700% year-to-date through late June, fueled by surging AI-driven demand for NAND flash memory.

Marvell Technology shares dropped approximately 26.9% over the 30-day period ending August 3, 2026, falling from $245.29 to $179.32, driven primarily by a sector-wide semiconductor selloff rather than company-specific weakness. The stock's dramatic decline erased gains from a parabolic rally that saw MRVL peak at $329.88 on June 18, with the drawdown fueled by AI capex sustainability fears, stretched valuations, and profit-taking after S&P 500 inclusion.

AppLovin shares fell approximately 23% over the past 30 days, declining from $527.06 on July 2 to $405.03 as of early August 2026. A pivotal Bank of America research note flagged slowing e-commerce advertising pixel growth, triggering a single-day drop of roughly 12.6% on July 13.

Corning (GLW) fell roughly 32% over the past 30 days, extending a brutal July in which the stock posted its worst monthly performance in 24 years with a decline of approximately 46%. The sell-off was triggered by third-quarter guidance that came in slightly below elevated Wall Street consensus estimates, despite second-quarter results beating on both revenue and earnings per share.

Vertiv (VRT) shares tumbled approximately 20.5% over the last 30 days, driven primarily by a sharp post-earnings selloff on July 29 following a Q2 revenue miss. The company beat adjusted EPS estimates ($1.52 vs. $1.43 consensus) and raised full-year 2026 guidance, yet investor focus locked onto the $110 million revenue shortfall and supply-chain execution concerns.
