IBM shares plunged -25.21% to close at $217.07 during regular trading, marking the worst single-day decline in the company's 115-year history — exceeding even the -23.7% drop on Black Monday in 1987. The rout was triggered by a preliminary Q2 earnings warning in which IBM guided revenue to ~$17.2 billion and adjusted EPS to $2.93, both missing consensus estimates, with CEO Arvind Krishna acknowledging the company "faltered" and failed to close numerous large deals.

WhiteFiber (WYFI) surged approximately 47% between mid-June and mid-July 2026, driven by a major AI compute contract, speculative call-option activity, and a Russell index reclassification that repositioned the stock in value-defensive benchmarks. Over the last quarter, the stock gained roughly 126%, reflecting sustained momentum from international expansion, strategic financing moves, and elevated investor appetite for AI infrastructure equities.

PRCT fell -9.05% during Tuesday's regular trading session, dropping from Monday's $21.22 close to approximately $19.30, with an intraday low of $18.88 marking a new 52-week low. The sell-off extended a prolonged downtrend — the stock is now down roughly -63% over the past year — with no single new catalyst; rather, accumulated competitive and reimbursement headwinds continued to weigh on sentiment.

FBYD shares plunged -15.23% during regular trading on Tuesday, falling to $11.08 from the prior session's close of $13.07, extending a brutal seven-day losing streak that has now erased roughly 41% of the stock's value since July 7. The selloff lacks a single company-specific catalyst, with the move driven primarily by technical breakdown and sentiment as the stock sliced through multiple support levels, including its 50-day moving average near $15.08 and the psychologically important $13.00 floor.

DNLI shares plunged -15.03% during regular trading on Tuesday, falling from a previous close of $26.48 to approximately $22.50 by midday, wiping out recent gains. The sell-off follows the Alzheimer's Association International Conference (AAIC) in London where CEO Ryan Watts delivered the opening plenary on July 12, triggering a classic sell-the-news reaction after the stock surged +82% over the past year into the event.

FAST shares have remained within a tight range over the past 30 days, reflecting investor caution ahead of the Q2 2026 earnings report scheduled for July 14.

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.

FCEL surged +17.4% during Monday's regular session, building on a +9% pre-market spike after UBS upgraded the stock from Neutral to Buy and raised its price target to $27 from $22. The UBS upgrade highlighted the FIT Energy data center agreement covering up to 380 MW, the Siemens collaboration for scalable fuel cell deployments, and FCEL's positioning as competitors focus on larger orders.

Oklo Inc. (OKLO) shares have fallen approximately 20.3% over the last 30 days, closing at $45.81 on July 13, 2026, down from $57.49 on June 12, 2026. The stock has declined roughly 27.7% over the broader quarter, reflecting waning enthusiasm for pre-revenue advanced nuclear energy names tied to AI infrastructure demand.

Gartner shares closed at $141.31 on July 13, 2026, reflecting a modest 4.6% decline over the trailing 30 days and a significantly steeper 46% year-to-date drop. The company's Q1 2026 earnings surpassed EPS estimates ($3.32 vs. $2.99 consensus), yet revenue of $1.49 billion missed expectations and contracted 1.5% year-over-year.

Applied Digital shares have fallen approximately 32% over the past 30 days, declining from $42.70 on June 12 to $28.84 as of July 13, 2026, underperforming the broader market. The selloff has been driven by escalating concerns over the company's aggressive debt-fueled expansion, customer concentration risk tied to CoreWeave, and persistent GAAP net losses despite robust revenue growth.

MP Materials shares declined approximately 14% over the past 30 days, falling from $57.55 on June 12 to $49.50 as of July 13, 2026. China's decision to add MP Materials to its export-control blacklist in late June triggered a sharp selloff despite the company's limited direct exposure to Chinese supply chains.

PayPay Corporation (PAYP) shares have rebounded approximately 7.8% over the last 30 days to $15.26, recovering from a steep sell-off that drove the stock to its 52-week low of $12.07 in mid-June. The broader quarterly trend remains negative, with the stock down roughly 21% from levels near $19.27 seen in early May, reflecting pronounced post-IPO volatility since the company's March 2026 Nasdaq debut.

Applied Optoelectronics (AAOI) shares dropped approximately 33.8% over the last 30 days, falling from $169.05 on June 12 to $111.88 on July 13, 2026. A wave of insider selling in mid-June, including transactions by the CEO and CFO, weighed heavily on investor sentiment.

Palantir shares are down approximately -5.00% in premarket trading, pulling back from Monday's close near $130.72 to roughly $124. The move appears tied to renewed valuation concerns and profit-taking following the stock's sharp rebound earlier this month, rather than a single company-specific catalyst.

IBM shares are down approximately -22.00% in premarket trading, one of the steepest single-session declines in the company's modern history. The primary catalyst is a preliminary second-quarter earnings disclosure that came in well below Wall Street's expectations, particularly in software and consulting revenue.

Five Below shares have edged approximately 3.5% lower over the past 30 days, trading near $191 after a volatile post-earnings period that saw the stock shed roughly 13% in a single session.

Hut 8 Corp (HUT) shares fell approximately 16.6% over the last 30 days, dropping from $118.86 on June 12 to $99.17 at the July 13 close, driven by a broader cryptocurrency and risk-asset selloff. Despite the 30-day decline, HUT remains up roughly 38% over the last quarter and has gained approximately 116% year-to-date, reflecting strong underlying momentum tied to its AI data center expansion.
