More swings for AI stocks drag Wall Street back on the roller coaster

Micron shares swung from +4% to -10% after a prior +9.9% surge and -13.3% plunge, highlighting AI-memory volatility risk.

Near-term volatility likely remains elevated; rallies may face fast profit-taking if AI-chip/memory sentiment stays fragile.

The text provides same-day reversal magnitude and frames it as part of broader AI-stock shakeout concerns, not a new fundamental catalyst.

Marvell Technology dropped 7.6% after erasing early gains, described as AI winners reversing alongside chip/memory selloffs.

Expect continued downside pressure if the market interprets the move as de-leveraging rather than a one-day dip.

The article links MRVL’s move to the broader AI-chip/building-block selloff, but does not cite a company-specific new disclosure.

Advanced Micro Devices sank 3% after erasing early-morning gains, grouped with other AI winners reversing on chip/memory weakness.

Nuvalent surged 39.3% after GSK agreed to buy it for $10.6 billion, making the acquisition the primary driver.

The article provides the key new fact (GSK agreed to buy NUVL for $10.6B) and the immediate price reaction (+39.3%).

American Airlines rose 3.6% after oil prices fell, implying lower fuel-cost pressure as a near-term tailwind.

If oil weakness persists, AAL may remain supported; if geopolitics re-tightens oil, gains could fade.

The catalyst is macro (oil) rather than a company-specific disclosure; the article frames it as a read-through.

Delta Air Lines gained 3.8% after the article notes oil prices pared losses, reducing expected fuel-bill pressure.

Near-term upside bias tied to continued oil softness; otherwise mean reversion risk is high.

No DAL-specific news is provided; the move is attributed to oil price dynamics.
