Notable Catalysts

MRVL -- Earnings After Close Today: Marvell Technology reports Q1 FY2027 results after the bell. The stock is already down 4.6% ahead of the print, suggesting hedging or position trimming. Custom silicon momentum and data center revenue guidance will be the key metrics. Post-earnings move could cascade across CLS, CRDO, and COHR (optical/connectivity names).

QCOM -- Sharp Selloff (-6.2%): Qualcomm seeing heaviest selling across the entire tracker. Edge AI/mobile segment showing weakness as broader semi rotation favors memory and foundry over mobile exposure. Keep an eye on whether this becomes a multi-day rerating.

MU -- Memory Rally (+3.6%): Micron surging on continued HBM demand optimism. WDC rising in sympathy (+1.1%). Memory/storage is the strongest sector today as AI training workloads keep pushing DRAM/HBM pricing power.

TSM -- Foundry Strength (+2.5%): TSMC climbing as AI chip demand narrative remains intact despite broader semi weakness. The foundry/memory trade continues to outperform equipment and EDA names.

CRWV -- Insider Selling Overhang: CoreWeave down another 1.5% at $104.27. Heavy insider selling (CEO Intrator $19.7M, CFO $1M) and DA Davidson downgrade to Neutral (PT $100) continue weighing on sentiment. Confirmed stay-away.

Entry Zone Alerts

META to Semi Rotation -- Current Levels

Tracking against the $300K META rotation plan targets. META surged to ~$630 today, expanding the capital base if not yet sold. MRVL earnings event risk (the planned gate before execution) resolves after close today.
