Top 10 Losers
- 🔴 DELL (Hardware / OEM) -8.90% — $536.02 — Giveback after last week's parabolic AI-server run (+16% on record $60.9B order backlog); profit-taking
- 🔴 ORCL (Big Tech / Platforms) -7.34% — $139.54 — Sent a force-majeure notice on a data-center project (sank ~5% Thu) atop debt load, negative FCF and rising bond yields
- 🔴 ADBE (Software) -5.44% — $238.93 — Continued slide on AI-disruption concerns to its SaaS franchise and soft forward guidance
- 🔴 BE (Industrial / Heavy Equipment) -5.03% — $266.65 — Giveback after last week's data-center power/hydrogen (Bloom) rally
- 🔴 NFLX (Consumer / Media) -4.77% — $71.72 — Consumer/media softness; streaming growth concerns
- 🔴 IBM (Software) -4.50% — $227.06 — Legacy-software giveback during the rotation into AI-capex
- 🔴 SPCX (Neocloud) -4.38% — $148.03 — Levered AI-infrastructure giveback; the overhang flagged on CRWV last week
- 🔴 SWKS (Mobile / Wireless) -3.84% — $87.81 — Post-Skyworks/Qorvo merger-clearance optimism faded after last week's gain
- 🔴 SPOT (Consumer / Media) -3.30% — $511.38 — Consumer/media weakness alongside NFLX
- 🔴 CSCO (Networking / Optical) -2.97% — $106.97 — Networking giveback as flows favored AI-capex semis/CPUs
Theme: A violent, FOMO-driven risk-on reversal — early-Monday CPU rally (INTC, ARM, AMD) sparked by Mideast de-escalation and Strait-of-Hormuz reopening hopes plus tumbling oil, then extended across the whole semi complex: accelerators (ALAB, CRDO), EDA (CDNS, SNPS), equipment (LRCX, AMAT, ONTO, KLAC, TER), memory (STX, MU) and AI-power (VICR, MPWR), with Meta's AI launches adding big-tech bid. Last week's leaders gave back (DELL, BE, SWKS), and the losers list is dominated by debt-financed AI-cloud (ORCL — force-majeure + negative FCF), disrupted SaaS (ADBE, IBM) and consumer/media. Net: capital rotated OUT of last week's power/server winners and INTO the AI-hardware/semi capex complex, punishing leverage and AI-disruption-exposed software along the way.
