Entry Zone Alerts — Semi Rotation Plan
Tracking against the planned ~$300K META → semi supply chain rotation (NVDA 30%, TSM 25%, ASML 20%, AMAT 10%, AVGO 10%).
NVDA $219.51 — Day 2 of post-earnings sell-the-news. Drifting below the $223 post-earnings range. If the rotation is happening, this dip into $217–220 is a zone worth watching for the 30% ($90K) allocation.
AVGO $414.57 — Pulling back -0.76% while peers rally. Relative weakness could set up a better entry for the 10% ($30K) tranche vs. the $425 level it touched last week.
AMAT $427.36 — Flat (+0.12%) and consolidating near highs. No urgency; the 10% ($30K) slice has room to wait.
ASML $1,592 — Up +2.70%, trading well above consensus PT of $1,504. Momentum is strong but valuation is stretched. 20% ($60K) allocation needs conviction.
TSM $407.15 — Steady +1.38%. Holding near the $400–410 range. 25% ($75K) allocation zone is reasonable here.
Notable Catalysts & News
NVDA — Sell-the-news continues into Day 2 after the massive Q1 FY27 beat ($81.6B rev, Q2 guide $91B). Down -1.77% today after -2% after-hours yesterday. Broad AI supply chain surging around it while NVDA consolidates.
CRWV — Bouncing +6.22% off the sub-$100 floor from May 19 ($94.82 intraday low). Still in "stay away" territory per plan, but insiders may be exhausting selling pressure.
Networking/Optical Cluster — ANET (+5.77%), CIEN (+5.85%), COHR (+5.44%), AAOI (+6.99%), FN (+6.20%) all surging. AI infra buildout momentum spreading from compute into networking and optical interconnects.
MU — Strong +4.11% to $762.10. HBM demand tailwind accelerating. Memory sector broadly up (WDC +5.84%).
MRVL — +2.08% to $190.69 near 52-week highs ($193.32). AMD took a new $6.5M stake, signaling custom silicon partnership deepening.
ONTO — Slight weakness (-0.63%) after pricing $1.3B convertible notes at 0% coupon. Dilution overhang, but proceeds fund Rigaku acquisition for advanced process control.
AMKR — Worst performer at -3.78%. Packaging space seeing profit-taking after recent run.
