Reason: PLTR remains the basket's most extended short-term mover - 30D now +51.46%, RSI 69.3 - but 1-year change is only +17.82% with a negative 1-year alpha (-2.06), still reading as a short-window squeeze rather than confirmed leadership. MRVL stays the long-horizon-confirmed leader - 1-year change +180.49%, 45.7% above its 200-day, 1-year alpha +160.61 - a deep pullback (-34.33% off high), not a breakdown. ARM remains the weakest structurally at -47.19% off its 52-week high despite a positive 1-year change.

Tape Read

$PLTR is still the group's most extended chart: price $186.29, RSI 69.3 (elevated), death-crossed short-term, regime pullback, thesis intact, 7D +3.52%, 30D +51.46% (up from +44.45% last cycle), -10.23% off its 52-week high — but 1-year change is only +17.82% and 1-year alpha is -2.06, still negative: the sprint has widened but the year-over-year edge has not confirmed it. $MRVL remains the long-horizon-confirmed leader: price $216.62, RSI 47.2, golden-cross, regime pullback, thesis unrated, 7D -8.63%, 30D +32.57%, -34.33% off its high, 1-year change +180.49%, 45.7% above its 200-day average (vs 200-day), 1-year alpha +160.61 — a deep pullback inside a structurally intact uptrend, not a breakdown. $NVDA: price $217.55, RSI 52.3, golden-cross, regime basing, thesis intact, 1-year change +20.91%, vs 200-day +11.1%, 1-year alpha +1.04 — modestly intact, roughly market-matching. $AMZN: price $266.43, RSI 55.9, golden-cross, regime uptrend, thesis intact, 1-year change +15.04%, vs 200-day +11.6%, 1-year alpha -4.83 — still lagging the market over the year despite a positive 30D (+17.55%). $TSM: price $417.52, RSI 49.6, golden-cross, regime pullback, thesis unrated, 1-year change +75.23%, vs 200-day +13%, 1-year alpha +55.36 — deep pullback in an intact trend. $ARM: price $239.05, RSI 40, golden-cross, regime pullback, thesis intact-but-priced, 1-year change +67.7%, vs 200-day +19.9%, 1-year alpha +47.82, but still -47.19% off its 52-week high — the weakest structure in the group on distance-to-high even though the long horizon is still positive.

• $PLTR — WATCH: 30D +51.46%, RSI 69.3, but 1-year change only +17.82% and 1-year alpha -2.06 — a short-window squeeze, not a confirmed structural leader.
• $MRVL — PROMOTE: 1-year change +180.49%, 45.7% above its 200-day, 1-year alpha +160.61 — a deep pullback (-34.33% off high) inside a genuinely intact uptrend.
• $NVDA — WATCH: golden-cross, regime basing, thesis intact, 1-year change +20.91%, 1-year alpha +1.04 (roughly market-matching).
• $AMZN — WATCH: golden-cross, regime uptrend, thesis intact, but 1-year alpha -4.83 — lagging the market over the year.
• $TSM — WATCH: golden-cross, regime pullback, 1-year change +75.23%, 1-year alpha +55.36 — deep pullback in an intact trend.
• $ARM — WATCH: thesis intact-but-priced, 1-year change +67.7%, but -47.19% off its 52-week high — the weakest chart in the group on distance-to-high.

Lead pick: $PLTR is still the tape's most visible mover this cycle by magnitude, but its flat 1-year change and negative 1-year alpha keep the extension read as a short-window squeeze. $MRVL is the long-horizon-confirmed leader — 45.7% above its 200-day with a 1-year change of +180.49% — a deep pullback inside a genuinely intact structural uptrend, exactly the setup this desk looks for, not a breakdown.
