Reason: MRNA posted an extreme within-cycle move - 7D +129.02%, 30D +149.92%, change1y +453.51% - the sharpest number on the desk this cycle; cause unknown, no capture/news receipt read this session. AMGN and TMO both sit near fresh 52-week highs in breakout/uptrend regimes with strongly positive change1y and alpha1y; VRTX rounds out a cohort where all four names are golden-crossed and above their 200-day with positive alpha1y - a genuinely strong group, not a short-window pop.

Tape Read

$MRNA posted the most extreme move on the desk this cycle: price $145.13, RSI 71.6 (near-overbought), golden-cross, regime pullback, thesis unrated, 7D +129.02%, 30D +149.92%, change1y +453.51%, 197.8% above its 200-day average (vsSma200), alpha1y +431.69 — still -17.85% off its 52-week high despite the size of the move. This is an extraordinary, code-computed print; cause unknown — no capture or news receipt was read this session, so no driver is claimed. $AMGN: price $439.33, RSI 73.4 (near-overbought), golden-cross, regime breakout, thesis unrated, 7D +5.82%, 30D +20.02%, just -0.87% off its 52-week high, change1y +48.54%, vsSma200 +24.5%, alpha1y +26.73 — genuinely intact strength, not just a short-window pop. $TMO: price $629.27, RSI 74.6 (near-overbought), golden-cross, regime uptrend, thesis intact, 7D +7%, 30D +19.53%, -2.29% off its high, change1y +30.08%, vsSma200 +17.9%, alpha1y +8.26. $VRTX: price $548.05, RSI 67, golden-cross, regime breakout, thesis unrated, 7D +8.38%, 30D +15.97%, -1.31% off its high, change1y +37.89%, vsSma200 +19.1%, alpha1y +16.07.

• $MRNA — WATCH: 7D +129.02%, 30D +149.92%, change1y +453.51% — the desk's sharpest print this cycle; RSI 71.6 argues for caution, and no source confirms a driver (cause unknown).
• $AMGN — PROMOTE: RSI 73.4, golden-cross, regime breakout, -0.87% off its 52-week high, change1y +48.54%, alpha1y +26.73 — genuinely intact, not just extended.
• $TMO — WATCH: golden-cross, regime uptrend, thesis intact, change1y +30.08%, alpha1y +8.26.
• $VRTX — WATCH: golden-cross, regime breakout, change1y +37.89%, alpha1y +16.07.

Lead pick: $MRNA's move is the largest number on the desk this cycle by a wide margin, but the size and speed (129% in a week) argue for treating it as an outlier requiring verification rather than a clean promote — cause unknown, no corpus source read this session. $AMGN is the cleanest confirmed leader: near a fresh high, RSI elevated but the year (+48.54%) and alpha (+26.73) back up the breakout regime rather than just a short-window extension.
