Reason: MRNA is now deep into monster territory — RSI 76.1 (up from 71.9 Wednesday), +29.11% on the week and +708.13% on the year, +209.5% against its 200-day; a September 25 aggregator item credits Phase 3 melanoma data that secured a presidential-symposium slot plus flu-shot availability, though the size of this move still has no filing-grade receipt behind it. TMO stays the cleanest structure and the RSI keeps climbing (72.5, up from 71.5), only -1.17% off its high, still no dated cause. AMGN (+7.51%) reclaimed ground. VRTX (+3.51%) was quiet. CRSP fell another 4.12% and its cushion above the 200-day has thinned to +1.7%, with the one-year slipping to -10.1% — the thinnest structure in the group is getting thinner. Roster unchanged.

Price/RSI Table

Status reads the 200-day trend first and RSI second; Action is a trend-hold lens — an extended name is never an entry, and a name below its 200-day with a negative year is not a dip.

What Changed Since 2026-09-23

• MRNA: RSI moved from 71.9 to 76.1, +29.11% week, +708.13% year, +209.5% against its 200-day. Its pull (refreshed September 25) carries a dated item crediting September Phase 3 melanoma data that secured a presidential-symposium slot and gains on flu-shot availability, alongside caution about valuation — the first item this desk has had naming a specific driver for this run, though it carries no specific day and the scale of the move still has no filing on file to match it.
• TMO: RSI moved from 71.5 to 72.5, +3.62% week, +46.99% year, now only -1.17% off its high. Its pull remains stale since September 18 — no news pulled for this week's continued grind higher.
• AMGN: +7.51% week; its pull (refreshed September 22) returns nothing newer than the September 10 analyst price-target items already on file — no new dated cause.
• VRTX: +3.51% week; its news file remains stale since April 14 — a failed pull, not evidence of no news.
• CRSP: -4.12% week, -8.44% month, its cushion above the 200-day narrowing to +1.7% (from +4.5%) with the year slipping to -10.1% (from -8.23%) — moving this one from a clean pullback read to a trend under test. Its pull (refreshed September 22) still only carries the same CASGEVY-momentum item flagged last time, unconfirmed by any filing.
• Roster unchanged since September 23: no entrants, no dropouts.
