Reason: Biotech is split. $MRNA carries an enormous one-year gain and sits far above its 200-day, $TMO is in a clean uptrend, while $VRTX and $AMGN are in pullbacks (weak short-term trend, RSI under 50) inside intact one-year gains. $CRSP is the broken one: negative one-year change and negative alpha, only barely above its 200-day.

Price/RSI Table

As of 2026-10-02. 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 2026-09-25

• VRTX/AMGN: down on the week and month, still above their 200-day; flag-type pullbacks, not breakdowns.
• CRSP: 200-day is the level to watch; the year is negative.
• No dated cause on file for any move in this group (TMO news re-pulled 2026-10-03 with no item on a move; the other receipts predate October 2; stock-events and the October 1-2 captures checked).
• Roster unchanged since September 25: no entrants, no dropouts.
