Reason: TMO extended into genuinely overbought territory (RSI 62.3 to 71.0, +6.72% 7D) after two reads of being called a "steady climber"; AMGN kept climbing too, now just -5.06% off a fresh high; MRNA's decline deepened further (RSI down to 36.7, -33.39% off high); VRTX cooled modestly but stays structurally intact.

Tape Read

TMO is the surprise this week: what had been flagged a "steady climber" two reads running just crossed into overbought — RSI 71.0 (was 62.3), +6.72% 7D, +15.45% 30D, though it remains death-crossed even as short-term trend reads "up." AMGN kept its own streak going: RSI 64.1 (up from 57.5), +2.66% 7D, +7% 30D, golden cross, uptrend regime, now just -5.06% off its 52-week high — still the cleanest structure in the sector. MRNA's post-parabolic decline hasn't found a floor: RSI 36.7 (down from 45.9), a fresh -12.54% week (was -9.45%), now -33.39% off its 52-week high (was -27.78%) — still falling, not basing. VRTX cooled a step: RSI 49.2 (down from 53.4), -1.71% 7D, though its 30-day print is now slightly positive at +0.45% and it remains golden-crossed/uptrend.

• TMO — WATCH (downgraded from PROMOTE, extended): RSI 71.0 (up from 62.3), +15.45% 30D — the "steady climber" read just turned genuinely overbought; not a fresh entry at these levels despite the intact thesis flag.
• AMGN — PROMOTE: RSI 64.1 (up from 57.5), strong-up, golden cross, -5.06% off 52wk high — closing in on a fresh high, the sector's steadiest name for a fifth straight read.
• MRNA — PASS (still declining): RSI 36.7 (down from 45.9), -12.54% 7D, -33.39% off 52wk high — the round-trip from its parabolic run keeps deepening, no stabilization evidence yet.
• VRTX — WATCH: RSI 49.2 (down slightly from 53.4), golden cross intact, 30D +0.45% — the earlier de-risking has paused, still basing rather than confirming a reversal.

Lead pick: AMGN — still the least-drama chart in the sector and now the tightest to a fresh high. TMO is the one to watch: its jump into overbought RSI territory means the next print decides whether this was a healthy extension or the start of a cooldown.
