The sector's leadership week didn't carry into this one. The healthcare fund rose 0.61% against the S&P 500 proxy's 1.82% — a laggard week after last scan's outperformance — and $CVS is the reason the cut's bottom looks worse: it lost its 200-day this week, sliding from RSI 29.6 to 24.4, the cut's first capitulation print, on an old Q2 earnings recap that doesn't explain the fresh decline. At the top, $ATRC pushed past RSI 80 to 80.7 — the most extended name across the desk's healthcare coverage — while $MRNA and $TMO both crossed into the near-overbought band alongside it, and $BIIB jumped 13 RSI points with nothing in its news file to explain the move.

Data as-of the 2026-09-23 close (Wednesday's settled session) — every name in this cut carries a fresh bar; universe unchanged at 24 tickers.

Healthcare's week of leadership ended. The sector fund closed $168.80, up 0.61% on the week — positive, but behind the S&P 500 proxy's 1.82% gain over the same five sessions, a reversal from last scan when healthcare was the desk's best-performing sector fund against a falling index. The fund is also down 3.38% on the month even as it holds a 23.27% one-year return against the index's 15.77% — the short window and the long window are telling different stories here, and the long one is still the stronger trend.

$CVS is the week's break. It fell from RSI 29.6 to 24.4, the cut's first capitulation print, closing at $85.86 — down 6.39% on the week and now 1.8% below its 200-day, a line it had been sitting 1.8% above just one scan ago. The desk's news file for the name holds only an old Q2 2026 earnings recap (guidance raise, Rite Aid integration, GLP-1 partnerships) that was already reflected in prices weeks before this decline — no new driver is established for this week's move specifically.

The top of the cohort kept extending. $ATRC closed $59.96, RSI 80.7, up 4.94% on the week and 112.02% over three months, 67.7% above its 200-day — the most stretched name in this cut, with no news coverage newer than late July on the desk's record. $MRNA closed $182.11, RSI 71.9, up 25.06% on the week and 606.13% on the year, continuing the same extreme multi-quarter move this scan has tracked for weeks. $TMO crossed into the same near-overbought band at RSI 71.5. $ITGR held near its own extended perch at RSI 75.4, essentially flat on the week.

$BIIB is this scan's quieter surprise: RSI jumped from 50.4 to 63.4 on a 5.33% gain, and the desk's news file has nothing dated to the move. $GH cooled to a 0.81% weekly gain after last week's 13.98% surge, RSI 58.6 — a pause rather than a reversal, still up 195.23% on the year with no news file newer than September 4 to explain either the surge or the pause. $SYK and $UNH continue to sit in the cut's weakest structural group: $SYK at RSI 31.0 with a -26.8% year and 17.9% below its 200-day, $UNH at RSI 33.5 now just 4.6% above its own 200-day after a further pullback.

• $CVS lost its 200-day and fell into capitulation. RSI 29.6 → 24.4, -1.42% on the day to $85.86; the cushion above its 200-day flipped from +1.8% to -1.8%. The year-over-year return shrank from +19.4% to +12.24%.
• $ATRC pushed past RSI 80. RSI 77.7 → 80.7, +1.92% on the day to $59.96, now the most extended name in this cut.
• $MRNA and $TMO both crossed into the near-overbought band. MRNA: RSI 63.3 → 71.9, +25.06% on the week. TMO: RSI 67.6 → 71.5, +2.6% on the week.
• $BIIB jumped 13 RSI points with no driver on the desk's record. RSI 50.4 → 63.4, price $215.50 → $227.53 (+5.6%).
• $AMGN exited the oversold band entirely. RSI 39.7 → 51.9, price $385.65 → $406.09 (+5.3%).
• $GH cooled from last scan's surge. RSI 63.1 → 58.6, price $179.38 → $176.31 (-1.7%) — a pause, not a reversal, still +195.23% on the year.
• The sector flipped from leader back to laggard versus the index. The fund's 7-day return went from +1.83% (leading a falling market) to +0.61% (trailing a rising one).
• The oversold band shrank and shifted. $CVS moved from oversold into capitulation; $ZTS, $UNH, $HROW, $SYK remain, while $ABT and $AMGN exited into neutral territory.
• No stale bars this scan — every name carries a fresh 2026-09-23 close. Universe unchanged at 24 tickers.

RSI is a fourteen-session stretch gauge: under 30 oversold, under 25 capitulation, over 70 near-overbought, over 80 extreme. The one-year return and the distance to the 200-day average decide whether a name is in a pullback or a downtrend, and in this cut they still contradict the RSI in both directions. $ISRG prints 62.0 on a long trend that remains broken (-11.04% year, 12% below its 200-day). $CVS just fell into capitulation on a trend that, until this week, was still passing the long test — its year is still positive at +12.24%, which makes this a fresh break rather than a continuation of an old one. Five names fail the long test outright — $SYK, $ZTS, $HROW, $ABT and $ISRG, all below their 200-day with negative years. $CVS and $VEEV sit in the ambiguous middle: $CVS just crossed into failing, $VEEV carries a negative year while trading 35.7% above its 200-day. Everything else in the cut is above its long average with a positive year, which is why the sector's underperformance this week reads as a pause inside a working trend rather than a reversal.

$CVS (24.4) — new this scan, lost its 200-day in the same move. No news file explains the additional decline.

$SYK (31.0), $UNH (33.5), $HROW (35.8), $ZTS (39.8) — four names, down from seven last scan ($CVS moved into capitulation, $ABT and $AMGN exited into neutral). $UNH is the only one still barely passing the long test.

• Failing the long test: $ABT, $ISRG — below their 200-day with negative years. $ISRG's 62.0 RSI does not change that.
• Negative year, above the 200-day: $MDT and $VEEV — the ambiguous middle; $VEEV is 35.7% above its long average with a -2.9% year.
• Pullback, trend intact: $LLY, $VRTX — above their 200-day with positive years, near their 20-day.
• Healthy and working: $XLV, $AMGN, $DXCM, $JNJ, $MRK, $GH, $PFE, $GILD, $BIIB.
• Near-overbought, trend intact: $TMO, $MRNA.
• Extended: $ITGR (75.4, holding near its high) and $ATRC (80.7, the most stretched name in the cut) — working trends at extreme prices.

• $CVS lost its 200-day this week with no new driver on the record — its only recent news is an old Q2 earnings recap already priced in weeks ago. The next question is whether $78.94, the prior support shelf, holds if the slide continues.
• $ATRC crossed above RSI 80 for the first time this scan has tracked it, 67.7% above its 200-day with no news coverage newer than late July. Whether it consolidates or gives back the 21.67% it added on the month is the cut's most stretched open question.
• $BIIB jumped 13 RSI points on a 5.33% week with no news receipt covering it. Does a filing or transcript surface, or does this stay unexplained inside an already-healthy trend?
• The sector fund trailed the index this week after leading it last scan. Whether that is noise inside a still-strong one-year trend (+23.27%) or the start of a real rotation away from healthcare is worth checking against next week's cross-sector read.
• $GH cooled after last scan's 13.98% surge with still no news file newer than September 4. Getting a fresh pull on the name should be a priority before the next scan tries to explain either move.
