Data as-of 2026-08-14 close — every name in this cut carries a fresh bar this scan.
The oversold band didn't empty, it changed occupants: DNA fell into it this scan (RSI 43.8 → 34.5, -14.8% over the week) while ALNY (34.2 → 40.3) and LEGN (39.6 → 40.6) both climbed just clear of the line. COGT (60.7 → 44.8) and NKTR (66.1 → 53.5) posted the cut's two sharpest reversals, each losing more than 12 RSI points. On the other side, KYMR posted the largest gain in the cut (51.7 → 64.6, +12.9), and MDT (62.3 → 71.4) and PTGX (64.7 → 71.2) both crossed into overbought this scan — four names above RSI 70 now, versus three last scan — while TMO (71.6 → 63.2) fell back out and REGN (80.0 → 76.9) eased slightly but stayed the cut's highest print.

Quick Snapshot
| Signal | Reading |
|---|---|
| Overall | 🟡 The oversold band swapped occupants rather than staying empty — DNA fell in as ALNY and LEGN climbed out — while the overbought band grew from 3 names to 4 |
| Leaders | KYMR (RSI 64.6, the cut's biggest single-scan gain, +12.9); MDT (71.4, newly overbought); PTGX (71.2, newly overbought) |
| Laggards | DNA (34.5↓, fell into the oversold band, -14.8% this week); COGT (44.8, -15.9-point RSI drop); NKTR (53.5, -12.6-point drop) |
| Key insight | Three of last scan's four "collapse"-regime names (SRPT, DNA, ISRG) upgraded to "downtrend" this scan — but DNA's price action got worse even as its regime label improved, so regime and RSI are pulling in opposite directions for that name |
What's Going On
DNA was the session's standout decliner. RSI fell from 43.8 to 34.5, dropping into the 25-40 oversold band on a -6.22% single day and -14.81% week (change1d, change7d per biotech-scan.json), and its 30-day return worsened to -24.56%. Its regime classifier moved from "collapse" to "downtrend" — technically an upgrade — but that improvement sits awkwardly against a price chart that's still getting worse, not better.
ALNY and LEGN, last scan's two oversold names, both cleared the band by a hair: ALNY 34.2 → 40.3, LEGN 39.6 → 40.6. Both keep their "collapse" regime tag despite the move, the same lag between RSI and structural read flagged last scan. Three other names that carried "collapse" tags last scan — SRPT, DNA, and ISRG — all moved to "downtrend" this scan; only IONS remains tagged "collapse" among that original group.
COGT and NKTR posted the cut's sharpest reversals. COGT's RSI dropped from 60.7 to 44.8 (-15.9 points) on a -10.52% week even as its own single-day move was positive (+1.66%), and its regime downgraded from the uptrend/breakout tier into "pullback." NKTR fell from 66.1 to 53.5 (-12.6 points) on -4.52% over the week and -3.82% in a single day, though its regime held at "pullback" throughout — no downgrade despite the drop.
KYMR led the gainers: RSI climbed from 51.7 to 64.6 (+12.9 points) on +9.18% over the week and +42.79% over three months (change3m), staying in its already-confirmed "uptrend" regime. MDT and PTGX both crossed above RSI 70 for the first time this cut has shown this cycle — MDT 62.3 → 71.4 on +13.42% over 30 days, PTGX 64.7 → 71.2 on +14.5% over 30 days — joining REGN (76.9, still the cut's highest print despite easing from last scan's 80.0) and AMGN (72.3 → 70.3, holding just above the line). TMO fell the other way, dropping out of overbought entirely (71.6 → 63.2, -8.4 points).
What Changed Since Prior Scan (2026-08-08)
- DNA fell into the oversold band. RSI 43.8 → 34.5, -14.8% over the week, 30-day return worsened to -24.6% — the cut's steepest single-name decline this scan.
- ALNY and LEGN both climbed just clear of the oversold band. ALNY 34.2 → 40.3, LEGN 39.6 → 40.6 — both retain a "collapse" regime tag despite the move.
- Three of last scan's four "collapse" names upgraded to "downtrend." SRPT, DNA, and ISRG all moved off the "collapse" tag; only IONS still carries it.
- COGT posted the cut's sharpest downgrade. RSI 60.7 → 44.8 (-15.9), regime dropped from the uptrend/breakout tier to "pullback."
- NKTR dropped 12.6 RSI points without a regime downgrade. RSI 66.1 → 53.5, regime held at "pullback" both before and after.
- KYMR posted the cut's largest gain. RSI 51.7 → 64.6 (+12.9), regime unchanged at "uptrend."
- MDT and PTGX both crossed above RSI 70. MDT: 62.3 → 71.4. PTGX: 64.7 → 71.2. Four names now sit above 70 (REGN, AMGN, MDT, PTGX), versus three last scan.
- TMO fell out of overbought. RSI 71.6 → 63.2 (-8.4).
- REGN eased from the cut's all-time-scan high but stayed the top print. RSI 80.0 → 76.9, still +20.9% over 30 days.
- No stale bars this scan — every name carries a fresh 2026-08-14 close.
- Universe unchanged. Same 39 tickers as the August 8 cut — no entrants or dropouts.
How To Read The Board
RSI measures how stretched a stock is over the past 14 sessions — under 30 signals oversold, over 70 signals overbought/extended. vs SMA20 is the price gap to the 20-day average; a large negative number means a fast recent decline. vs VWAP is the premium (or discount) versus the average price paid by everyone still holding — a big positive number means most of a name's move is unrealized gain that can get sold into weakness. Trend pairs direction/strength with a cross signal: GC (golden cross, the short-term average above the long-term average) is structurally healthier than DC (death cross). This scan's DNA move is the clearest example of why regime and RSI need to be read together: DNA's regime label improved (collapse → downtrend) at the exact moment its price action deteriorated (RSI fell into the oversold band, 30-day return worsened) — a reminder that a "better" regime tag doesn't always mean a better tape.

Tier Analysis
Extreme Oversold (RSI < 25)
None.
Oversold band (RSI 25-40)
The band swapped occupants rather than emptying this scan: last week's two residents both climbed just clear of the line (ALNY and LEGN, readings in the What Changed section above), and the week's steepest decliner took their place. DNA (34.5) is that name, having fallen in from 43.8.
Neutral and stronger (everyone else)
- Collapse-regime tier: ALNY, LEGN, IONS — the three names still carrying the "collapse" tag; ALNY and LEGN have cleared the oversold band on RSI but the structural read hasn't caught up.
- Downtrend-regime tier: NTLA, RXRX, RARE, SRPT, DNA, ISRG — DNA and its 30-day return keep worsening even though its regime label improved this scan.
- Pullback-regime tier: NVO, MRNA, BEAM, EDIT, DHR, LABU, NKTR, COGT — COGT and CRSP newly joined this tier this scan.
- Basing-regime tier: GILD, BNTX — the cleanest reads in the cut.
- Uptrend/breakout tier: ABBV, REGN, BIIB, LLY, VRTX, BMRN, INCY, ILMN, PTGX, IQV, XBI, IBB, IBBQ, KYMR, AMGN, TMO, A, DXCM — 18 names; MDT, PTGX, REGN, and AMGN are the four extended above RSI 70.
Entry Zones
| Stock | Price | Zone | RSI | 30D% | Setup |
|---|---|---|---|---|---|
| DNA | $6.79 | No support shelf identified | 34.5 | -24.6% | Fell into the oversold band this scan on a steep weekly decline; no confirmed floor |
| GILD | $138.36 | <$136.01 (support shelf) | 62.4 | +5.1% | Basing regime, cooled, tight to its own shelf |
| COGT | $37.93 | <$36.35 (support shelf) | 44.8 | -3.5% | Regime downgraded to "pullback" after a sharp weekly drop; sits just above its shelf |
| REGN | $803.48 | Extended — no clean entry | 76.9 | +20.9% | Still the cut's highest RSI print despite easing from last scan's 80.0 |
| MDT | $91.27 | <$90.15 (support shelf) | 71.4 | +13.4% | Newly crossed above RSI 70 this scan, tight to its shelf |
Action Matrix
| Action | Stocks | Why |
|---|---|---|
| 📈 ACCUMULATE | GILD, BNTX | Basing regime, cooled, not extended |
| 🔒 HOLD | ABBV, BIIB, LLY, VRTX, BMRN, INCY, ILMN, IQV, XBI, IBB, IBBQ, KYMR, A, DXCM, TMO | Uptrend/breakout regime, not extended into the cut's most stretched names |
| 🔍 WATCH | NVO, MRNA, BEAM, EDIT, DHR, LABU, NKTR, COGT, CRSP | Pullback-regime names, mixed signal, no confirmed direction |
| ⚠️ AVOID / DON'T CHASE | REGN, AMGN, PTGX, MDT | All four above RSI 70 this scan — extended, wait for a pullback |
| ❌ AVOID / FALLING KNIFE | ALNY, LEGN, IONS, NTLA, RXRX, RARE, SRPT, DNA, ISRG | "Collapse" or "downtrend" regime — structurally the most damaged names in the cut |
What To Watch Next
- DNA fell into the oversold band this scan while its regime label improved to "downtrend" — does the price stabilize, or does the regime downgrade lag the tape the way ALNY's did?
- ALNY and LEGN both cleared the oversold band by a hair but keep their "collapse" tag — does either finally earn a regime upgrade, or does the relapse resume?
- MDT and PTGX both crossed into overbought this scan, joining REGN and AMGN — does the group extend further, or does it give this back the way TMO's did this scan?
- COGT and NKTR both posted double-digit RSI drops without matching regime downgrades (NKTR) or with a clean downgrade (COGT) — does either stabilize, or does the damage spread to the rest of the pullback tier?
