A blended fair-value estimate combining up to six valuation methods. Each method is weighted by how well it fits the company — DCF down-weights for unprofitable names; DDM only fires for steady dividend payers; comparables down-weight when peer multiples disagree.
- DCF (quality-aware) — projects free cash flow with a horizon that scales to business quality. True compounders (quality 6/6) get 10 years explicit + 10 years fade before terminal; cyclical/struggling names (quality 0-1) get a 5-year terminal cliff. Quality is scored from ROE, gross margin, growth, FCF margin, debt load, and FCF consistency — the same factors that drive market premium for compounders.
- Market-Implied Growth (in Model Inputs) — reverse-DCF that answers "what growth rate is the market pricing in?". Lets you sanity-check the deviation: if implied growth is plausible for the business, the model's bearish flag may be wrong; if implausible, the market may be over-extrapolating.
- DDM (Gordon Growth Dividend Model) — values the stream of future dividends. Only used when trailing yield ≥ 2% and dividend payments are stable — below that the dividend is a token payout and Gordon (which values only the dividend stream) systematically underprices growth names, so those route to DCF + comparables + market anchor instead.
- P/E, EV/EBITDA, P/B, P/S — applies the peer-group median multiple to this company's per-share metric. Peers come from the same set as the "Related symbols" card. Earnings/sales metrics are forward-tilted by the company's recent revenue growth (capped at 25%) so they're comparable to peers' growth-embedded multiples — mimics how analysts use NTM rather than TTM. Per-multiple weights are biased by company quality (e.g. P/B down-weighted for asset-light tech).
- Market Anchor (SMA50) — the 50-day moving average, weighted by recent trading-range stability (tighter Bollinger bands → higher weight). Captures information fundamentals miss (forward consensus, sentiment, supply/demand) — but only when recent trading is steady enough that the market has converged on a view. During wild breakouts or breakdowns the anchor's weight collapses.
- Options Expected (B-L 30d) — the risk-neutral expected stock price at 30-day options expiration, derived from the full implied-volatility surface via Breeden-Litzenberger (second derivative of call price wrt strike → implied PDF, then E[S_T]). Forward-looking, captures all options-implied information (smile, skew, term structure) in one number. Weighted by chain liquidity. SP500-only at present (pre-computed daily). Backtest evidence: adds modest alpha across most bucket × holding combos.
- Blended value — weighted average. Confidence reflects how many methods fired and how tight peer dispersion is.
- Deviation pill — green when blended FV ≥ 10% above current price (undervalued); red when ≥ 10% below; grey otherwise.

Quick-reference for reading the values below. Indicators combine to confirm a view — no single one is a trade signal on its own.
- SMA 20 / 50 / 200 — price above = uptrend, below = downtrend. SMA 50 crossing SMA 200 is the golden/death cross.
- EMA 12 / 26 — faster-reacting averages; 12 above 26 is short-term bullish.
- MACD — bullish when MACD > signal (green badge), bearish when below. Divergence from price often precedes reversals.
- ADX (14) — trend strength regardless of direction. <20 range, 20–25 weak trend, 25–50 trend, >50 strong trend.
- +DI / −DI — +DI > −DI favors bulls; the reverse favors bears. Read alongside ADX.
- RSI (14) — <30 oversold, >70 overbought. 40–60 is neutral; trending names can stay extreme.
- Stochastic %K / %D — <20 oversold, >80 overbought. %K crossing %D is an early momentum signal.
- Williams %R — inverted scale: <−80 oversold, >−20 overbought.
Oscillators work best in range-bound markets; in strong trends they give premature reversal signals.
- Bollinger Bands — price at upper band = overbought, lower = oversold. Narrow bands (squeeze) often precede expansion.
- OBV — cumulative volume; rising OBV confirms uptrend, falling OBV confirms downtrend. Divergence from price is a warning.
- Vol SMA 20 / Vol ROC — today's volume vs. 20-day average. Positive ROC with price move = conviction.
- ATR / True Range — average daily $ move; sizing and stop-loss reference.
- HV 20 / 30 / 60 — realized (historical) volatility. Compare to IV on the options cards: IV > HV = rich premium.
Confluence matters: trend + momentum + volume agreeing carries far more weight than any single indicator. For how these feed the spread scanner score, see the algorithm docs →

Data Summary
ARWR Stock Analysis Report
Executive Summary
Overall Assessment: BEARISH | Confidence Level: 8/10
ArrowHead Research (ARWR) is signaling a strong downtrend with converging bearish technical indicators and elevated volatility. The stock has broken below key moving averages and is trading near oversold conditions, but the overwhelming negative momentum suggests further downside before any meaningful relief rally. While recent news headlines reflect positive industry tailwinds (RNA therapeutics expansion, CRISPR adoption, complement inhibitors market growth), these macro-positive narratives have failed to arrest the stock's technical deterioration, indicating that company-specific or portfolio-level headwinds are dominating.
Investment Thesis: ARWR is in active downtrend (price $58.13 vs SMA200 $72.26, -19.5% discount) with RSI at 26.34 (oversold) and MACD deeply negative (-4.87 histogram), but put/call volume ratios (2.01) and elevated historical volatility (HV60 59.6%) suggest institutional unwinding. The technical deterioration significantly outweighs positive industry sentiment, creating asymmetric downside risk until technical stabilization occurs.
Recent News Sentiment Impact: POSITIVE headlines regarding RNAi therapeutics, oligonucleotide CDMO expansion, and complement inhibitor adoption suggest favorable market conditions for ARWR's pipeline. However, the disconnect between positive news and negative price action is a critical red flag—this suggests either company-specific execution concerns, clinical trial setbacks, or portfolio rebalancing overriding sector momentum.
Technical Analysis
Trend Direction
| Timeframe | Direction | Strength | Status | |-----------|-----------|----------|--------| | Short-term (1-4 weeks) | BEARISH | STRONG | In downtrend; price below SMA20 ($64.67) | | Medium-term (1-3 months) | BEARISH | STRONG | Price below SMA50 ($77.35) by -24.8%; bearish structure intact | | Long-term (3-12 months) | BEARISH | MODERATE | Price below SMA200 ($72.26); 19.5% discount suggests structural weakness |
Support/Resistance Levels
| Level | Type | Distance | Significance | |-------|------|----------|---------------| | $70.97 | Resistance (BB Upper) | +22.1% | Bollinger Band upper band; strong resistance | | $64.67 | Resistance (SMA20) | +11.2% | 20-day MA; short-term trend barrier | | $62.93 | Resistance (EMA12) | +8.3% | 12-day EMA; immediate overhead resistance | | $58.38 | Support (BB Lower) | +0.4% | Bollinger Band lower band; extremely close to current price | | $55.00 | Support (Psychological) | -5.4% | Round number; potential consolidation floor | | $50.00 | Support (Technical) | -14.0% | Extended downside target if breakdown accelerates |
Critical Observation: ARWR is trading just above its lower Bollinger Band ($58.38), indicating the stock is at an extreme technical extreme. Any break below $58.38 would represent a breakdown from the current volatility envelope, potentially triggering capitulation selling.
Momentum Signals
RSI (14): 26.34 — OVERSOLD SIGNAL
- Reading below 30 indicates oversold conditions, historically associated with short-term bounce potential
- However, RSI can remain oversold for extended periods during strong downtrends (see strong ADX reading below)
- Does NOT guarantee immediate reversal; often precedes further weakness in bearish regimes
MACD: -4.88 / Signal: -0.01 / Histogram: -4.87 — DEEPLY BEARISH
- Large negative histogram (-4.87) indicates MACD is far below signal line
- MACD is in negative territory with -4.88 reading, confirming bearish momentum
- Signal line at -0.01 (near zero) shows momentum has been deteriorating, not stabilizing
- No bullish crossover in sight; bearish trajectory continues
Bollinger Bands: PRICE AT LOWER BAND — EXTREME OVERSOLD
- Price ($58.13) is 0.4% above lower band ($58.38)
- Band width of 19.47 is moderate, not suggesting imminent squeeze breakout
- Oversold positioning typically precedes mean-reversion moves, but given strong trend strength (ADX 35.78), mean reversion may not occur until downtrend exhaustion
Volume Analysis
| Metric | Value | Interpretation | |--------|-------|-----------------| | Volume SMA 20 | 2,329,564 | 20-day average volume baseline | | Volume Rate of Change | -22.22% | CRITICAL: Volume declining significantly; less conviction in recent moves | | On-Balance Volume | -12,068,736 | NEGATIVE: Cumulative volume suggests distribution, not accumulation | | Institutional Interest | DECLINING | Volume declining during downtrend suggests institutional exit, not accumulation |
Volume Interpretation: The -22.22% volume rate of change is a concerning sign during a downtrend. While declining volume sometimes suggests exhaustion, it can also indicate institutional liquidation following a cascading sell-off. The negative OBV confirms that on each price decline, volume exceeded on each rise, showing net selling pressure. This is bearish despite the technical oversold reading.
News & Sentiment Analysis
Recent Headlines Summary
All six recent headlines reflect positive industry trends surrounding ARWR's core therapeutic areas:
- HoFH Market Growth (7MM) — RNAi therapeutics driving expansion in familial hypercholesterolemia treatment
- Oligonucleotide CDMO Market — $9.87B market forecast by 2031; RNA-targeted drug pipelines expanding (ARWR's core platform)
- Complement Inhibitors Market — Strong outlook for C5/C3-targeted drugs (relevant to ARWR pipeline)
- IgA Nephropathy — Novel therapies driving expansion in kidney disease market
- CRISPR Therapeutics — Momentum in gene therapy adoption (adjacent to ARWR's genetic medicine focus)
- Idiopathic Pulmonary Fibrosis — 80+ leading companies, 100+ novel treatments in pipeline
Sentiment Assessment
- Aggregate News Sentiment: POSITIVE (5/6 headlines)
- Sentiment-to-Price Disconnect: SEVERE
This is a critical divergence: industry fundamentals and market opportunities are expanding robustly, yet ARWR has declined significantly. This suggests:
- Company-specific execution risk (trial failures, program delays, competitive pressure)
- Portfolio rebalancing by large shareholders
- Valuation concern (stock priced as if opportunities won't materialize)
- Recent catalyst miss not yet reflected in news headlines
Catalyst Identification
| Catalyst | Date | Impact | |-----------|------|--------| | Earnings Release | 2026-11-24 | 56 days; material update on pipeline progress, patient enrollment, revenue | | Previous Earnings | 2026-08-04, 2026-05-07, 2026-02-05 | Quarterly cadence; likely contains recent company updates | | Industry Conference Season | Q4 2026 | Market access updates, partnership announcements |
Critical Gap: No recent (last 30-day) company-specific news in provided headlines. The most recent article is dated 2026-09-30 (market research, not company news). This 3-4 week gap between last earnings (presumed Q3 around late August) and current analysis suggests either:
- Negative Q3 results triggered recent sell-off
- Silent period before earnings announcement (Nov 24)
- No major announcements made
Market Narrative Conflict
| Signal | Message | Status | |--------|---------|--------| | Technical | Bearish downtrend, capital flight | STRONG | | News | Industry tailwinds, market expansion | MODERATE-STRONG | | Options | Elevated volatility, puts/calls imbalanced 2:1 | BEARISH | | Volume | Declining conviction; distribution pattern | BEARISH |
Narrative Assessment: The market is pricing in execution risk or near-term disappointment that news headlines

Estimated net dealer gamma is at the 5th percentile of this name's own daily history, near the low end of its range. This describes current positioning; it is not a forecast or a trading signal.
Net dealer gamma is an estimate of the aggregate gamma held by options market makers across this name's option chain, weighted by open interest. Dealer positions aren't public, so it uses a standard simplifying assumption: dealers are treated as long the calls and short the puts that are open. Actual dealer books can differ.
Gamma percentile ranks today's estimate against this name's own daily history, from 0% (the lowest reading on record) to 100% (the highest). Raw gamma scales with how much open interest a chain carries, so it isn't comparable across names; the percentile is. The badge marks the bottom 20% as low and the top 20% as high.
Tilts run from −1 to +1 and show how lopsided the estimated dealer exposure is. GEX tilt compares call gamma with put gamma. Vanna tilt describes how the hedge would shift if implied volatility changed, and charm tilt how it would shift with the passage of time.
This card describes estimated positioning and where it sits historically. It is not a forecast of price direction or volatility and not a trading signal. Market-wide view: Dealer positioning screener.
IV(put wing) − IV(ATM), in vol pointsHow much the OTM put trades above (or below) the at-the-money strike. Measures the height of the put-side tail relative to ATM — i.e. how expensive crash insurance is on this name.
- Positive (typical) — wing IV > ATM IV. Standard equity put skew: portfolios bid up crash protection, so OTM puts trade richer than ATM.
- Near zero or negative (unusual) — wing IV ≤ ATM IV. Flat or inverted put side. Common when there's no fear demand, in tightly mean-reverting names, or right after an earnings catalyst clears.
- Percentile vs own 3-yr history: high = wings rich (good time to sell wing premium); low = wings cheap (good time to buy protection).
- Not directional — high or low wings don't predict up or down moves. It's a price tag on tail insurance, not a forecast.
IV(call wing) − IV(put wing), equal delta on each sideWhich side of the smile is the market paying up for? Measures the tilt of the surface — call skew vs put skew at matched deltas.
- Negative (typical) — puts richer than calls. Standard equity behavior: hedging demand makes puts carry a premium. Most large-caps sit in the −1 to −5 vol-point range.
- Strongly negative (< −5 pts) — heavy downside hedging, elevated fear, or an upcoming catalyst (earnings, FDA, macro event). Worth flagging.
- Positive — calls richer than puts. Unusual for equities; signals bullish momentum, short-squeeze positioning, or takeover/M&A speculation.
- Near zero — symmetric surface. Market sees roughly equal up/down risk. Rare for large-caps; more common in commodities and FX.
Wing-vs-ATM tells you how expensive the tails are. Risk Reversal tells you which side is favored. Combined:
- High wing percentile + deeply negative RR → strong put bid; stress or major event priced in. Owning protection costs a premium; selling put premium is dangerous.
- Low wing percentile + near-zero RR → complacency; insurance cheap and balanced. Good environment to add cheap downside hedges.
- Positive RR + elevated wings → call-side fear-of-missing-out; common in squeeze setups. Upside calls expensive, downside puts not bid.
Percentile is the rank of today's reading within ~3 years of this symbol's own history. High percentile = wings are rich relative to history; not a directional signal. Skew is read off the chain in real time, not from CBOE SKEW.

ARWR Proposed Insider Sales (Form 144)
Latest: 2026-08-18What is Form 144? A notice of intent to sell restricted or control stock under Rule 144. Affiliates (officers, directors, 10%+ owners) and holders of restricted shares must file Form 144 when planning to sell more than 5,000 shares or $50,000 in any 3-month rolling window.
How it relates to Form 4: Form 144 is filed before the trade (up to 90 days in advance); Form 4 is filed within 2 business days after the trade executes. Not every Form 144 results in a sale — the filer may cancel or delay. Look for the corresponding Form 4 on the Insider Activity card to confirm a sale actually happened.
10b5-1 plans: Trades made under a pre-scheduled Rule 10b5-1 plan are not discretionary — they execute automatically on dates set months earlier, regardless of news. High 10b5-1 percentages mean less per-filing signal value, though cumulative selling volume still matters.
"Notice value": Aggregate market value the filer wrote into the Form 144 — i.e. the size of the planned sale, not necessarily the executed dollars. An amended notice (Form 144/A) replaces the original it amends, and cancelled notices are dropped, so neither is double-counted above. A filed value that is clearly inconsistent with the share count at the stock's price (a filer typo) shows as a dash and is left out of the totals.
Source & freshness: Sourced from public Form 144 filings. Refreshed daily; new filings typically appear here the morning after they are filed.

Quarterly filings sourced from SEC 10-Q / 10-K reports. TTM tiles aggregate the most recent four quarters; bars show the last ~12 quarters oldest → newest.
- Revenue — top-line sales. Look for consistent YoY growth; seasonal businesses need same-quarter comparisons (Q4 '24 vs Q4 '23).
- Net Income — bottom-line profit after all expenses. Can be volatile from one-time items; red bars = net loss.
- Diluted EPS — net income per share assuming options/converts are exercised. Direct input to the P/E ratio.
- Operating Cash Flow — cash generated from core operations, before capex and financing. Harder to manipulate than net income; growing OCF is a quality signal.
- Sequential growth — quarter-over-quarter trend. Accelerating bars are a momentum signal.
- YoY growth — compare to the same quarter a year earlier to remove seasonality.
- Quality — OCF should roughly track Net Income over time. Large divergence (net income ≫ OCF) flags accruals risk.
- Margins — scan the bar ratios: Net Income / Revenue tells you margin trend without needing a separate chart.
TTM (trailing-twelve-month) smooths seasonality and is used for the P/E calculation. Filings appear 30–90 days after the period closes.

Ratios derived from TTM financials and the current market price, sampled daily. History chart shows how expensive the stock is today relative to its own recent past.
- P/E — price / TTM earnings. Rough market rule: 10–15 value, 15–25 market, >30 growth/premium. Negative when earnings are negative.
- P/B — price / book value. Useful for financials and asset-heavy names; meaningless for asset-light software.
- P/S — price / TTM revenue. Useful when earnings are negative or noisy (early-stage growth).
- EV/EBITDA — capital-structure-neutral. <10 cheap, 10–15 reasonable, >20 rich. Good for comparing across leverage profiles.
- EV/Sales — like P/S but accounts for debt + cash. Compare within sector.
- ROE — return on equity. >15% strong, >25% exceptional. Caution: high leverage inflates ROE.
- ROA — return on assets. Leverage-neutral; >5% solid, >10% exceptional.
- Div Yield — annual dividend / price. Compare to 10Y Treasury; sustained yield >6% often signals distress.
- FCF Yield — free cash flow / market cap. >5% is attractive; negative means burning cash.
- Debt/Equity — leverage. <1 conservative, >2 aggressive. Sector-dependent (utilities naturally high, tech low).
- Current Ratio — short-term liquidity. >1.5 comfortable, <1 raises short-term solvency flags.
- Compare current level to the 3-year band: near the high end = relatively expensive; near the low = relatively cheap.
- Multiples expanding while earnings are flat = sentiment-driven rally.
- Multiples compressing while earnings grow = value coming from fundamentals.
Regulatory short-interest reports publish on a bi-weekly settlement cadence; short-volume is reported daily by the trade-reporting facilities. Float is derived from insider-ownership filings.
- Short Interest — total shares currently sold short as of the settlement date. Lags real time by ~8 business days.
- SI % of Float — short interest / free float. The key crowding metric.
- Days to Cover — short interest / avg daily volume. How many full trading days it would take shorts to buy back. High DTC + catalyst = squeeze fuel.
- Short Vol Ratio — today's short-sale volume / total volume. Intraday selling pressure proxy (not the same as short interest).
- Free Float — shares available for public trading (total shares minus insider / restricted).
- Float % — free float / shares outstanding. <50% = tightly held, more prone to squeezes.
- SI % of Float < 5% — typical, no particular signal.
- 5–15% — elevated; watch for catalysts (earnings, guidance, macro).
- 15–30% — heavily shorted; tight-float names in this range have produced notable squeezes historically.
- >30% — extreme; borrow is likely expensive and squeeze risk is material.
- Days to Cover > 5 combined with high SI% amplifies squeeze potential.
- Trend matters more than level. Rapidly rising short interest often precedes negative catalysts or heavy hedging.
- A sudden drop in SI after a rally may indicate a squeeze in progress.
Short interest is reported mid-month and end-of-month; short volume is daily.
