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
ARKB (ARK 21Shares Bitcoin ETF) - Comprehensive Analysis Report
Executive Summary
Overall Assessment: NEUTRAL with 6/10 Confidence
ARKB presents a conflicted technical and sentiment picture within a high-volatility, actively managed Bitcoin ETF framework. The fund benefits from strong recent inflows (+$196M in September 2026, +6.2% of assets over 3 months) and positive crypto sentiment headlines, but technical momentum shows emerging weakness despite bullish MACD signals. The high beta (1.77) and elevated volatility (36-37% HV) create significant directional risk, while the put/call volume ratio (2.66) signals defensive positioning by options traders ahead of potential consolidation.
Investment Thesis: ARKB is capturing strong institutional and retail interest in Bitcoin exposure through an actively managed vehicle, but the fund faces a technical inflection point where overbought conditions (RSI neutral at 51, but Stochastic %K at 32.89 suggesting recent pullback), negative fund flows in volume metrics (-34.82% volume ROC), and bearish options positioning could precede a consolidation phase. The asymmetric put/call volume ratio indicates options traders expect downside volatility over the next 1-4 weeks.
Recent News Sentiment Impact: News flow is moderately POSITIVE overall (4 positive, 1 negative, 1 neutral since June 2026), focusing on Bitcoin ETF inflows and crypto market revival. However, the June 2026 SpaceX IPO headline suggests potential capital rotation away from crypto, which may explain the recent volume decline and put accumulation despite positive news.
Technical Analysis
Trend Direction
| Timeframe | Direction | Confidence | Interpretation | |---|---|---|---| | Short-term (1-4 weeks) | CONSOLIDATION → Potential Breakdown | Medium | Price trading between SMA20 ($27.67) and SMA50 ($25.59), recent close at $27.09 suggests weakening momentum | | Medium-term (1-3 months) | UPTREND (intact but losing steam) | Medium-High | Price above all major MAs; however, negative volume ROC and put accumulation suggest traders hedging upside | | Long-term (3-12 months) | UPTREND | High | Price $27.09 well above SMA200 ($24.49; +10.6%); strong fund inflows support structural bid |
Support/Resistance Levels
| Level | Type | Distance | Significance | |---|---|---|---| | $29.09 | Resistance (Bollinger Upper Band) | +$1.99 (+7.3%) | Immediate overhead; short-term overbought zone | | $27.67 | Dynamic Support (SMA 20) | -$0.58 (-2.1%) | Near-term technical floor; 20-day trend anchor | | $26.24 | Support (Bollinger Lower Band) | -$0.85 (-3.1%) | Mean-reversion target if consolidation fails | | $25.59 | Strong Support (SMA 50) | -$1.50 (-5.5%) | Medium-term support; major moving average | | $24.49 | Strong Support (SMA 200) | -$2.60 (-9.6%) | Long-term trend line; major technical floor |
Momentum Signals
MACD (Bullish):
- MACD Line: 0.47 | Signal Line: -0.23 | Histogram: +0.69 (BULLISH DIVERGENCE)
- Interpretation: MACD above signal line with positive histogram indicates bullish momentum initiation, but the negative signal line suggests momentum may be building from a recent low. This is a future-looking bullish signal, not confirmation of current strength.
- Signal Quality: MODERATE — Histogram positive but signal line still underwater suggests early-stage recovery, not sustained momentum.
RSI (14): 51.10 (NEUTRAL)
- Interpretation: Squarely in neutral zone (30-70), indicating neither overbought nor oversold conditions. Recent Stochastic %K at 32.89 and %D at 32.36 suggest oscillators just turned upward from oversold territory, consistent with early-stage recovery.
- Signal Quality: MODERATE — RSI neutrality suggests price consolidation phase; no compelling directional conviction from momentum yet.
Williams %R: -79.39 (OVERSOLD)
- Interpretation: Deeply oversold, indicating potential mean-reversion bounce. This contradicts the neutral RSI and suggests intraday volatility rather than directional exhaustion.
- Signal Quality: LOW — Williams %R may be exaggerated on lower timeframes; conflicting with RSI suggests mixed momentum.
Bollinger Bands (NEUTRAL):
- Width: 10.30% (mid-range volatility, neither squeeze nor extreme expansion)
- Position: Price $27.09 trading between middle band ($27.67) and lower band ($26.24)
- Signal: Neither mean-reversion pressure nor breakout conditions present; band width suggests consolidation environment.
Volume Analysis
Critical Volume Weakness Detected:
- Volume SMA 20: 1,390,813 shares (baseline)
- Volume Rate of Change: -34.82% (SIGNIFICANT DECLINE)
- On-Balance Volume (OBV): -127.2M (deeply negative; cumulative selling pressure)
Interpretation: Despite positive news and fund inflows (flows are assets not volume), the sharp 34.82% decline in trading volume combined with deeply negative OBV indicates:
- Institutional inflows are NOT translating to aggressive buying volume — flows likely reflect passive/automated purchases into the fund
- Net selling pressure from active traders — negative OBV suggests cumulative distribution
- Potential late-stage rally fatigue — strong uptrends supported by volume; this rally lacks conviction
Institutional Interest Signal: CAUTIONARY — Fund inflows (+6.2% YTD) are significant, but volume patterns suggest passive index/allocation flows, not active accumulation at higher prices. This is typical of successful ETFs attracting capital, but volume weakness often precedes consolidation or pullback.
News & Sentiment Analysis
Recent Headlines Summary
| Date | Source | Theme | Sentiment | Relevance to ARKB | |---|---|---|---|---| | 2026-09-23 | GlobeNewswire | Bitcoin ETF inflows ($998.95M) + crypto presale hype | POSITIVE | Direct catalyst for fund inflows; validates Bitcoin ETF demand | | 2026-09-11 | Motley Fool | Cathie Wood crypto forecast (+1,490% potential) | NEUTRAL | Supportive of ARK's crypto thesis, but generic prediction | | 2026-08-27 | Zacks | Bitcoin ETF revival post-downturn | POSITIVE | Macroeconomic tailwind for Bitcoin demand | | 2026-06-10 | Benzinga | SpaceX IPO potential capital rotation away from crypto | NEGATIVE | This headline aligns with volume decline and put accumulation | | 2025-09-06 | Motley Fool | Retail crypto investment guidance | POSITIVE | Broad-market retail interest; supports long-term demand | | 2025-07-12 | Motley Fool | 5-year Bitcoin ETF outlook | POSITIVE | Institutional confidence in Bitcoin ETF category |
Sentiment Assessment
Aggregate Sentiment: MODERATELY POSITIVE (4 positive, 1 negative, 1 neutral)
However, news sentiment diverges sharply from recent price action and volume data:
- Positive news flow (latest articles from Sept 2026) suggests Bitcoin ETF inflows should accelerate
- Actual volume metrics (down 34.82%) and put/call ratios (2.66 puts per call) indicate traders are bracing for consolidation despite positive headlines
- Catalyst mismatch: The most recent positive news (Bitcoin ETF inflows, Sept 2026) should be driving volume, but instead volume has collapsed
Interpretation: Market may be price-discounting the Bitcoin narrative already (fund already up 10.6% since 200-day MA), and retail/retail-focused headlines ("$100 investment," "Smartest way to invest") suggest retail euphoria. Historically, retail-focused positive news coupled with declining volume can precede localized pullbacks

Estimated net dealer gamma is at the 61st percentile of this name's own daily history, within its typical 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.

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.
