Moves with. Long Treasuries (21% of its variance, beta 0.06). These factors explain 20% of its daily moves over the last year, so most of what drives this fund is something else.

Stated objective. The Fund seeks as high a level of current income exempt from federal income tax as is consistent with relative stability of principal. (from the fund's prospectus)

Technical Indicators

Quick-reference for reading the values below. Indicators combine to confirm a view — no single one is a trade signal on its own.

Trend Indicators
  • 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.
Momentum Oscillators
  • 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.

Volume & Volatility
  • 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 →

JMST Stock Analysis Report

JPMorgan Ultra-Short Municipal Income ETF

Executive Summary

Overall Assessment: NEUTRAL | Confidence Level: 7/10

JMST is a large, actively managed ultra-short municipal bond ETF ($8.0B in assets) positioned as a cash-equivalent fixed income vehicle with modest yield enhancement. The fund is experiencing strong inflows (+$2.6B or 40.5% over 12 months, +$168M in latest month [SEC filing, reported through 2026-05]), reflecting investor demand for tax-advantaged short-duration income in a higher-rate environment.

Investment Thesis: JMST offers stability comparable to money market funds (beta 0.01, volatility 0.01, HV30 1.0%) while delivering a 2.56% trailing yield through a diversified portfolio of 1,963 short-maturity municipal bonds. The fund's technical picture shows a tight consolidation near all key moving averages, with neutral-to-slightly-bearish momentum but low absolute risk. Current positioning is appropriate for risk-averse income investors seeking tax efficiency rather than capital appreciation.

Recent News Sentiment Impact: The three available recent headlines (all NEUTRAL sentiment) reflect routine fund commentary and performance review rather than catalytic news. The April 2024 mention of hitting a 52-week high predates current price action and provides no directional signal.

Technical Analysis

Trend Direction

| Timeframe | Assessment | Evidence | |-----------|-----------|----------| | Short-term (1-4 weeks) | Consolidation/Neutral | Price $50.73 trades within $0.29 band around 20-day SMA ($50.62); no clear directional bias | | Medium-term (1-3 months) | Stable/Sideways | All three moving averages (SMA 20/50/200) clustered within $0.30 ($50.62–$50.92); suggests range-bound consolidation | | Long-term (3-12 months) | Stable Uptrend | Price above 200-day SMA ($50.92 vs $50.73 current = -0.19 or -0.37% below); fund has hit 52-week highs recently, indicating gradual appreciation |

Support/Resistance Levels

  • Immediate Support: $50.48 (Bollinger Band lower; represents -0.49% downside)
  • Primary Support: $50.62 (20-day SMA; critical pivot)
  • Secondary Support: $50.77 (50-day SMA; strong zone)
  • Resistance (Upside): $50.77 (upper Bollinger Band = current upper limit of trading range)
  • Psychological Level: $50.92 (200-day SMA; represents 12-month trend anchor)

Interpretation: Extremely tight technical structure with only $0.29 (57 basis points) between upper and lower Bollinger Bands indicates low volatility regime and low urgency for directional breakout.

Momentum Signals

| Indicator | Reading | Interpretation | |-----------|---------|-----------------| | RSI (14) | 57.97 | Neutral zone (neither overbought >70 nor oversold <30); no extremes indicating reversal pressure | | Stochastic %K/%D | 88.31 / 85.38 | Overbought in absolute terms, but with low historical volatility context, this reflects strong positioning within a narrow range rather than extreme momentum | | Williams %R | -12.90 | Neutral-to-slightly-bullish; near mid-range rather than extreme | | MACD | -0.02 / Signal 0.03 / Histogram: -0.05 | Bearish crossover signal: MACD (-0.02) has crossed below its signal line (0.03), with negative histogram (-0.05); suggests early bearish momentum divergence | | Bollinger Bands | Upper $50.77 / Middle $50.62 / Lower $50.48 | Price clustered near upper band; squeeze pattern (width 0.57) indicates consolidation ending; breakout likely imminent but direction unclear |

Momentum Summary: Mixed signals. Stochastic extremes and price near upper Bollinger Band suggest short-term overbought conditions within the consolidation, while MACD's recent bearish crossover indicates momentum loss. RSI neutrality suggests no capitulation or extreme greed.

Volume Analysis

  • Volume SMA 20: 2,012,725 shares (baseline)
  • Volume Rate of Change: +84.85% (volume elevated relative to 20-day average)
  • On-Balance Volume: 93,169,577 (cumulative positive volume suggests net buying pressure has been present)
  • Interpretation: Volume spike of +84.85% indicates institutional interest and heightened trading activity, consistent with the strong fund inflows documented in SEC filings. OBV remains positive, supporting continued demand, though volume elevation may reflect ETF creation/redemption activity typical for large index/passive vehicles rather than speculative trading.

News & Sentiment Analysis

Recent Headlines Summary

| Date | Headline | Sentiment | Relevance | |------|----------|-----------|-----------| | 2024-06-28 | Total Return Gov/Credit Q2 Review | NEUTRAL | Routine quarterly fund review; no specific JMST-related developments | | 2024-04-24 | JMST Hits 52-Week High | NEUTRAL | Historical news; price has since consolidated (current $50.73 likely near that level); confirms fund's uptrend | | 2024-03-25 | 2 ETFs to Buy (Cash-Like, Better Returns) | NEUTRAL | Generalized positive recommendation; highlights fund's value proposition vs money markets | | 2023-10-03 | Headwinds of Higher Yields (Muni Review) | NEUTRAL | Dated; reflects 2023 yield environment; context may have shifted in 18+ months |

Sentiment Assessment

Aggregate Sentiment: NEUTRAL (0 positive, 0 negative, 4 neutral headlines)

The lack of positive or negative catalysts in recent headlines is consistent with JMST's profile as a stable, low-volatility fund. Municipal bond ETFs rarely generate dramatic news unless there are:

  • Credit crises in underlying issuers
  • Major regulatory changes to muni markets
  • Tax law shifts affecting municipal bond demand
  • Significant fund closure or restructuring

None of these appear present for JMST.

Catalyst Identification

Immediate (1-7 days): None identified; no earnings, distributions, or events scheduled in available data.

Near-term (1-4 weeks):

  • Monthly/Quarterly Distribution Dates: Standard for bond ETFs; typically announce ex-dividend dates (not provided in data).
  • Fed Policy Signals: Interest rate expectations will drive municipal bond valuations; any hawkish/dovish signals could trigger repositioning.

Medium-term (1-3 months):

  • Tax Year-End (Q4 2026): Tax-loss harvesting in November-December may create redemption pressure (or buying by tax-loss harvesters rotating into similar funds).
  • Fiscal Year Planning: Corporate/institutional capital allocation decisions typically cycle quarterly.

Structural Catalysts:

  • Muni Market Stress: Any credit deterioration in top holdings (NY, Washington State, Maryland, Minnesota, Alaska Housing Finance—all represented in top 10) could trigger redemptions.
  • Yield Curve Normalization: Sharp flattening/steepening would reprrice ultra-short duration bonds.

Market Narrative

Alignment Analysis:

  • Technical Signals: Consolidation, neutral momentum, Bollinger Band squeeze suggest market at a transition point—potential breakout either direction.
  • News Narrative: Silence on negative developments; positive inflow data suggests sustained investor confidence in the fund's utility as a yield-enhanced cash alternative.
  • Conflict: MACD's bearish crossover contradicts the OBV accumulation and strong fund inflows, suggesting institutional buying (inflows) has cooled momentum slightly but conviction remains.

Overall Narrative: JMST is a "boring but steady" fund experiencing cyclical consolidation after strong 12-month inflow period. Neutral headlines and lack of catalysts suggest "steady as she goes" positioning for a municipal bond ETF designed to be a cash replacement rather than a trading vehicle.

Full Algorithm Docs ↗

Each spread is ranked by a composite score built in three stages. Full documentation →

Stage 1 — Base Score (GPU scanner)

score = P(profit) × (credit / spread_width)
P(profit) from short leg delta (1 − |delta|), penalised above 85%. Credit uses mid-price to handle illiquid chains fairly.

Stage 2 — Skew Adjustment (±25% cap)

RR and BF (30-delta) from the persisted per-symbol skew snapshot — wing strikes picked by real greeks.delta, not a moneyness proxy. Put skew boosts bull puts, penalises bear calls. High butterfly boosts iron condors. Calendars are skew-neutral.

Stage 3 — Technical Overlay (±50% cap, 5 groups)
Group 1 · Directional Bias (±0.25)
  • RSI <40 bullish / >60 bearish
  • MACD crossover + histogram trend
  • Price vs SMA 50 & SMA 200
Group 2 · Momentum (±0.10)
  • Stochastic %K <20 / >80
  • Williams %R <−80 / >−20
Group 3 · Volatility (up to −0.25 / +0.15)
  • Blended ATR + straddle expected-move penalty
  • Bollinger Band signal (+ counter-trend penalty)
  • BB width — vol contraction boost for ICs
Group 4 · IV Regime (±0.15)
  • IV rank ≥ 75 → strong boost for credit spreads
  • IV rank < 25 → penalty (selling cheap vol)
Group 5 · Liquidity (penalty up to −0.10)
  • Min open interest across all legs
  • OI < 100 → −0.10 · OI < 500 → −0.05

score = base_score × skew_multiplier × tech_multiplier

Skew (Wing IV − ATM IV)
DTE:
Wing Δ:
Metric:
Wing vs ATM
IV(put wing) − IV(ATM), in vol points

How 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.
Risk Reversal
IV(call wing) − IV(put wing), equal delta on each side

Which 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.
Reading them together

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.

JMST Institutional Ownership (13F)

Latest filings — 2026-09-30

Institutional managers with $100M+ AUM file Form 13F-HR quarterly, due 45 days after quarter end. Holdings are reported gross at quarter-end market value — they are a snapshot, not a real-time position.

  • Shares — long equity positions in this name, aggregated across share classes.
  • Calls / Puts — notional value of long call / put exposure where this ticker is the underlying.
  • % of Float — holder's reported shares divided by the latest diluted shares outstanding. Sums above 100% indicate large custodian / prime broker positions where the same shares are reported by multiple filers.
  • Custodian badge — filers with more than 5,000 holdings are typically broker-dealers / custodians reporting customer-held shares, not active managers.

Each filer is counted once at its latest 13F-HR filing. New filings are ingested on a weekly cadence.

Short Interest & Float

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.

Metric definitions
  • 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.
How to read the signals
  • 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.
History chart
  • 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.
