What is the JMST 30-day expected price range?

As of Jul 15, 2026, with JMST at $50.92 and ATM IV at 13.0%, the implied 30-day one-standard-deviation range is approximately ±$1.90, or about $49.02 to $52.82. IV rank is subdued, so the priced distribution is tighter than the 1-year typical width.

What does JMST risk-neutral density tell us?

Risk-neutral density is the probability distribution of future JMST price implied by listed option prices. Extracted via Breeden-Litzenberger (twice-differentiating the call price function with respect to strike), it represents the pricing kernel rather than the real-world probability of outcomes. Persistent skew or fat-tail features in the density reflect how the market is pricing tail risk.

How does JMST ATM IV translate to a probability range?

ATM IV is annualized; multiplying by sqrt(t/365) scales it to the chosen tenor. Under lognormal assumptions, the resulting standard deviation defines the ±1σ band that contains roughly 68% of outcomes, ±2σ for 95%. Empirical equity returns have fatter tails than log-normal, so the implied tail probabilities under-state realized tail frequency in stressed regimes.

Snapshot as of Jul 15, 2026.

Spot Price: $50.92
ATM IV: 13.0%
IV Rank: 2.6%
IV Percentile: 67.9%
HV 20-Day: 0.8%
IV Skew 25Δ: 0.004

As of Jul 15, 2026, JPMorgan Ultra-Short Municipal Income ETF (JMST) at $50.92 has an ATM IV of 13.0%, implying a 30-day one-standard-deviation range of approximately ±$1.90. IV rank is 2.6% (subdued, distribution priced tighter than usual). IV percentile is 67.9%. The 25-delta skew is +0.004: roughly symmetric wings. Under lognormal assumptions roughly 68% of outcomes fall within ±1σ and 95% within ±2σ; risk-neutral probability analysis refines this by extracting the market-implied distribution directly from options prices, capturing the fat tails that real markets exhibit.

How JMST probability analysis Data Feeds Strategy Selection

Strategy selection on JPMorgan Ultra-Short Municipal Income ETF options does not derive from any single metric in isolation. The probability analysis view above sits inside a broader read: ATM IV currently sits at 13.0% and dealer gamma exposure is negative, so dealer hedging amplifies directional moves. Combine the probability analysis data here with the volatility-skew surface, dealer-gamma exposure, max-pain level, and upcoming-events calendar to build a positioning thesis. Risk-defined structures (credit spreads, debit spreads, iron condors) are usually safer than naked positions while the regime is uncertain; the data on this page anchors the inputs but does not by itself constitute a trade thesis.

How to read the JMST probability distribution

The probability cone above is the option-market-implied distribution of where JPMorgan Ultra-Short Municipal Income ETF spot could end up at expiration. It's derived from the implied-volatility surface via a risk-neutral pricing transformation, not from historical realized returns. With ATM IV at 13.0% and spot at $50.92, the 1σ band is approximately ±4.5% over a 30-day horizon. Recent realized HV-20 of 0.8% runs 12.2 vol points below the current implied, suggesting the chain is pricing more dispersion than the underlying has been delivering.

JMST risk-neutral vs real-world probabilities

The probabilities derived from option prices reflect the market's risk-adjusted view, not the realized statistical distribution. Risk-neutral probabilities include the equity risk premium and skew preferences priced into options, so they tend to overstate tail probability and understate upside drift relative to actually-realized outcomes. For probability-of-touch calculations and assignment-risk modeling, risk-neutral is the right benchmark. For position-sizing your own conviction, blend with realized-volatility-based statistics from the HV columns.

Trading the JMST distribution

Probability-driven strategies aim to capture mispricings between the implied distribution and your own probability assessment. Premium-selling structures (credit spreads, iron condors, cash-secured puts) profit when the implied distribution overprices tail probability relative to realized; premium-buying (debit spreads, long calls/puts, long straddles) profits in the reverse. With JMST IV rank at 2.6%, the chain is pricing tighter tails than recent realized history; buyers get cheaper optionality but need a real catalyst to monetize. Always pair probability-driven strategy selection with a stop loss or wing-defined risk - the implied distribution is a snapshot, and regime shifts can invalidate it intraday.
