What is a strangle on JMSB?
A long strangle buys an OTM call and an OTM put at offset strikes, cheaper than a straddle but requiring a larger underlying move to profit since both wings start out-of-the-money.
Current JMSB snapshot
As of May 15, 2026, spot at $20.76, ATM IV 71.50%, IV rank 34.02%, expected move 20.50%. The strangle on JMSB below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 34-day expiry.
Why this strangle structure on JMSB specifically: JMSB IV at 71.50% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 20.50% (roughly $4.26 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated JMSB expiries trade a higher absolute premium for lower per-day decay. Position sizing on JMSB should anchor to the underlying notional of $20.76 per share and to the trader's directional view on JMSB stock.
JMSB strangle setup
The JMSB strangle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With JMSB near $20.76, the first option leg uses a $21.80 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed JMSB chain at a 34-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 JMSB shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $21.80 | N/A |
| Buy 1 | Put | $19.72 | N/A |

JMSB thesis for this strangle
The market-implied 1-standard-deviation range for JMSB extends from approximately $16.50 on the downside to $25.02 on the upside. A JMSB long strangle is the OTM cousin of the straddle: lower up-front cost but the underlying has to travel further past either OTM strike before the position turns profitable at expiration. Current JMSB IV rank near 34.02% is mid-range against its 1-year distribution, so the IV signal is neutral; the strangle thesis on JMSB should anchor more to the directional view and the expected-move geometry. As a Financial Services name, JMSB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to JMSB-specific events.
JMSB strangle positions are structurally neutral / high-volatility (long premium, OTM); the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. JMSB positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move JMSB alongside the broader basket even when JMSB-specific fundamentals are unchanged. Always rebuild the position from current JMSB chain quotes before placing a trade.
