What is a straddle on JMSB?
A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration.
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 straddle 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 straddle 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 straddle setup
The JMSB straddle 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 $20.76 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).

When traders use straddle on JMSB

JMSB thesis for this straddle
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 straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. Current JMSB IV rank near 34.02% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle 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 straddle positions are structurally neutral / high-volatility (long premium); 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.
