MUB snapshot
As of August 14, 2026, spot at $105.90, ATM IV 293.20%, IV rank 61.47%, expected move 1.15%. The long put on MUB below is built from the August 14, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.
Why this long put structure on MUB specifically: MUB IV at 293.20% 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 1.15% (roughly $1.22 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated MUB expiries trade a higher absolute premium for lower per-day decay. Position sizing on MUB should anchor to the underlying notional of $105.90 per share and to the trader's directional view on MUB etf.
MUB long put setup
The MUB long put below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With MUB at $105.90 on that close, the first option leg uses a $106.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MUB chain at a 35-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 MUB shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |

MUB thesis for this long put
The market-implied 1-standard-deviation range for MUB extends from approximately $104.68 on the downside to $107.12 on the upside. A MUB long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long MUB position with one put per 100 shares held. Current MUB IV rank near 61.47% is mid-range against its 1-year distribution, so the IV signal is neutral; the long put thesis on MUB should anchor more to the directional view and the expected-move geometry. As a Financial Services name, MUB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MUB-specific events.
MUB long put positions are structurally bearish; 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. MUB positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MUB alongside the broader basket even when MUB-specific fundamentals are unchanged. Long-premium structures like a long put on MUB are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current MUB chain quotes before placing a trade.
