MULL snapshot

As of August 14, 2026, spot at $22.45, ATM IV 129.30%, IV rank 32.66%, expected move 37.07%. The bull call spread on MULL 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 bull call spread structure on MULL specifically: MULL IV at 129.30% 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 37.07% (roughly $8.32 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 MULL expiries trade a higher absolute premium for lower per-day decay. Position sizing on MULL should anchor to the underlying notional of $22.45 per share and to the trader's directional view on MULL etf.

MULL bull call spread setup

The MULL bull call spread 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 MULL at $22.45 on that close, the first option leg uses a $22.40 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MULL 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 MULL shares for the stock leg in covered calls and collars).

MULL thesis for this bull call spread

The market-implied 1-standard-deviation range for MULL extends from approximately $14.13 on the downside to $30.77 on the upside. A MULL bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on MULL, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current MULL IV rank near 32.66% is mid-range against its 1-year distribution, so the IV signal is neutral; the bull call spread thesis on MULL should anchor more to the directional view and the expected-move geometry. As a Financial Services name, MULL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MULL-specific events.

MULL bull call spread positions are structurally moderately bullish; 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. MULL positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MULL alongside the broader basket even when MULL-specific fundamentals are unchanged. Long-premium structures like a bull call spread on MULL 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 MULL chain quotes before placing a trade.
