Current MIAX snapshot

As of June 30, 2026, spot at $36.90, ATM IV 59.10%, IV rank 7.34%, expected move 16.94%. The bear put spread on MIAX 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 17-day expiry.

Why this bear put spread structure on MIAX specifically: MIAX IV at 59.10% is on the cheap side of its 1-year range, which favors premium-buying structures like a MIAX bear put spread, with a market-implied 1-standard-deviation move of approximately 16.94% (roughly $6.25 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated MIAX expiries trade a higher absolute premium for lower per-day decay. Position sizing on MIAX should anchor to the underlying notional of $36.90 per share and to the trader's directional view on MIAX stock.

MIAX bear put spread setup

The MIAX bear put spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With MIAX near $36.90, the first option leg uses a $36.90 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MIAX chain at a 17-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 MIAX shares for the stock leg in covered calls and collars).

MIAX thesis for this bear put spread

The market-implied 1-standard-deviation range for MIAX extends from approximately $30.65 on the downside to $43.15 on the upside. A MIAX bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on MIAX, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current MIAX IV rank near 7.34% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on MIAX at 59.10%. As a Financial Services name, MIAX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MIAX-specific events.

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