Current MIRM snapshot

As of May 15, 2026, spot at $103.34, ATM IV 44.50%, IV rank 23.05%, expected move 12.76%. The cash-secured put on MIRM 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 cash-secured put structure on MIRM specifically: MIRM IV at 44.50% is on the cheap side of its 1-year range, which means a premium-selling MIRM cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 12.76% (roughly $13.18 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 MIRM expiries trade a higher absolute premium for lower per-day decay. Position sizing on MIRM should anchor to the underlying notional of $103.34 per share and to the trader's directional view on MIRM stock.

MIRM cash-secured put setup

The MIRM cash-secured put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With MIRM near $103.34, the first option leg uses a $100.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MIRM 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 MIRM shares for the stock leg in covered calls and collars).

MIRM thesis for this cash-secured put

The market-implied 1-standard-deviation range for MIRM extends from approximately $90.16 on the downside to $116.52 on the upside. A MIRM cash-secured put lets a trader earn premium while waiting to acquire MIRM at the strike price; the strategy is most attractive when the trader is comfortable holding the underlying at that level and IV is rich enough to compensate for the assignment risk. Current MIRM IV rank near 23.05% 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 MIRM at 44.50%. As a Healthcare name, MIRM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MIRM-specific events.

MIRM cash-secured put positions are structurally neutral to slightly 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. MIRM positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MIRM alongside the broader basket even when MIRM-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on MIRM carry tail risk when realized volatility exceeds the implied move; review historical MIRM earnings reactions and macro stress periods before sizing. Always rebuild the position from current MIRM chain quotes before placing a trade.
