A cash-secured put sells an out-of-the-money put while holding cash equal to the strike-times-100 obligation, keeping the premium when the underlying stays above the strike.

MGNX snapshot

As of August 14, 2026, spot at $4.05, ATM IV 93.20%, IV rank 17.23%, expected move 26.72%. The cash-secured put on MGNX below is built from the 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 cash-secured put structure on MGNX specifically: MGNX IV at 93.20% is on the cheap side of its 1-year range, which means a premium-selling MGNX cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 26.72% (roughly $1.08 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 MGNX expiries trade a higher absolute premium for lower per-day decay. Position sizing on MGNX should anchor to the underlying notional of $4.05 per share and to the trader's directional view on MGNX stock.

MGNX cash-secured put setup

The MGNX 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 MGNX at $4.05 on that close, the first option leg uses a $3.85 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MGNX 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 MGNX shares for the stock leg in covered calls and collars).

MGNX thesis for this cash-secured put

The market-implied 1-standard-deviation range for MGNX extends from approximately $2.97 on the downside to $5.13 on the upside. A MGNX cash-secured put lets a trader earn premium while waiting to acquire MGNX 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 MGNX IV rank near 17.23% 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 MGNX at 93.20%. As a Healthcare name, MGNX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MGNX-specific events.

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