CGEM snapshot
As of November 13, 2026, spot at $10.20, ATM IV 93.90%, IV rank 17.54%, expected move 26.92%. The cash-secured put on CGEM below is built from the November 13, 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 cash-secured put structure on CGEM specifically: CGEM IV at 93.90% is on the cheap side of its 1-year range, which means a premium-selling CGEM cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 26.92% (roughly $2.75 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 CGEM expiries trade a higher absolute premium for lower per-day decay. Position sizing on CGEM should anchor to the underlying notional of $10.20 per share and to the trader's directional view on CGEM stock.
CGEM cash-secured put setup
The CGEM cash-secured put below is built from the November 13, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With CGEM at $10.20 on that close, the first option leg uses a $10.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CGEM 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 CGEM shares for the stock leg in covered calls and collars).

Cash-secured puts on CGEM earn premium while a trader waits to acquire CGEM stock at a target strike below the current quote; most attractive when IV is rich and the trader is comfortable owning CGEM.
CGEM thesis for this cash-secured put
The market-implied 1-standard-deviation range for CGEM extends from approximately $7.45 on the downside to $12.95 on the upside. A CGEM cash-secured put lets a trader earn premium while waiting to acquire CGEM 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 CGEM IV rank near 17.54% 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 CGEM at 93.90%. As a Healthcare name, CGEM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CGEM-specific events.
CGEM 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. CGEM positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CGEM alongside the broader basket even when CGEM-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on CGEM carry tail risk when realized volatility exceeds the implied move; review historical CGEM earnings reactions and macro stress periods before sizing. Always rebuild the position from current CGEM chain quotes before placing a trade.
