Current DXCM snapshot
As of May 15, 2026, spot at $61.55, ATM IV 40.94%, IV rank 25.17%, expected move 11.74%. The cash-secured put on DXCM 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 28-day expiry.
Why this cash-secured put structure on DXCM specifically: DXCM IV at 40.94% is on the cheap side of its 1-year range, which means a premium-selling DXCM cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 11.74% (roughly $7.22 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated DXCM expiries trade a higher absolute premium for lower per-day decay. Position sizing on DXCM should anchor to the underlying notional of $61.55 per share and to the trader's directional view on DXCM stock.
DXCM cash-secured put setup
The DXCM 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 DXCM near $61.55, the first option leg uses a $58.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed DXCM chain at a 28-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 DXCM shares for the stock leg in covered calls and collars).

DXCM thesis for this cash-secured put
The market-implied 1-standard-deviation range for DXCM extends from approximately $54.33 on the downside to $68.77 on the upside. A DXCM cash-secured put lets a trader earn premium while waiting to acquire DXCM 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 DXCM IV rank near 25.17% 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 DXCM at 40.94%. As a Healthcare name, DXCM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to DXCM-specific events.
DXCM 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. DXCM positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move DXCM alongside the broader basket even when DXCM-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on DXCM carry tail risk when realized volatility exceeds the implied move; review historical DXCM earnings reactions and macro stress periods before sizing. Always rebuild the position from current DXCM chain quotes before placing a trade.
