Current TNDM snapshot
As of June 29, 2026, spot at $15.71, ATM IV 76.00%, IV rank 22.12%, expected move 21.79%. The iron condor on TNDM 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 18-day expiry.
Why this iron condor structure on TNDM specifically: TNDM IV at 76.00% is on the cheap side of its 1-year range, which means a premium-selling TNDM iron condor collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 21.79% (roughly $3.42 on the underlying). The 18-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated TNDM expiries trade a higher absolute premium for lower per-day decay. Position sizing on TNDM should anchor to the underlying notional of $15.71 per share and to the trader's directional view on TNDM stock.
TNDM iron condor setup
The TNDM iron condor below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With TNDM near $15.71, the first option leg uses a $16.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed TNDM chain at a 18-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 TNDM shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Sell 1 | Call | $16.00 | $1.10 |
| Buy 1 | Call | $17.00 | $0.70 |
| Sell 1 | Put | $15.00 | $0.60 |

TNDM thesis for this iron condor
The market-implied 1-standard-deviation range for TNDM extends from approximately $12.29 on the downside to $19.13 on the upside. A TNDM iron condor is a delta-neutral premium-collection structure that pays off when TNDM stays inside the inner short strikes through expiration; the wing width should reflect the trader's tolerance for the maximum loss scenario where the underlying breaches an outer strike. Current TNDM IV rank near 22.12% 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 TNDM at 76.00%. As a Healthcare name, TNDM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to TNDM-specific events.
TNDM iron condor positions are structurally neutral / range-bound; 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. TNDM positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move TNDM alongside the broader basket even when TNDM-specific fundamentals are unchanged. Short-premium structures like a iron condor on TNDM carry tail risk when realized volatility exceeds the implied move; review historical TNDM earnings reactions and macro stress periods before sizing. Always rebuild the position from current TNDM chain quotes before placing a trade.
