Current TNGX snapshot
As of June 30, 2026, spot at $31.27, ATM IV 61.40%, IV rank 0.00%, expected move 17.60%. The bear put spread on TNGX 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 17-day expiry.
Why this bear put spread structure on TNGX specifically: TNGX IV at 61.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a TNGX bear put spread, with a market-implied 1-standard-deviation move of approximately 17.60% (roughly $5.50 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated TNGX expiries trade a higher absolute premium for lower per-day decay. Position sizing on TNGX should anchor to the underlying notional of $31.27 per share and to the trader's directional view on TNGX stock.
TNGX bear put spread setup
The TNGX bear put spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With TNGX near $31.27, the first option leg uses a $31.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed TNGX chain at a 17-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 TNGX shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Put | $31.00 | $1.25 |
| Sell 1 | Put | $30.00 | $0.90 |

TNGX thesis for this bear put spread
The market-implied 1-standard-deviation range for TNGX extends from approximately $25.77 on the downside to $36.77 on the upside. A TNGX bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on TNGX, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current TNGX IV rank near 0.00% 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 TNGX at 61.40%. As a Healthcare name, TNGX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to TNGX-specific events.
TNGX bear put spread positions are structurally moderately bearish; 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. TNGX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move TNGX alongside the broader basket even when TNGX-specific fundamentals are unchanged. Long-premium structures like a bear put spread on TNGX are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current TNGX chain quotes before placing a trade.
