TNGX snapshot

As of August 14, 2026, spot at $25.40, ATM IV 81.90%, IV rank 16.13%, expected move 23.48%. The covered call on TNGX below is built from the August 14, 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 covered call structure on TNGX specifically: TNGX IV at 81.90% is on the cheap side of its 1-year range, which means a premium-selling TNGX covered call collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 23.48% (roughly $5.96 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 TNGX expiries trade a higher absolute premium for lower per-day decay. Position sizing on TNGX should anchor to the underlying notional of $25.40 per share and to the trader's directional view on TNGX stock.

TNGX covered call setup

The TNGX covered call below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With TNGX at $25.40 on that close, the first option leg uses a $27.00 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 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 TNGX shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 100 shares	Stock	$25.40	long
Sell 1	Call	$27.00	$1.78

When traders use covered call on TNGX

Covered calls on TNGX are an income strategy run on existing TNGX stock positions; traders typically sell calls at 25-35 delta with 30-45 days to expiration to balance premium against upside cap.

TNGX thesis for this covered call

The market-implied 1-standard-deviation range for TNGX extends from approximately $19.44 on the downside to $31.36 on the upside. A TNGX covered call collects premium on an existing long TNGX position, trading off upside above the short call strike for immediate income; the short strike selection should reflect the trader's view on whether TNGX will breach that level within the expiration window. Current TNGX IV rank near 16.13% 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 81.90%. 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 covered call 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. 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. Short-premium structures like a covered call on TNGX carry tail risk when realized volatility exceeds the implied move; review historical TNGX earnings reactions and macro stress periods before sizing. Always rebuild the position from current TNGX chain quotes before placing a trade.
