Current TENX snapshot
As of May 15, 2026, spot at $11.77, ATM IV 87.40%, expected move 25.06%. The bull call spread on TENX 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 34-day expiry.
Why this bull call spread structure on TENX specifically: IV rank is unavailable in the current snapshot, so regime-based timing for TENX is inferred from ATM IV at 87.40% alone, with a market-implied 1-standard-deviation move of approximately 25.06% (roughly $2.95 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated TENX expiries trade a higher absolute premium for lower per-day decay. Position sizing on TENX should anchor to the underlying notional of $11.77 per share and to the trader's directional view on TENX stock.
TENX bull call spread setup
The TENX bull call 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 TENX near $11.77, the first option leg uses a $11.77 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed TENX chain at a 34-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 TENX shares for the stock leg in covered calls and collars).

TENX thesis for this bull call spread
The market-implied 1-standard-deviation range for TENX extends from approximately $8.82 on the downside to $14.72 on the upside. A TENX bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on TENX, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. As a Healthcare name, TENX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to TENX-specific events.
TENX bull call spread positions are structurally moderately 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. TENX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move TENX alongside the broader basket even when TENX-specific fundamentals are unchanged. Long-premium structures like a bull call spread on TENX 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 TENX chain quotes before placing a trade.
