Current TENB snapshot
As of May 15, 2026, spot at $21.45, ATM IV 58.10%, IV rank 60.59%, expected move 16.66%. The bull call spread on TENB 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 TENB specifically: TENB IV at 58.10% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 16.66% (roughly $3.57 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 TENB expiries trade a higher absolute premium for lower per-day decay. Position sizing on TENB should anchor to the underlying notional of $21.45 per share and to the trader's directional view on TENB stock.
TENB bull call spread setup
The TENB 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 TENB near $21.45, the first option leg uses a $21.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed TENB 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 TENB shares for the stock leg in covered calls and collars).

A TENB bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on TENB, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current TENB IV rank near 60.59% is mid-range against its 1-year distribution, so the IV signal is neutral; the bull call spread thesis on TENB should anchor more to the directional view and the expected-move geometry. As a Technology name, TENB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to TENB-specific events.
TENB 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. TENB positions also carry Technology sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move TENB alongside the broader basket even when TENB-specific fundamentals are unchanged. Long-premium structures like a bull call spread on TENB 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 TENB chain quotes before placing a trade.
