Current SABS snapshot

As of May 15, 2026, spot at $3.67, ATM IV 176.30%, expected move 50.54%. The bull call spread on SABS 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 SABS specifically: IV rank is unavailable in the current snapshot, so regime-based timing for SABS is inferred from ATM IV at 176.30% alone, with a market-implied 1-standard-deviation move of approximately 50.54% (roughly $1.85 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 SABS expiries trade a higher absolute premium for lower per-day decay. Position sizing on SABS should anchor to the underlying notional of $3.67 per share and to the trader's directional view on SABS stock.

SABS bull call spread setup

The SABS 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 SABS near $3.67, the first option leg uses a $3.67 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SABS 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 SABS shares for the stock leg in covered calls and collars).

SABS thesis for this bull call spread

The market-implied 1-standard-deviation range for SABS extends from approximately $1.82 on the downside to $5.52 on the upside. A SABS bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on SABS, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. As a Healthcare name, SABS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SABS-specific events.

SABS 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. SABS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SABS alongside the broader basket even when SABS-specific fundamentals are unchanged. Long-premium structures like a bull call spread on SABS 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 SABS chain quotes before placing a trade.
