RAPP snapshot
As of August 14, 2026, spot at $47.29, ATM IV 74.60%, IV rank 14.86%, expected move 21.39%. The bull call spread on RAPP 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 98-day expiry.
Why this bull call spread structure on RAPP specifically: RAPP IV at 74.60% is on the cheap side of its 1-year range, which favors premium-buying structures like a RAPP bull call spread, with a market-implied 1-standard-deviation move of approximately 21.39% (roughly $10.11 on the underlying). The 98-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated RAPP expiries trade a higher absolute premium for lower per-day decay. Position sizing on RAPP should anchor to the underlying notional of $47.29 per share and to the trader's directional view on RAPP stock.
RAPP bull call spread setup
The RAPP bull call spread 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 RAPP at $47.29 on that close, the first option leg uses a $47.50 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed RAPP chain at a 98-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 RAPP shares for the stock leg in covered calls and collars).

RAPP thesis for this bull call spread
The market-implied 1-standard-deviation range for RAPP extends from approximately $37.18 on the downside to $57.40 on the upside. A RAPP bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on RAPP, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current RAPP IV rank near 14.86% 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 RAPP at 74.60%. As a Healthcare name, RAPP options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to RAPP-specific events.
RAPP 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. RAPP positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move RAPP alongside the broader basket even when RAPP-specific fundamentals are unchanged. Long-premium structures like a bull call spread on RAPP 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 RAPP chain quotes before placing a trade.
