RPRX (Royalty Pharma plc) trades in the Healthcare sector, specifically Biotechnology, with a market capitalization of approximately $22.90B, a trailing P/E of 27.79, a beta of 0.40 versus the broader market, a 52-week range of 32.15-53.29, average daily share volume of 3.3M, a public-listing history dating back to 2020, approximately 75 full-time employees. These structural characteristics shape how RPRX stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

What is a butterfly on RPRX?
A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration.
Current RPRX snapshot
As of May 15, 2026, spot at $52.75, ATM IV 30.50%, IV rank 16.35%, expected move 8.74%. The butterfly on RPRX 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 butterfly structure on RPRX specifically: RPRX IV at 30.50% is on the cheap side of its 1-year range, which favors premium-buying structures like a RPRX butterfly, with a market-implied 1-standard-deviation move of approximately 8.74% (roughly $4.61 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 RPRX expiries trade a higher absolute premium for lower per-day decay. Position sizing on RPRX should anchor to the underlying notional of $52.75 per share and to the trader's directional view on RPRX stock.
RPRX butterfly setup
The RPRX butterfly below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With RPRX near $52.75, the first option leg uses a $50.11 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed RPRX 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 RPRX shares for the stock leg in covered calls and collars).

When traders use butterfly on RPRX
Butterflies on RPRX are pinning bets - traders use them when they expect RPRX to settle near a specific level at expiration (often the prior close, a round number, or the max-pain strike) and want defined-risk exposure to that outcome.
RPRX thesis for this butterfly
The market-implied 1-standard-deviation range for RPRX extends from approximately $48.14 on the downside to $57.36 on the upside. A RPRX long call butterfly is a pinning play: it pays maximum at the middle strike if RPRX settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current RPRX IV rank near 16.35% 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 RPRX at 30.50%. As a Healthcare name, RPRX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to RPRX-specific events.
RPRX butterfly positions are structurally neutral / pin (limited-risk, limited-reward); 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. RPRX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move RPRX alongside the broader basket even when RPRX-specific fundamentals are unchanged. Always rebuild the position from current RPRX chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on RPRX?

With RPRX stock trading near $52.75, the strikes shown on this page are snapped to the nearest listed RPRX chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are RPRX butterfly max profit and max loss calculated?

Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current RPRX market-implied 1-standard-deviation expected move is approximately 8.74%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
