What is a butterfly on PRF?
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 PRF snapshot
As of May 14, 2026, spot at $52.80, ATM IV 25.50%, IV rank 29.89%, expected move 7.31%. The butterfly on PRF 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 35-day expiry.
Why this butterfly structure on PRF specifically: PRF IV at 25.50% is on the cheap side of its 1-year range, which favors premium-buying structures like a PRF butterfly, with a market-implied 1-standard-deviation move of approximately 7.31% (roughly $3.86 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated PRF expiries trade a higher absolute premium for lower per-day decay. Position sizing on PRF should anchor to the underlying notional of $52.80 per share and to the trader's directional view on PRF etf.
PRF butterfly setup
The PRF 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 PRF near $52.80, the first option leg uses a $50.16 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PRF chain at a 35-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 PRF shares for the stock leg in covered calls and collars).

|---|---|---|---|

| Sell 2 | Call | $52.80 | N/A |
| Buy 1 | Call | $55.44 | N/A |

Butterflies on PRF are pinning bets - traders use them when they expect PRF 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.
PRF thesis for this butterfly
The market-implied 1-standard-deviation range for PRF extends from approximately $48.94 on the downside to $56.66 on the upside. A PRF long call butterfly is a pinning play: it pays maximum at the middle strike if PRF settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current PRF IV rank near 29.89% 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 PRF at 25.50%. As a Financial Services name, PRF options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PRF-specific events.
PRF 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. PRF positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move PRF alongside the broader basket even when PRF-specific fundamentals are unchanged. Always rebuild the position from current PRF chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on PRF?
- A butterfly on PRF is the butterfly strategy applied to PRF (etf). The strategy is structurally neutral / pin (limited-risk, limited-reward): 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. With PRF etf trading near $52.80, the strikes shown on this page are snapped to the nearest listed PRF chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are PRF butterfly max profit and max loss calculated?
- Max profit equals the wing width minus net debit times 100 (reached when the underlying pins the middle strike); max loss equals the net debit times 100. Two breakevens at lower-wing plus debit and upper-wing minus debit. For the PRF butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 25.50%), the computed maximum profit is unbounded per contract and the computed maximum loss is unbounded per contract. Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a PRF butterfly?
- The breakeven for the PRF butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current PRF market-implied 1-standard-deviation expected move is approximately 7.31%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
