What is a butterfly on PRLD?
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 PRLD snapshot
As of May 14, 2026, spot at $4.48, ATM IV 143.00%, IV rank 28.66%, expected move 41.00%. The butterfly on PRLD 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 PRLD specifically: PRLD IV at 143.00% is on the cheap side of its 1-year range, which favors premium-buying structures like a PRLD butterfly, with a market-implied 1-standard-deviation move of approximately 41.00% (roughly $1.84 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 PRLD expiries trade a higher absolute premium for lower per-day decay. Position sizing on PRLD should anchor to the underlying notional of $4.48 per share and to the trader's directional view on PRLD stock.
PRLD butterfly setup
The PRLD 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 PRLD near $4.48, the first option leg uses a $4.26 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PRLD 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 PRLD shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $4.26 | N/A |
| Sell 2 | Call | $4.48 | N/A |
| Buy 1 | Call | $4.70 | N/A |

When traders use butterfly on PRLD
Butterflies on PRLD are pinning bets - traders use them when they expect PRLD 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.
PRLD thesis for this butterfly
The market-implied 1-standard-deviation range for PRLD extends from approximately $2.64 on the downside to $6.32 on the upside. A PRLD long call butterfly is a pinning play: it pays maximum at the middle strike if PRLD settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current PRLD IV rank near 28.66% 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 PRLD at 143.00%. As a Healthcare name, PRLD options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PRLD-specific events.
PRLD 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. PRLD positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move PRLD alongside the broader basket even when PRLD-specific fundamentals are unchanged. Always rebuild the position from current PRLD chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on PRLD?
- A butterfly on PRLD is the butterfly strategy applied to PRLD (stock). 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 PRLD stock trading near $4.48, the strikes shown on this page are snapped to the nearest listed PRLD chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are PRLD 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 PRLD butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 143.00%), 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 PRLD butterfly?
- The breakeven for the PRLD 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 PRLD market-implied 1-standard-deviation expected move is approximately 41.00%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
