What is a straddle on PEPG?

A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration.

Current PEPG snapshot

As of May 15, 2026, spot at $1.55, ATM IV 17.50%, IV rank 2.85%, expected move 5.02%. The straddle on PEPG 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 straddle structure on PEPG specifically: PEPG IV at 17.50% is on the cheap side of its 1-year range, which favors premium-buying structures like a PEPG straddle, with a market-implied 1-standard-deviation move of approximately 5.02% (roughly $0.08 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 PEPG expiries trade a higher absolute premium for lower per-day decay. Position sizing on PEPG should anchor to the underlying notional of $1.55 per share and to the trader's directional view on PEPG stock.

PEPG straddle setup

The PEPG straddle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With PEPG near $1.55, the first option leg uses a $1.55 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PEPG 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 PEPG shares for the stock leg in covered calls and collars).

Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit.

When traders use straddle on PEPG

Straddles on PEPG are pure-volatility plays that profit from large moves in either direction; traders typically buy PEPG straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.

PEPG thesis for this straddle

The market-implied 1-standard-deviation range for PEPG extends from approximately $1.47 on the downside to $1.63 on the upside. A PEPG long straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. Current PEPG IV rank near 2.85% 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 PEPG at 17.50%. As a Healthcare name, PEPG options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PEPG-specific events.

PEPG straddle positions are structurally neutral / high-volatility (long premium); 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. PEPG positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move PEPG alongside the broader basket even when PEPG-specific fundamentals are unchanged. Always rebuild the position from current PEPG chain quotes before placing a trade.

Frequently asked questions

What is a straddle on PEPG?
A straddle on PEPG is the straddle strategy applied to PEPG (stock). The strategy is structurally neutral / high-volatility (long premium): A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration. With PEPG stock trading near $1.55, the strikes shown on this page are snapped to the nearest listed PEPG chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
How are PEPG straddle max profit and max loss calculated?
Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit. For the PEPG straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 17.50%), 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 PEPG straddle?
The breakeven for the PEPG straddle 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 PEPG market-implied 1-standard-deviation expected move is approximately 5.02%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
