What is a straddle on PRME?

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 PRME snapshot

As of June 26, 2026, spot at $3.25, ATM IV 70.00%, IV rank 16.66%, expected move 20.07%. The straddle on PRME 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 21-day expiry.

Why this straddle structure on PRME specifically: PRME IV at 70.00% is on the cheap side of its 1-year range, which favors premium-buying structures like a PRME straddle, with a market-implied 1-standard-deviation move of approximately 20.07% (roughly $0.65 on the underlying). The 21-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated PRME expiries trade a higher absolute premium for lower per-day decay. Position sizing on PRME should anchor to the underlying notional of $3.25 per share and to the trader's directional view on PRME stock.

PRME straddle setup

The PRME 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 PRME near $3.25, the first option leg uses a $3.25 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PRME chain at a 21-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 PRME shares for the stock leg in covered calls and collars).

PRME straddle risk and reward

Net Premium / Debit: N/A
Max Profit (per contract): Unbounded
Max Loss (per contract): Unbounded
Breakeven(s): None on modeled curve
Risk / Reward Ratio: N/A

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 PRME

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

PRME thesis for this straddle

The market-implied 1-standard-deviation range for PRME extends from approximately $2.60 on the downside to $3.90 on the upside. A PRME 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 PRME IV rank near 16.66% 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 PRME at 70.00%. As a Healthcare name, PRME options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PRME-specific events.

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