What is a straddle on IDYA?

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 IDYA snapshot

As of May 15, 2026, spot at $28.16, ATM IV 65.50%, IV rank 8.89%, expected move 18.78%. The straddle on IDYA 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 IDYA specifically: IDYA IV at 65.50% is on the cheap side of its 1-year range, which favors premium-buying structures like a IDYA straddle, with a market-implied 1-standard-deviation move of approximately 18.78% (roughly $5.29 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 IDYA expiries trade a higher absolute premium for lower per-day decay. Position sizing on IDYA should anchor to the underlying notional of $28.16 per share and to the trader's directional view on IDYA stock.

IDYA straddle setup

The IDYA 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 IDYA near $28.16, the first option leg uses a $28.16 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed IDYA 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 IDYA shares for the stock leg in covered calls and collars).

IDYA 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 IDYA

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

IDYA thesis for this straddle

The market-implied 1-standard-deviation range for IDYA extends from approximately $22.87 on the downside to $33.45 on the upside. A IDYA 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 IDYA IV rank near 8.89% 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 IDYA at 65.50%. As a Healthcare name, IDYA options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to IDYA-specific events.

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