What is a long put on IONS?

Current IONS snapshot

As of June 29, 2026, spot at $80.94, ATM IV 39.60%, IV rank 3.94%, expected move 11.35%. The long put on IONS 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 18-day expiry.

Why this long put structure on IONS specifically: IONS IV at 39.60% is on the cheap side of its 1-year range, which favors premium-buying structures like a IONS long put, with a market-implied 1-standard-deviation move of approximately 11.35% (roughly $9.19 on the underlying). The 18-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated IONS expiries trade a higher absolute premium for lower per-day decay. Position sizing on IONS should anchor to the underlying notional of $80.94 per share and to the trader's directional view on IONS stock.

IONS long put setup

The IONS long put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With IONS near $80.94, the first option leg uses a $80.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed IONS chain at a 18-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 IONS shares for the stock leg in covered calls and collars).

When traders use long put on IONS

Long puts on IONS hedge an existing long IONS stock position or express a bearish view with defined risk; position sizing typically scales the put notional to the underlying IONS exposure being hedged.

IONS thesis for this long put

The market-implied 1-standard-deviation range for IONS extends from approximately $71.75 on the downside to $90.13 on the upside. A IONS long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long IONS position with one put per 100 shares held. Current IONS IV rank near 3.94% 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 IONS at 39.60%. As a Healthcare name, IONS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to IONS-specific events.

IONS long put positions are structurally bearish; 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. IONS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move IONS alongside the broader basket even when IONS-specific fundamentals are unchanged. Long-premium structures like a long put on IONS are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current IONS chain quotes before placing a trade.
