What is a long put on IMSR?
A long put buys downside exposure with a fixed maximum loss equal to the premium paid; profit accrues if the underlying closes below the strike minus premium at expiration.
IMSR snapshot
As of August 14, 2026, spot at $5.95, ATM IV 101.90%, IV rank 28.61%, expected move 29.21%. The long put on IMSR below is built from the 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 long put structure on IMSR specifically: IMSR IV at 101.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a IMSR long put, with a market-implied 1-standard-deviation move of approximately 29.21% (roughly $1.74 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 IMSR expiries trade a higher absolute premium for lower per-day decay. Position sizing on IMSR should anchor to the underlying notional of $5.95 per share and to the trader's directional view on IMSR stock.
IMSR long put setup
The IMSR 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 IMSR at $5.95 on that close, the first option leg uses a $5.95 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed IMSR 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 IMSR shares for the stock leg in covered calls and collars).

IMSR thesis for this long put
The market-implied 1-standard-deviation range for IMSR extends from approximately $4.21 on the downside to $7.69 on the upside. A IMSR long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long IMSR position with one put per 100 shares held. Current IMSR IV rank near 28.61% 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 IMSR at 101.90%. As a Utilities name, IMSR options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to IMSR-specific events.
IMSR 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. IMSR positions also carry Utilities sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move IMSR alongside the broader basket even when IMSR-specific fundamentals are unchanged. Long-premium structures like a long put on IMSR 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 IMSR chain quotes before placing a trade.
