Current RDNT snapshot
As of May 15, 2026, spot at $52.11, ATM IV 53.90%, IV rank 34.54%, expected move 15.45%. The collar on RDNT 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 collar structure on RDNT specifically: IV regime affects collar pricing on both sides; mid-range RDNT IV at 53.90% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 15.45% (roughly $8.05 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 RDNT expiries trade a higher absolute premium for lower per-day decay. Position sizing on RDNT should anchor to the underlying notional of $52.11 per share and to the trader's directional view on RDNT stock.
RDNT collar setup
The RDNT collar below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With RDNT near $52.11, the first option leg uses a $55.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed RDNT 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 RDNT shares for the stock leg in covered calls and collars).

| Buy 100 shares | Stock | $52.11 | long |

RDNT thesis for this collar
The market-implied 1-standard-deviation range for RDNT extends from approximately $44.06 on the downside to $60.16 on the upside. A RDNT collar hedges an existing long RDNT position with a protective put while financing the put cost via a short call; when the premiums roughly offset, the collar acts as a near-zero-cost insurance band around the current spot. Current RDNT IV rank near 34.54% is mid-range against its 1-year distribution, so the IV signal is neutral; the collar thesis on RDNT should anchor more to the directional view and the expected-move geometry. As a Healthcare name, RDNT options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to RDNT-specific events.
RDNT collar positions are structurally neutral (protective); 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. RDNT positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move RDNT alongside the broader basket even when RDNT-specific fundamentals are unchanged. Always rebuild the position from current RDNT chain quotes before placing a trade.
