Current REPL snapshot

As of June 30, 2026, spot at $11.12, ATM IV 193.06%, IV rank 42.18%, expected move 55.35%. The collar on REPL 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 31-day expiry.

Why this collar structure on REPL specifically: IV regime affects collar pricing on both sides; mid-range REPL IV at 193.06% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 55.35% (roughly $6.15 on the underlying). The 31-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated REPL expiries trade a higher absolute premium for lower per-day decay. Position sizing on REPL should anchor to the underlying notional of $11.12 per share and to the trader's directional view on REPL stock.

REPL collar setup

The REPL 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 REPL near $11.12, the first option leg uses a $12.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed REPL chain at a 31-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 REPL shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 100 shares	Stock	$11.12	long
Sell 1	Call	$12.00	$2.03
Buy 1	Put	$11.00	$2.33

REPL thesis for this collar

The market-implied 1-standard-deviation range for REPL extends from approximately $4.97 on the downside to $17.27 on the upside. A REPL collar hedges an existing long REPL 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 REPL IV rank near 42.18% is mid-range against its 1-year distribution, so the IV signal is neutral; the collar thesis on REPL should anchor more to the directional view and the expected-move geometry. As a Healthcare name, REPL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to REPL-specific events.

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