Current REM snapshot
As of May 15, 2026, spot at $21.77, ATM IV 25.00%, IV rank 3.87%, expected move 7.17%. The collar on REM 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 REM specifically: IV regime affects collar pricing on both sides; compressed REM IV at 25.00% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 7.17% (roughly $1.56 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 REM expiries trade a higher absolute premium for lower per-day decay. Position sizing on REM should anchor to the underlying notional of $21.77 per share and to the trader's directional view on REM etf.
REM collar setup
The REM 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 REM near $21.77, the first option leg uses a $23.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed REM 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 REM shares for the stock leg in covered calls and collars).

| Buy 100 shares | Stock | $21.77 | long |
| Sell 1 | Call | $23.00 | $0.21 |
| Buy 1 | Put | $21.00 | $0.48 |

When traders use collar on REM
Collars on REM hedge an existing long REM etf position; the long put sets a floor while the short call finances it, often run as a near-zero-cost hedge during expected volatility windows.
REM thesis for this collar
The market-implied 1-standard-deviation range for REM extends from approximately $20.21 on the downside to $23.33 on the upside. A REM collar hedges an existing long REM 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 REM IV rank near 3.87% 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 REM at 25.00%. As a Financial Services name, REM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to REM-specific events.
REM 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. REM positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move REM alongside the broader basket even when REM-specific fundamentals are unchanged. Always rebuild the position from current REM chain quotes before placing a trade.
