Current RMBS snapshot

As of May 15, 2026, spot at $127.14, ATM IV 75.90%, IV rank 49.93%, expected move 21.76%. The cash-secured put on RMBS 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 cash-secured put structure on RMBS specifically: RMBS IV at 75.90% is mid-range versus its 1-year history, so the credit collected on a RMBS cash-secured put sits in line with its long-run distribution, with a market-implied 1-standard-deviation move of approximately 21.76% (roughly $27.67 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 RMBS expiries trade a higher absolute premium for lower per-day decay. Position sizing on RMBS should anchor to the underlying notional of $127.14 per share and to the trader's directional view on RMBS stock.

RMBS cash-secured put setup

The RMBS cash-secured 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 RMBS near $127.14, the first option leg uses a $120.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed RMBS 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 RMBS shares for the stock leg in covered calls and collars).

RMBS thesis for this cash-secured put

The market-implied 1-standard-deviation range for RMBS extends from approximately $99.47 on the downside to $154.81 on the upside. A RMBS cash-secured put lets a trader earn premium while waiting to acquire RMBS at the strike price; the strategy is most attractive when the trader is comfortable holding the underlying at that level and IV is rich enough to compensate for the assignment risk. Current RMBS IV rank near 49.93% is mid-range against its 1-year distribution, so the IV signal is neutral; the cash-secured put thesis on RMBS should anchor more to the directional view and the expected-move geometry. As a Technology name, RMBS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to RMBS-specific events.

RMBS cash-secured put positions are structurally neutral to slightly bullish; 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. RMBS positions also carry Technology sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move RMBS alongside the broader basket even when RMBS-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on RMBS carry tail risk when realized volatility exceeds the implied move; review historical RMBS earnings reactions and macro stress periods before sizing. Always rebuild the position from current RMBS chain quotes before placing a trade.
