What is a cash-secured put on SWX?

A cash-secured put sells an out-of-the-money put while holding cash equal to the strike-times-100 obligation, keeping the premium when the underlying stays above the strike.

Current SWX snapshot

As of May 15, 2026, spot at $87.44, ATM IV 25.50%, IV rank 3.25%, expected move 7.31%. The cash-secured put on SWX 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 SWX specifically: SWX IV at 25.50% is on the cheap side of its 1-year range, which means a premium-selling SWX cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 7.31% (roughly $6.39 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 SWX expiries trade a higher absolute premium for lower per-day decay. Position sizing on SWX should anchor to the underlying notional of $87.44 per share and to the trader's directional view on SWX stock.

SWX cash-secured put setup

The SWX 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 SWX near $87.44, the first option leg uses a $83.07 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SWX 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 SWX shares for the stock leg in covered calls and collars).

Cash-secured puts on SWX earn premium while a trader waits to acquire SWX stock at a target strike below the current quote; most attractive when IV is rich and the trader is comfortable owning SWX.

SWX thesis for this cash-secured put

The market-implied 1-standard-deviation range for SWX extends from approximately $81.05 on the downside to $93.83 on the upside. A SWX cash-secured put lets a trader earn premium while waiting to acquire SWX 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 SWX IV rank near 3.25% 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 SWX at 25.50%. As a Utilities name, SWX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SWX-specific events.

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