Current EQ snapshot
As of May 15, 2026, spot at $2.21, ATM IV 116.70%, IV rank 20.28%, expected move 33.46%. The cash-secured put on EQ 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 EQ specifically: EQ IV at 116.70% is on the cheap side of its 1-year range, which means a premium-selling EQ cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 33.46% (roughly $0.74 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 EQ expiries trade a higher absolute premium for lower per-day decay. Position sizing on EQ should anchor to the underlying notional of $2.21 per share and to the trader's directional view on EQ stock.
EQ cash-secured put setup
The EQ 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 EQ near $2.21, the first option leg uses a $2.10 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed EQ 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 EQ shares for the stock leg in covered calls and collars).

EQ thesis for this cash-secured put
The market-implied 1-standard-deviation range for EQ extends from approximately $1.47 on the downside to $2.95 on the upside. A EQ cash-secured put lets a trader earn premium while waiting to acquire EQ 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 EQ IV rank near 20.28% 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 EQ at 116.70%. As a Healthcare name, EQ options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to EQ-specific events.
EQ 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. EQ positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move EQ alongside the broader basket even when EQ-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on EQ carry tail risk when realized volatility exceeds the implied move; review historical EQ earnings reactions and macro stress periods before sizing. Always rebuild the position from current EQ chain quotes before placing a trade.
