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 FULC snapshot

As of June 30, 2026, spot at $3.80, ATM IV 206.20%, IV rank 40.03%, expected move 59.12%. The cash-secured put on FULC 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 17-day expiry.

Why this cash-secured put structure on FULC specifically: FULC IV at 206.20% is mid-range versus its 1-year history, so the credit collected on a FULC cash-secured put sits in line with its long-run distribution, with a market-implied 1-standard-deviation move of approximately 59.12% (roughly $2.25 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated FULC expiries trade a higher absolute premium for lower per-day decay. Position sizing on FULC should anchor to the underlying notional of $3.80 per share and to the trader's directional view on FULC stock.

FULC cash-secured put setup

The FULC 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 FULC near $3.80, the first option leg uses a $3.61 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FULC chain at a 17-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 FULC shares for the stock leg in covered calls and collars).

FULC thesis for this cash-secured put

The market-implied 1-standard-deviation range for FULC extends from approximately $1.55 on the downside to $6.05 on the upside. A FULC cash-secured put lets a trader earn premium while waiting to acquire FULC 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 FULC IV rank near 40.03% is mid-range against its 1-year distribution, so the IV signal is neutral; the cash-secured put thesis on FULC should anchor more to the directional view and the expected-move geometry. As a Healthcare name, FULC options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FULC-specific events.

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