PLX (Protalix BioTherapeutics, Inc.) trades in the Healthcare sector, specifically Biotechnology, with a market capitalization of approximately $211.1M, a trailing P/E of 11.06, a beta of 0.01 versus the broader market, a 52-week range of 1.46-3.19, average daily share volume of 697K, a public-listing history dating back to 1998, approximately 226 full-time employees. These structural characteristics shape how PLX stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 0.01 indicates PLX has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. The trailing P/E of 11.06 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price.

What is a cash-secured put on PLX?

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.

PLX snapshot

As of August 14, 2026, spot at $2.24, ATM IV 34.80%, IV rank 6.28%, expected move 9.98%. The cash-secured put on PLX below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.

Why this cash-secured put structure on PLX specifically: PLX IV at 34.80% is on the cheap side of its 1-year range, which means a premium-selling PLX cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 9.98% (roughly $0.22 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated PLX expiries trade a higher absolute premium for lower per-day decay. Position sizing on PLX should anchor to the underlying notional of $2.24 per share and to the trader's directional view on PLX stock.

PLX cash-secured put setup

The PLX 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 PLX at $2.24 on that close, the first option leg uses a $2.13 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PLX chain at a 35-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 PLX shares for the stock leg in covered calls and collars).

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

PLX thesis for this cash-secured put

The market-implied 1-standard-deviation range for PLX extends from approximately $2.02 on the downside to $2.46 on the upside. A PLX cash-secured put lets a trader earn premium while waiting to acquire PLX 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 PLX IV rank near 6.28% 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 PLX at 34.80%. As a Healthcare name, PLX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PLX-specific events.

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